Gomess

Gomess, the Lord of Keese, is one of the many evils of the Stone Tower Temple. He guarded the Boss Key that Link required to fight Twinmold, and did not surrender it easily. He is a master with the scythe he wields.

When Gomess appeared before Link, a swarm of Keese that filled the room previously flocked to his body, defending him from almost all of Link's attacks. As quickly as Link dealt with the Keese, there was always more, drawn by their master to do away with the intruder. It was almost impossible to penetrate the shroud of Keese with his sword alone, and the Gomess was proving more than adapt with the scythe it held, so Link was forced to turn to other means to assist him. Eventually, he found two ways of dispersing the Keese; bombs, and Light Arrows. When Link used either of these, the Keese would scatter, leaving the Gomess vunerable to attack. After a drawn-out battle, the Gomess was eventually struck down, leaving the Keese without a known master and the Boss Key without a guardian.

Strategy
The Gomess is almost completely immune to harm with the sword while the Keese cover its body; only a very lucky hit will penetrate. To disperse the cloud, bombs and Light Arrows are the way to go. When the Keese are scattered, attack the Gomess with a weapon of choice. Repeat this pattern until the Gomess is defeated.

Trivia
