Gemesaur King
The Gemesaur King is a boss in A Link Between Worlds, whose lair lies hidden at the bottom of the Dark Palace. He guards the portrait of the sage Gulley.
Strategy
Unlike the Helmasaur King from A Link to the Past, who is a bulky ranged attacker, the Gemesaur King is an agile physical attacker. This can be noted due to the fact that he does not breath fire like his Hyrulean counterpart, but rather charges at Link. The strategy to defeat Gemesaur King is to throw Bombs at his mask to damage it. If a Bomb explosion hits any of the crystals on its back, Rupees will be dropped.
Once the mask is broken, the Gemesaur King will attempt to confuse Link by turning the room pitch black. He will dash around the perimeter of the room and try to trample Link, who must use the Lantern or the Fire Rod to light the two torches in the bottom right and the top left corners. This will reveal the Gemesaur King, stopping his mad dashing and allowing Link to attack the jewel on his head with his Sword.
Trivia
- Its name is a portmanteau of gem and Helmasaur King.
