The Collector

The Collector is one of three Act 2 boss enemies with 282/300 HP. He spawns two Torch Head minions at the start of combat and periodically summons more. His most dangerous attack comes on turn 4 (or turn 3 on ascension), when he casts a move that applies 3 Weak, 3 Vulnerable, and 3 Frail to the player simultaneously — which can cripple both your offensive and defensive output.

The Collector fight prioritizes clearing Torch Head minions quickly to prevent cumulative damage, as they deal consistent damage each turn. His turn-4 triple debuff is the key timing element — either having strong Block ready for that turn or using Artifact to negate one of the debuffs is ideal. The Collector himself has relatively straightforward attacks outside the debuff turn, making the minion management the primary challenge.
