Primordial Gods

Way of the Necessary Evil

Student of the Deadly Arts is good in principle, giving you an advancing series of choices to help you. However, this is all you get, and you'll get one of three Disciple techniques and up to four Asssassin techniques (one per Tier), so they'd better be really good.

The Disciple techniques are frankly dissapointing. Deception gives you Advantage on two skills you aren't going to be very good at if you're even proficient and a tool proficiency that's not as good as a 1st level spell much of the time, Distraction gives you a skill you're good at an a spell that's kind of meh, and Destruction gives you a really weak spell and encourages you to use Poison damage which we all know kind of sucks at later levels. Seriously, why would you turn Melf's Acid Arrow into Poison damage? What can poison hurt that acid can't?

So how are the techniques? Meh. Some are distractions that aren't likely to be worth the trouble, some give you tricks with poison,...See more and 11th level Venom from the Void should just be a class feature because you're going to have to waste a pick on it if you use poison at all, and if you aren't using poison, what the heck are you? A Monk without a subclass? Sure, you can instead pick up the ability to cast Hypnotic Pattern with Ki, and that's a good spell, but you get that at Lv 11 and the Warlock picked it up at Lv 5.

Monks are famously weak; this needed to be a lot better to counteract that.

Time Domain

Your Domain Spells are great ones to get for free. Especially Counterspell. Honestly, some of the ones on this list aren't a big deal, but-- COUNTERSPELL!

Disciple of Time is a language proficiency, in a language that, explicity, isn't commonly used. Not great. Glimpse of the future is a little bit better, but an AC boost when surprised is circumstantial, and moving your position on the Initiative chart is only useful now and then. Besides, that uses your Reaction, and you want that for COUNTERSPELL!

Channel Divinity: Chronostasis is pretty cool, even if it only protects you from Ranged Spell or Weapon Attacks. It's just really fun, so I can't complain about it. A shame that you have to use it before you know if it was a hit, though.

Alternative Timeline is okay, letting you, in effect, give a creature Disadvantage on a roll of any kind, which is good, especially for, say, going "Save against my Banishment/Plane Shift/Geast oh wait ROLL...See more AGAIN," but it's once per Long Rest, which is much more limited than other features.

Great Flow of Time is constructed incorrectly, in that all Cleric Lv 8 Features are one of two damage boosts, three options if you have Tasha's. The actual feature isn't that great, but to be fair, neither are the Cleric damage boosts.

Master of Time, though, is three Features in one that aren't really connected to each other. Time Stop is pretty good, certainly. Healing other people with your hit dice isn't that good. I mean, you're a Cleric. How many spell slots do you have to cast Healing Word or Cure Wounds? The spell storing one seems to have a grammar issue in that it says spells with a 'Duration' of one action. Was that intended to be casting time? Nothing has a duration of one action. Either way, the combo makes this a pretty good feature.

Overall, this is okay but not great. Most of the features are kind nice but not really any big deal, until you get to Master of Time, and that's 17th level and a long wait.

Temporal Conclave

Time Blip is pretty great-- it's a bit like Shield-- but the limited uses are just that, pretty limited. It also has an awkward clause in that you aren't aware of events around you and can't interact with anything until your next turn, but this was your Reaction, so what does that mean? Does the player have to leave the room until their next turn? Aberration Hunter is pretty minor, because Favored Enemy is a ribbon. And good Ranger subclasses have a damage boost here; not having one limits this subclass already.

In the Present Moment is a list of ribbons until you get a feature that lets you use your React to add your Wisdom mod to your AC, and I guess that fills in for Time Blip, unless you boosted your Wisdom, in which case it makes Time Blip completely irrelevant. That's not good design. Rangers need offense!

Grounded in the Present is odd. Most Rangers take Hunter's Mark anyway, although it's not that good a spell. (Conjure Animals or Spike Growth...See more or even Summon Beast are better!) The boosts to Hunter's Mark help only slightly; stopping teleportation is only good against certain enemies, and stopping movement in your Favored Terrain is very circumstantial, but I guess that combines to make this kind of OK?

Timed Recall is tricky. Fundamentally, what it does is remove all damage you've taken in the current round and remove all Conditions you suffered, as well as moving you back to where you started the round, and that's pretty good except that you want this most when you're unconscious, and you can only do that in your Favored Terrain. I think you'd do better doing something offensive and trusting your allies to heal you.

So this has some interesting features, but they're too defensive, and you need offense, period.

