Gomess

Gomess is one of the many evils of the Stone Tower Temple in. It guards the Boss Key that Link needs to gain access to Twinmold's lair, and does not surrender it easily. It is a master with the scythe that it wields.

Strategy
Gomess is almost completely immune to harm with the sword while the Bad Bats 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 Bad Bats are scattered, Link can attack Gomess with any weapon of choice. The young hero must repeat this pattern until Gomess is defeated.

Trivia

 * Since every undead creature in Ikana was once alive before the doors of Stone Tower Temple were opened, and Gomess appears to be a ghost of some sort, it is possible that Gomess was once a normal living being. If anything, Gomess, just like the Garo, was an enemy of the Ikana royal family, because its scythe has a decapitated skull of an Ikana Soldier on top of it.
 * The only other entity made up of bat-like creatures in the Zelda series except Gomess is the Vire, that appears in, and the Oracle series. Otherwise in spin-off games, the Darknut boss of  also used bat-like creatures.
 * Gomess shares its French name with Death Sword, Faucheur, which means "harvester", alluding to the Grim Reaper.
