Ravine - giant crack in the ground. Sounds exactly like the place the armies of the Nether would crawl out of. We only managed to rescue a few people, and they all said the same thing: they were being taken towards the Ravine. Better keep on our tows, I feel like the guardian of this place wouldn't be the weak type.
Tier 4 Artillery: The Grief-inator
We've let out a few criminal rogues on the condition that they could build us a truly powerful weapon. They did not disappoint.
Super TNT: launches an ultra-powerful bundle of explosive death at enemies
Hot Soup: a nice flow of lava will slow and melt any enemy that dares get in the radius of this tower
The Boss: Xa-Thul
The legendary king of the zombies, you'd have to be a fool to dare challenge him.
Phase 1: area attack, rider; no armor; no resistance
Rider: rides a zombie horse and will speed up if not engaged in combat for 5 seconds
Phase 2: area attack, summon, roar; no armor; no resistance
Summon: calls 5-8 zombies around himself
Roar: increases the speed and damage of all zombies ( excluding himself)
