Not really worth it in my opinion.

4 pages???

Try under a 1/2 page of content ... for the same recommended $$$ as an adventure that would give you 30+ pages!!!

Not good at all!

Pretty much copy-pasted from SCAG.

It's a weaker version of bladesinger. The proficiencies are the same, just trading a skill proficiency for simple weapon proficiency (which you are unlikely to use anyway since you are proficient with a martial weapon).

expending a spell slot for an average of 3 damage is pitifully weak. At that point, even with a melee-based wizard, you'd be better off blasting them with a Magic Missile at point blank than using the level 2 feature.

Extra attack comes at the same time as bladesinger

Arcane ward is literally song of defense, but 4x the spell's level instead of 5x (what bladesinger offers)

And easy coating amounts to an average of +3.5 damage per strike, while Song of Victory (+int to damage on melee weapon) should be giving you at least +4 at this level, if not +5.

The layout is okay.

Really unprofessional. Waste of $. It is poorly put together.

I'd recommend giving the Warmage the ability to add their Intelligence bonus to their AC when unarmored if they're ever going to be entering melee with their meager hit points.

For arcane coating - it's spelled exp-e-nd, not "expand".
