The ExtraBosses Mod is a mod that aims to make your Minecraft world a bit more challenging. The bosses in this mod are all naturally spawning, but very rarely. They are also balanced enough so you can defeat them with Vanilla tools. The mod currently only adds 3 bosses, and nothing else, but future updates will bring bosses and special drops for them, which may include weapons and other items that may be useful. Right now, they mainly just drop gems and golden apples. You deserve those if you find them and kill them!
There are currently 3 bosses in the mod:
Elder Ghast: only has 20 hp, but has a hard shell of a body. Known to drop damaged pieces of diamond armor. Very fast, and small. Spawns in the nether.
The Ghasterburner: has 20 hp, but his body is even more protective. Also known to drop damaged pieces of diamond armor. Rather slow and bulky. Spawns in the nether.
Abyssal Boar: has 225 hp. He is a fast and lethal boar that spawns in the end.
The mod will be available within the next week. Finishing up some last minute bugs.