School of the Interdimensional Librarians

Interdimensional Library is an odd thing; some campaigns wouldn't care much about it at all. But in some games, it would be very valuable, so it's circumstantially good. Researcher Training gives you a spell DC boost, if limited, that's certainly good (if flavorless), plus a Proficiency that's usually welcome.

Expanded Library is much more specialized. And limited. And it's a ribbon, being entirely fluff rather than anything useful.

Master Librarian has a couple of useful tricks, notably a better boost to Spell DCs (which is very good indeed here), plus the ability to cast a spell that isn't prepared. That's enough to make this a solid feature.

Theory into Praxis is very good, for while Wizards have the best spell list, hands down, there's still a number of tricks that other casters have that they can't touch. So, you now have an answer to "Who casts Raise Dead on the Cleric?" which is nice... but this...See more also means that the caster will have a Greater Steed immediately. (It's a permanent spell with no real cost. Why not keep trying it on your rest days?)

So overall this is good and interesting, but the parts that are good are flavorless, and the parts that are interesting don't do much. But enjoy riding your griffon or pegasus.

Soulful

Empathetic Soul is okay; Calm Emotions is a versatile spell, if specialized, and a free Proficiency is always appreciated.

Emotion Projection, however, is amazing. Sure, you can use it like a Shield spell to reduce an attack roll against you, but why would you bother, when you can give them a Saving Throw penalty against your Web or Hold or Banishment spell and just stop them from attacking you at all? Anything that does this is going to be very, very valuable to a spellcaster.

Emotional Intelligence is interseting. The combination of Fear resistance and Surprise immunity is already good, and giving out an Initiative bonus is certainly nice... but if your GM lets a Sorcerer pick up Gift of Alacrity, that part seems much less important. But the combo is very good, because it's a combo.

Manifest Emotions is silly to roll for, but if you're not rolling and just pick an option, the sheer versatilty is quite good, and some of these are great, but watch...See more out for the ally-unfriendly debuffs... and the enemy-unfriendly buffs. Was it worth setting enemies on fire to give all of your allies Disadvantage on their Weapon Attacks for the rest of the fight? Your allies might have an issue with that.

Complex Emotions drains a lot of Sorcery Points to combine the above. That's okay but not great, considering the big non-selective auras.

Overall, this is good. But watch those 30' radius "all creatures" effects. Those are hard to use well.

Path of the Realist

Firmly Grounded is kinda okay, in that it deals with a circumstance that can knock a Barbarian out of Rage-- being unable to reach an opponent. That's still pretty minor as these things go, though, and I'd hope for better.

Mindfulness Personified is too specific to be useful. I've been in entire campaigns where illusions don't matter, and what are 'Basic Illusions,' anyway? Please be explicit.

Parting the Waves has one ribbon-- Water breathing is useless much of the time and the odds are good someone will just cast Water Breathing on the whole party. Besides, what if your Rage ends while you're underwater? The Primal Roar aspect REALLY needs an explanation fo what it means. "Create pathways" isn't a description. Do you dig tunnels?

Reality Bending is okay, but a lot of the benefits depend on the environment, and the rerolls are pretty limited. Advantage on Str and Con saves is good, though.

Barbarian Subclasses...See more really need to boost something Barbarians normally do-- adding damage, making them even tougher, or boosting their ability to tank for their allies. This one doesn't do any of that, so I think it needs work.

Pact of the Void

(Okay, this should be Void Patron. Pact of the Void makes it sound like it should be competition for Pact of the Tome or Pact of the Chain.)

The spell list has a mix of meh and good, like most Warlock expanded spell lists. Fear and Command stand out here.

Whispers of the Void, however, is trash. Expertise with Insight for a class that maybe has a Wisdom of 12? Even with the promise of the DM MAYBE giving you extra information, this is just not good, especially if you look at what the good Patrons get. (Seriously, compare this to not just Hexblade or Genie but even Fathom, Fiend or Celestial.)

Touch fo the Void is silly. Adding 1d6 Psychic damage with a Weapon attack on a spellcasting class? If you wanted to be good with weapons, you should play a Hexblade. You aren't one, so you are using Simple weapons and attacking with Str or Dex and even if you took the Blade Pact, this isn't worth it.

Tainted by the Void is a ribbon....See more How often in most games are divination spells targeting only you even going to matter?

Void Born suddenly is much better-- Resistance to the Weapon Damages is very good; lots and lots of monsters *don't* inflict magical weapon damage. Passing through solid objects can be handy, and while needing to make your Ghost act with your Action isn't good at all, their abilities are good enough that this might find some use, despite the normal problems with this kind of summon.

