I wish the dev would allow this to be treated like the Cleric burst effect for undead.
yes I know it would be weak maybe 40 to 50 damage but at least it would do some.
Look at it this way positive when hitting undead does damage and allows you to gain 1-3 hp back per hit. So why doesnt the finishing move do positive burst and damage undead like the clerics burst? It already does the burst for healing all in your party in an area effect just add the effect to undead.
