Brutal Spawners

Brutal Spawners are a type of spawner created in world gen by Deadly World. By default, they have a 10% chance of replacing normal Mob Spawners. The mobs it spawns are exactly like the normal mobs, except with insane potion effects. By default, brutal mobs take 80% less damage, deal 130% more damage, move 30% faster, regenerate health slowly, and are immune to fire and drowning. Brutal spawners always have a chest beneath them, carrying above average loot. The spawn rate, along with the power of the mobs, can be changed in the config file.