But it's far too late in the class to make up for the first three features being terrible. This is not a good subclass.

While I'm at it, my take on the Invocations:

* Eldritch Knowledge is terrible. A Feat can give you an Invocation, so maybe they should be comparable. A Feat can give you two Cantrips and a spell once per day. The only real use of this that I can see is if you want to play a Blade Pact warlock that isn't a Hexblade that does use their Spell Attack for attack and damage, and that's too much fuss to be something that a Hexblade can still outperform.

* Teachings of the Shade is fine. Two Proficiencies, and if they aren't for your best stat, at least Stealth is very useufl.

* Chaining Blast is pretty good! Immobilizing a target with a ranged attack as much as you like? Yep, I'm there for that. Combine with Repelling Blast for best effect.

* Costly Recall seems like a risky trade, but often worth it, especially at higher levels when 5d6 damage isn't that much of a price to pay.

* Whispers of the Mind is fine.

* Launch Through The Veil is silly, because Warlocks can already take Banishment and cast it with their regular Pact Magic slots.

* Grasp of Pestilence is potentially useful for the right character.

* Step Through The Void is amazing, especially for a Warlock who uses Cantrips a lot anyway.

I'm going to be short and sweet about Oath of the Time Defender: I would HATE to GM one of these. There's too many loose, wide-open, needing-GM-careful-thought powers in here. I'd vastly prefer something more solid.

Dream-Thief

Dreamsteal is interesting conceptually, but the effect is odd. A bunch of Temp HP is certainly very useful, but killing the enemy so that you don't take the damage is pretty much always going to be even more useful. This still can help you in an emergency, though, so it's hardly useless. Dreamshaper's sleep immunity won't come up that often, but still will have uses; the ability to see the shape of an unconscious target's dreams, however, is very campaign-specific. It might be vitally important or it might never matter in the least.

Improved Dreamshaper is, again, pretty specific. Too much so to be a great feature, to be honest.

Improved Dreamsteal, however, has some nice advantages-- copying an ability from a target could be very powerful, and at this level, I'd actually expect it to give you more options. But the potential utility of stealing a Resistance or Blindsight or a mysterious language is very real. Still, why not open it up to Immunity or other...See more tricks? Rogues don't get a lot anyway; the more the merrier!

Dream Traveler is just not going to be that great. Sending only yourself into astral space is either going to risk getting you killed or, at best, leave the party waiting for your solo adventure to end. Much less useful than Etherealness would be.

Overall, this is a little bit meh. Rogues need good stuff from their subclass, and this doesn't really provide enough of it, but it's still got a few good tricks in there.

College of the Stars

Cosmic Radiance is certainly creative, and inflicing Radiant damage as a Reaction is good, but the amount is small. The real boost is the blinding effect, and that's definitely good, since the duration will extend into the next round. (The fact that it's a Con save limits it, however.) Ballet Training is minor, though. Performance skill is something most Bards have, and not that useful; the Light cantrip isn't terribly important, either, and Radiant damage isn't common.

Localized Gravity is particularly useful as it's not limited in the number of uses, as well as being a Reaction. That's very versatile-- it's great for Walls of Fire and Spike Growth, but would also be useful to, for example, pull an ally clear of the followup attacks of a Hydra after it hits them once. This is good, and should be great fun.

Ballet of the Stars is good, but with a noteworthy limitation-- it takes an Action to activate but only lasts 1 minute, so you're probably going...See more to be using this during a fight and thus scacrificing your chance to, say, cast Hypnotic Pattern on a cluster of enemies. It's really worth it, though, to be able to fly and drag enemies around... and the possibility of using both in concert to drop them from a great height or into obstacles is obvious. The Cosmic Pulse aspect isn't that great; the damage is too small to mean much at this level, but the mobility and control (no-Concentration Flight is always nice) will be useful.

Overall, this is interesting and different. Not the strongest Bard, but still decent, at least.

Circle of Corruption

The Circle Spells are a mix, but there's several good ones in here, and I wouldn't ask for more than that. As an extra bonus, several aren't Concentration spells, which is good, since the best spells of Druids are all Concentration.

