SubTwin

SubTwin is the spawned duplicate created by a Twin elite buff on a boss. This boss variant has 50% of the original boss's maximum health and is scaled to 75% size. It retains the full ability kit and attack patterns of the original boss. The SubTwin cannot spawn its own twin, preventing infinite duplication. It functions as a complete second boss entity with reduced health but identical threat level per action.

A SubTwin boss is far more dangerous than a SubTwin regular enemy because boss abilities tend to be more powerful and cover larger areas. Two copies of a boss casting area-denial abilities or charging attacks can overwhelm your team's ability to dodge and position safely. The split health pool means neither copy is particularly tanky on its own, but the doubled action economy means your team takes roughly twice the punishment per round.

Focus fire one copy down immediately to restore the fight to a single-boss encounter. The SubTwin's 50% health makes it the natural first target since it dies faster. Area-of-effect damage that can hit both copies simultaneously is extremely valuable in the opening turns. Do not split your team's attention between both copies unless you can kill them at roughly the same time. Coordinate your cats to burn down the SubTwin, then handle the original Twin boss with your full team's attention.
