Achak the Wendarin is an Epic Force Support from the Demonspawn faction whose kit operates as a self-sustaining engine. Frostfire Blasts spreads Freeze or HP Burn across all enemies based on each target's individual stat ratio, and the passive Twisted Hunger then converts those debuffs into team-wide healing and Turn Meter gains every time an afflicted enemy takes a turn. This loop rewards multi-enemy content the most: Demonspawn Faction Wars, Spider's Den, and Doom Tower waves including the Sorath encounter. Cannibal Might layers Block Debuffs and Strengthen on all allies simultaneously, giving Achak a meaningful defensive dimension beyond his passive. He pairs naturally with a dedicated HP Burn applier (Tyrant Ixlimor or Sicia work well) to keep the passive firing consistently. Because his debuffs are the cornerstone of his value, investing in Accuracy (220+ for general PvE) is mandatory. He is less suited to single-target boss encounters where Freeze can stall enemy turns and reduce passive triggers.
