Skeleton King (Diablo)

""The power of the fallen star awakened me, and soon, all will suffer as I have suffered!" -Leoric the Skeleton King, Diablo III" Leoric the Skeleton King is a mid-boss in Act I of Diablo III and Diablo III: Reaper of Souls, released in 2014 for Microsoft Windows, Mac OS X, PlayStation 3, Xbox 360, PlayStation 4 and Xbox One. He also appears in Diablo I as simply the Skeleton King, and Diablo II is only mentioned in the unique necromancer wand, the Arm of King Leoric. Leoric also appears as a playable character in Heroes of the Storm.

Gameplay (Diablo III)
The Skeleton King appears as the mid-boss of Act I, standing between you and Tyrael (the fallen star). 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 by the player(s).

Once this is done, numerous undead minions appear. As long as the King is alive, his minions will spawn continuously until he is defeated. Leoric has a lot of health, but at the same time is relatively sluggish and cannot move very quickly. On Torment difficulty, he has no enrage timer. When he is defeated the first time, he drops Leoric's Crown.

The Skeleton King appears as a quest in Adventure Mode and is one of the six bosses handpicked as an Uber Boss in the Infernal Machine event, under the title of the King of the Dead. His uber appearance boasts only significantly higher statistics, with no change in strategy, but he does fight alongside Uber Maghda. Like her, he can drop the Writhing Spine (Leoric's Regret) upon defeat. Crusader King is the Rift Guardian variant of the Skeleton King.

Gameplay (Diablo I)
The Skeleton King is a Unique Undead enemy whose form does not appear like any of the other undead types in the original Diablo. He is the reanimated corpse of the late King Leoric of Khanduras.

He is a Skeleton, but is much taller, wears a Crown and wields a huge Two-Handed Sword. In Single Player games with the Skeleton King Quest, he appears in a mini-level called King Leoric's Tombwhich is accessible from Dungeon level 3. After pulling the necessary Lever to open his chamber, he attacks the player with a small company of skeletons. The King can create more skeletons to replace the ones that fall in battle, so the player should make him their primary target.
