Rule 429.5.b

A spell or ability that contains a Kill instruction is responsible for Killing the Unit or Gear.

Rulings that cite this rule

• What 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?
