I was excited to play the Pixie after reading about them, the ability of flight, being the smallest race, and the mischief all sounds fun...until I played them and they feel so...weak.

Pixies are unable to wear chestplates and have 5 hit points. Sure they can move at super speed and can fly, but they get one shotted in almost every situation because chestplates add THAT much to them, at most I would give them the Elvish chainmail ability or the Fae's inability to wear armor, because they have no defensive abilities whatsoever.

Their mischief ability is cool...except that it counts as a potion of harming, so it heals undead. I personally think it'd be more interesting if they could somehow choose the ability based on how you pressed it. maybe holding the button launches you, crouching and using it gives you regeneration, and using it by default creates the explosion. But if that was done, it NEEDS a cooldown. Hell it needs a cooldown regardless. the randomness of it is pointless without the cooldown.

If you still want to keep the randomness factor is how I would do it. Crouching has a chance to give you a random status effect with a small chance of either a debuff or Parrot noise rather than a buff.

Using the explosion by default inflicts a random debuff whether that be fire, poison, slowed, etc;. and of course a small chance to inflict a buff or Parrot noise.

Other than that a chaos focused race is cool...it's just so hampered by literally every other ability with its saving grace being the loot tables and fall damage immunity. The Fae is almost strictly better than it.
