Upon being killed for the first time during a single Campaign at level 5 or higher, he drops Leoric's Crown. On Torment difficulty, he has no enrage timer. The King has a large amount of Life, but moves slowly.
As long as the King is active, more groups of monsters will appear, but they disappear after he is defeated. Once the king is activated, numerous undead minions appear. His remains rest in the Royal Crypts deep within the Tristram Cathedral, and he can only be bound into a physical form by means of his old crown, which must be placed atop his head. The Skeleton King appears as the first major boss of Act I, standing between you and the Fallen Star.
