Extract from the Runescape Knowledge Base on the TzHaar Fight Caves: When TzTok-Jad is at half health Whatever your approach, at half health, Yt-HurKots will approach TzTok-Jad and begin to heal him. As hard as it may seem, you must stop fighting the boss and make killing these your highest priority, or else they will restore him to full health and keep returning. To get around these healers, there are generally two approaches. You can either kill these healers, or leave them alive. Either way involves hitting them all once. When you have done this, they will all focus on attacking you, so they will follow you. Here you make your decision. Now they have stopped healing TzTok-Jad, you can either take them aside and kill them off one by one, or continue fighting TzTok-Jad and (hopefully) survive their melee attacks on you. ___________ And there is my proof from Jagex themselves Zybez hasn't been doing their research :P
