Core Rules › 429 › 429.5Rule 429.5.bA spell or ability that contains a Kill instruction is responsible for Killing the Unit or Gear.Rulings that cite this ruleWhat does it mean to “kill a unit with a spell?” It seems like Hidden Blade counts, but what about a spell that deals damage? A spell that causes a unit to deal damage? A spell that causes a unit to die in some other way, like Stupefy on a unit that has 1 more Might than it has damage currently marked on it?Official Core Rules
