The Giant King is a dungeon exclusive boss monster found in Giant's Keep and entered using the Giant's Keep Key. A stronger version is found in the RISE OF INFO dungeon.
Although giants are weak against crush type weapons, the Giant King does not seem to specifically have any strengths or weaknesses.
The Giant King will become the Enraged Giant King once defeated.
The Giant King has many attack types with a predetermined rotation.
Auto Attack -> Sweep -> Lash Out -> Auto Attack -> Savage Strike -> Lash Out -> Savage Strike -> Lightning Strikes Thrice -> (Repeat)
|Lightning Strikes Thrice
When fighting with less than 5 players, multi-target attacks can target the missing player slot thus hitting less players.[?]
E.g. Lightning Strikes Thrice can hit 2 or 3 players when fighting with 4 players.
