The cleric wizard used his turn to cast wish, and wish that the paladin did not fail her save against that, but the wizard got AOEd by an invisible enemy in the stones. The barbarian and monk were holding back the avatar while the cleric went to revive the wizard, but he was pushed into a time pool by an invisible enemy.
Now the fight was tougher. The monk and barbarian were fighting, but the barbarian was knocked into negative HP. But because of Frenzied berserker, he still kept fighting. The monk backed away because of a promise he made with the barbarian around level 5. The barbarian battled with -200 or so HP, and chunked the avatar each time. Eventually though, his frenzy ran out, and the monk was the last to fight.
The avatar of the dragon stepped over to the monk, who stood up to return to the fight. The avatar was weakened now, and while he might be able to destroy her, it would be a battle hard fought. So he centered himself, and drew in all of his ki. The dragon goddess witnessed what was happening through her avatar that was being controlled, and wept tears of jade. It was a pure sacrifice. No one at the table knew he had this ability until he used it. (besides the GM of course) so we looked at him stunned. The monk sacrificed all that he worked for, he was so close completing his goal, in an effort for the rest of the party to live and complete the quest.
The monk was destroyed. The party restored, but they all knew how. The only thing left of the monk, was when people thought about him, a feeling of pure serenity and peace. The action of pure selflessness was saw by the goddess, and moved her enough to break the control over her avatar long enough to allow the rest of the party to pass into the tower to defeat the lich.
