Cadaver of Schalous

Midpoint. Rather than being at disadvantage, attacks made with double disadvantage(2DA) or higher are replaced with the median of that number of dice (#M). 

Mana Void. So long as the anti-mana crystal sits in the Mourner's Halberd, all magic within a 550ft radius of Schalous is rendered useless.
Sneak Attack. Once per turn, you can deal an extra 1d6 damage to one creature you hit with an attack if you have advantage on the attack roll. The attack must use a finesse or a ranged weapon. You don't need advantage on the attack roll if another enemy of the target is within 5 feet of it, that enemy isn't incapacitated, and you don't have disadvantage on the attack roll.
Polearm Manipulation. Treat all polearms as finesse weapons.
Cunning Action. Starting at 2nd level, your quick thinking and agility allow you to move and act quickly. You can take a bonus action on each of your turns in combat. This action can be used only to take the Dash, Disengage, or Hide action.
Uncanny Dodge. Starting at 5th level, when an attacker that you can see hits you with an attack, you can use your reaction to halve the attack's damage against you.
Evasion. When you are subjected to an effect that allows you to make a Dexterity saving throw to take only half damage, you instead take no damage if you succeed on the saving throw, and only half damage if you fail.
Slippery Mind. By 15th level, you have acquired greater mental strength. You gain proficiency in Wisdom saving throws.
Elusive. Beginning at 18th level, you are so evasive that attackers rarely gain the upper hand against you. No attack roll has advantage against you while you aren't incapacitated.

Hard Counter. While holding a mele weapon, as a reaction to being attacked with a mele weapon, make a Dex save to lock your attacker in a bind, if they break said bind without disengaging, you get two hits off them. When you bind, you do not take damage, but failing doubles damage taken.
Soft Counter. While holding a polearm, as a reaction to ranged attacks, you can make a Dex check (DC: 21) to deflect the projectile. You can deflect projectiles up to your proficiency bonus per reaction, however, after the first, each check has disadvantage. The projectiles you can deflect must be aimed within or passing through 25 feet around you.
Lever Hurl. As a result of an attempted grapple or grabbed weapon, you can use your polearm to make a strength save and throw your attacker up to 60 ft away. the thrown attacker must make a Dex Save(DC: 30) upon hitting the ground or take half their weight in damage. 
Fast Twitch. As a reaction to ranged attacks, you can make a Dex save (DC:30) and lunge out of the way, returning with any attack that also has the Fast Twitch property.

Schalous can only use bonus actions on his turn, however, he can move and attack up to 3 times with his normal actions between turns.
