Xolotl

Xolotl the lightning spirit is a boss mob added by Legendary Beast mod.

Location
Xolotl can be found in a blue cloud layer found most easily in the minimap. He is accompanied by many charged creepers.

In Combat
Xolotl can use melee, but mostly uses his electric staff in combat. He summons charged creepers constantly to explode targets. He also strikes lightning randomly a lot. Lastly, he can only take damage from explosions and punches.

Strategy
it is recommended you are at least in between the iron and diamond phase as far as armor goes, and should have a knockback sword or explosion bow. If you use the former, creepers should be knocked towards Xolotl, as he only takes barefist/explosion damage. Golden apples must be used, but sparingly. If the latter is taken, avoid the creepers and shoot him into submission. The thick skin ability is advised regardless.

Drops
Xolotl drops a good amount of xp and a lightning staff to strike down lightning.
