New Class(es) for D&D

[Therin]

I'm working on a new class for D&D based on one of the characters I played in a roleplay that never finished. That seems to be something that usually happens to my RPs, doesn't it...

Anyways, here's what I have so far. Anyone with DMing or other D&D experience is welcome to help, since the last time I played was about 6 years ago.

Mutant – Sonic Adept
HD – d8
Alignment – Any
Starting Skill Points – 2, 1 per level
Weapon Proficiency – None
Armor Proficiency – Cloth or Leather armor.
Attack – Sonic Burst: The Sonic Adept begins a fight with a certain amount of AP(five times his or her level) and regains 2 AP per level per round. To attack, the adept spends any amount of AP to deal that much damage multiplied by his or her level.

Feats:
Deflection – The adept attempts to use his sonic burst to deflect weapons. The larger and heavier the weapon, the harder it is to deflect. To do this, the adept spends any amount of AP and calculates his or her level plus the amount of AP spent. Then, he or she rolls a 20-sided die. If the die roll is less than or equal to the number previously calculated, then the deflection succeeds.

Class: Masochist
HD: d12
Alignment: Any Chaotic
Starting Skill Points: 4, 1 per 2 levels
Weapon Proficiency: Fists
Armor Proficiency: Leather, Cloth, Unarmored

The Masochist has a high threshhold for pain. He gains +1 to damage for every 10 HP he lacks from his total HP score, and always gets Max HP(No rolling-- 12 HP per level until level 9, and then +5 for every level after that.).

For instance, Bob is a level 12 Masochist. He has [12(9)+5(3)] HP. I don't feel like doing the math. With 20 HP taken away, he does +2 damage with each attack.
