Creeper

The Creeper is the classic exploding enemy of Minecraft Dungeons II, a green stalker with 17 health and a proximity explosion worth 70 blast damage. It needs no introduction: get close, it flashes, and everything nearby takes a devastating hit that outclasses almost every other regular mob's damage.

Its only listed attack is that proximity area blast. There is no melee or ranged alternative, which makes the counterplay binary: kill it from range or keep moving so it cannot close. At 500 movement speed it is persistent but outrunnable, and its 36 poise means a steady stream of hits can keep it staggered before it detonates.

The mob page lists no elemental weaknesses or resistances for the Creeper, so bring whatever damage you like; there is no wrong answer and no bonus to chase. The real defense is awareness: never let one walk into the middle of your group, and finish it before it finishes you.

It is fought primarily in the Frozen Highlands, with additional listings in Honeycomb Fields and the Howling Woods. The Charged Creeper is its deadlier electrified cousin at 75 blast, the Charred is another heavy hitter to respect, and the Bee is a fellow small hostile.
