Nether Gammara

Hell Gammara (also known as Nether Gammara) is the Nether equivalent to a Gammara. They are twice stronger than a normal Gammara.

Tactics
Nether Gammaras comes out of Lava and becomes a boss once you throw any potion and Iron in the Lava. They can kill a Diamond Golem with two hits and a Wither with the same hits as a Diamond Golem. If you use Emerald Pickaxe or 13 Splash Potions of Regeneration, you can be lucky to kill it faster. They die and do the same as regular Gammaras but spawns 2 Fire Golems instead.
