50% recoil damage is a bit much, bit too damn much. Thats kill myself in one turn in pve too damn much

Void isn't portrayed as an explosive force that deals INSTANT damage and sickness to its users. It instead slowly poisons them and eats away at their health slowly.

Perhaps everytime you use a void skill you get a stack of a void poisoning status, that deals rank based void damage per turn.

Using any void assassin skill other than Fray, cutthroat and veiloff should increase the void poisonings strength, Veiloff which puts your void essence collecting off would also now serve as a way to shrug off the void poisoning in return for off-lining most of the classes skills.

Also I don't think nullstone is the right material to counteract the void anyway.
