Gain the Void Spell School. Shadow Blast and Shadow Minions may deal Void damage.

When summoning Shadow Minions, you may have them instead become Void Souls. Instead of being able to attack directly, they can move into the space of an ally and empower them. adding their damage to each of the ally’s attacks. If that ally takes damage, the attacker becomes Weakened if adjacent and all void souls empowering them die.

You may target allies with Shadow Blast and give them Temp HP instead of damaging them.

When a blessed ally is would be damaged, 1 minion blessing sacrifices itself to negate that damage and make the attacker Weaken (at any range).

(1/Safe Rest) For 1 round you are immune to all damage and negative effects. Anytime you would roll a d20, roll a d100 instead, and anytime you would roll less than a d20, roll a d20. All damage you deal is Void and makes targets Weak.
