Rule 143.2.b

If a Unit ever has nonzero damage marked on it equalling or exceeding its Might, it is Killed.

Rulings that cite this rule

• I heard that cards that reduce Might will no longer say “to a minimum of 1” on them. Does that mean Origins cards like Stupefy will receive errata?
• Does this mean that units’ Might can go to 0 or below now?
• Does a unit with negative Might contribute negative damage to my Might total in combat?
