The Soulknife, 5e Class

A slight critique, for Balance purposes the Mind Blade should only deal 1 damage type, it also should not grant a free cantrip. Furthermore I would tone the damage down to match the Monk Martial Arts damage. Maybe allow the expenditure of Psi points to grant Weapon Traits like Versatile, Finesse, Light, ect. to allow for a more varied build type. For the Psicaster I feel having the abilities be closer to the Eldritch Knight pf the Fighter be a little more balanced for example the Armed Caster ability you gave it is relatively useless as the Mind Blade does not grant Two Weapon Fighting and Spellcasting only requires 1 free hand to for casting a spell, as noted in the PHB the same hand can do both the Somatic Component and the Material Component of spellcasting. However as the Mind Blade doesn't say you can't be disarmed the Eldritch Knight's Weapon Bond would grant you the bonus of not being disarmed, the summoning part is a bit of a mute point as the Mind Blade can already be summoned. Or you can instead move...See more the Energy Blade ability to the level 3 slot and drop the part about adding damage types to the blade as well as the Psy cost, instead just have it as a Bonus Action to change the damage type of the blade, though to be fair I would save that for a higher level level 10 maybe. Your Level 15 ability is already the Level 18 ability of the Eldritch Knight so I would just move that there and replace your Level 7 with the Eldritch Knight's level 7 so that it ramps up logically. I would then take the Level 10 ability you have and either move that to 15 or keep it there and move the Energy Blade to 15. Lastly I think developing some form of Archer Archetype would do this class a lot of good and round it out really well. I hope you take my critique kindly as I only meant it to help you flush this class out more.

Shouldn't the MINDBlade have Concentration to justify it's Short Rest Recovery? the PSI-Blade acts more like meta-magic of Empowerment of Blade/Spell. the Sorcerer Points takes a LONG rest to Recover; Balancing it's POWERed Attacks.

Can the MIND Blade have a (Finesse) Quality?

Really nice class but can you update this it could use some more specification on almost everything such as what skill do I use for my mind blade what sort of actions do you use for psi powers?

I think that more information needs to be given for using the mind blade as a ranged weapon. Things such as if it consumes ammunition, and if it does not, would it still have special rules like 'loading' for crossbows.
Is the weapon considered identical to what it is based off (except for the dmg) or does it just look like your chosen weapon.

This looks pretty interesting. For your saving throws I might suggest a change. The rest of the core classes follow a theory of one strong and one weak saving throw. The strong ones are typically considered Dex, Con, and Wis while Str, Cha, and Int are weaker. This is mostly just a frequency of saves of those types kind of thing. You picked Str and Int for your soulknife, might I suggest changing str to dex or con.

This is definitely interesting, though I feel there are a number of problems with the class still. For instance, you make reference to a few things that aren't involved in 5e, such as the hardness of your weapon (which isn't normally important, since there are no core sundering rules. The Warlock's weapon that it summons doesn't have hardness for example). You make a mention of "bonus to your blade" but I'm not even sure what that would be in reference to. Overall there feels like there are too many choices. The fighting style and augmentations have some overlaps, and some of the abilities you can use your psi points on are either too costly or too low, as well as have a lot of things that basically do the same thing.

I'm posting this rather late, so this isn't well formatted and I can't get too in-depth, but I definitely feel this needs more work. It might be that this doesn't really fit as its own class, as well, but rather a subclass to a psychic class for 5e, whenever that might come...See more out. They've been fiddling with the Awakened lately, and apparently are putting out the full class in Unearthed Arcana whenever they get that figured out. I know there were a number of gripes dealing with the exact way the abilities worked.
