Copper Cube

The Copper Cube is a small construct enemy in Minecraft Dungeons II with 20 health and a melee attack worth 7 physical damage. With 50 poise and 400 movement speed, it is a middling skirmisher: not fast enough to swarm like zombies, not tough enough to anchor a fight on its own.

Its only listed attack is the straightforward 7-physical melee swing, so it wants to close distance and brawl. The 50 poise means light hits will not always interrupt it, so commit to combos or use heavier weapons when one gets close. In practice it is most dangerous as support during bigger encounters, where it can chip at heroes distracted by a boss.

It is weak to poison damage (+50%) and resists lightning damage (-35%), the same profile as its much larger relative. Poison weapons delete it quickly; lightning builds should look elsewhere. This shared profile is the tell: anything that works on the Copper Monstrosity works on its cubes.

The mob page names no spawn region, but Copper Cubes famously appear when the Copper Monstrosity summons them mid-fight. The Charged Creeper shares the poison weakness, and the Excavator is another construct with a similar brawler role.