Corrupt Beast is very powerful, but with a limit, since it depends on what Beasts you encounter. In some games, this could be useless, but I imagine that Beasts will turn up eventually, and in some games, this is going to be extremely powerful, the more so since there's no Save against the effect. The duration is almost meaningless-- yes, it's as long as Wild Shape, but by 4th level, two hours means that you can take a Short Rest before the duration is expired to extend the time, and at higher levels, it's going to be trivial to keep your corrupted Brown Bear as long as it survives. At low levels, this is going to be very good-- adding 1d8 damage to each attack of an ordinary bear or wolf is very strong, and this doesn't use Concentration...See more and can't be resisted. On top of all of this, the ability to remove an enemy from the fight permanently with no Save and turn them into a more-powerful ally is a Bonus Action! But at higher levels, this is going to be less useful, as you're limited to CR 1 Beasts, and nothing that this class provides increases either their Attack bonus, and the AC and HP boosts that come along later won't boost their survival enough. Likewise, the ability to remove a Beast from the fight won't matter once you stop encountering CR 1 enemies.

6th level improving your Beast is making an already strong feature better; notably, Primal Frenzy combined with the boost to damage inflicted is increasing the power of this abilty dramatically. But this is best at the level you get it at; CR 1 Beasts

Void Shaping is very powerful, but the wording keeps it from getting entirely out of hand, IF I'm reading this correctl. It looks like you can only summon a CR 1 creature, but this is still very good-- it's a no-Concentration flying mount, for example, and the burst of damage that Primal Frenzy can give you is strong, but again, CR 1 Beasts are limited.

Greater Tangibility almost feels like a waste for the ability to transform the kind of Beast you get; you just aren't going to encounter a lot of CR 1 Beasts at 14th level anyway; you might need to rely entirely on Void Shaping to provide Beasts. The ability to turn a Beast into a Humanoid isn't clearly defined. Can it be ANY Humanoid in the book? Is it subject to the CR limit? The extra damage here is fine, but wasted on a CR 1 Beast that will die quickly and will miss a lot. The HP aren't enough to let the Beast survive, as noted elsewhere.

Overall, this one is very strong at low levels, but quickly becomes irrelevant as the Corrupted Beasts become much less powerful relative to the opposition. Better to look at the Tasha's summoning spells for guidance, in my opinion.

You asked for feedback; I'll give you some on the subclasses. This is going to be a multi-post because I want to be specific.

Armourer of the Ages:

Armoury of the Ages is largely a ribbon; being able to swap weapons in and out isn't very useful most of the time, and how often will you need to change weapons mid-attack? The only benefit is being able to have a weapon count as magical on the first attack of a turn when it isn't magical, and that will stop mattering when you acquire your first magical weapon. While there are circumstances where this could be useful, they are just that-- circumstantial-- and this can't possibly compare with the likes of spellcasting, Expertise Dice, Runes, or even Fighting Spirit. Cosmic Knowledge is fine as a minor add-on, but that's all that it is-- an Eldritch Knight gets Arcana plus spells which will be useful all the time!

Arsenal of the Ages is similarly limited; handy if you're attacked while sleeping, but otherwise, how often will...See more you need it? The +1 to AC isn't bad, but since it goes away once you get hit, it's not really that useful.

Master of the Armoury is much better. Ignoring cover with ranged weapons isn't tremendously significant-- a specialist in this kind of thing will have Sharpshooter by now, surely! But, as a bonus action, you can teleport 30', and that's *amazingly* good. The fact that you can ALSO knock enemies Prone when you do so (and inflict a trivial amount of damage) is even better, the more so since you can then attack your fallen enemies with Advantage. I'm not going to object in the least to how powerful this is; Fighters at this level start falling behind spellcasters rapidly, and this helps keep them even.

Cosmic Ward has complicated wording, but it's basically the ability to take your action to make a single melee attack against a number of enemies who are within 10' of you or who enter that space. It's potentially a large number of attacks, but a single blow against each one isn't all that impressive. For 15th level, I'd expect it to be better.

Living Armour is a great idea, but why is it so limited? At 18th level, it shouldn't be a matter of using your Attacks to let the mannequin attack-- this is less good than what an Echo Knight gets at 3rd level. Granted, Echo Knights are incredibly good, but this just isn't a good feature for 18th level.

So overall, the 10th level feature is amazing, but almost everything else is pretty marginal for the level. I'd especially improve Armoury of the Ages-- a Fighter's 3rd level Feature needs to really define how they fight, and this just doesn't. (It doesn't help that while in 3e, Fighters needed a vast array of weapons to adapt to different foes, in 5e, there just aren't enough Resistances and Immunities that you can get around that way.)
