In the last stage of the Thirsty River mission, players face three teams in three camps. King Khimaar will be in the low area in the center of the map and will keep making defiant statements as seen below. If one of the patrols from any of the three teams sees him, they will attack and kill him. The best way to deal with this is head straight towards the king and kill the party from the right that come forward to kill him.
The bonus of that mission is tied to King Khimaar but is not entirely clear. Literal interpretation of the goal and the King's comments suggest it is to kill all the three teams before his spirit leaves. Other people believe it is to fend them off long enough until his spirit leaves. It is noteworthy that the bonus was broken for sometime (causing players to get the bonus even if he was killed) adding to the confusion.
There are therefore two ways to lose the bonus:
- The king dies
- Ten minutes elapse in the last area and you have not cleared it (he will use the last dialogue entry just before he goes)
- I will never fully rest until the memory of my people is no longer taunted by these filthy creatures...
- My spirits have been weakened by such blashphemy. I must see the Forgotten removed from this place before I slip away...
- In a matter of moments, I shall leave this world for good, never to see my people's resting place cleansed...
