Minecraft Dungeons:Powerful Mobs

A mini boss is a mob that is stronger than most mobs. Mini bosses use bossbars, like bosses, although their bossbars are smaller. The mobs in bold can also spawn as bosses. The chance of a mob to be replace by a mini boss is 1%. There are mobs that can be defined as mini bosses, but don't use a bossbar, like the rampart captain.
