Most of Nixak's side adventures (Solo times that nearly killed him) I think I posted in the Mote thread. I didn't post the mind battle that Nixak, Chak-Tha, and Kyrpohius had.
To sum up what happened is that Nixak attacked Chak-Tha's mind and was beat back by not just Chak-Tha but some other mind that had linked with his. Nixak kept attacking and the other mind had no problem thwarting Nixak's attacks.
Then Nixak spent 6 stamina on a last ditch mind duel against Chak-Tha and the other mind and did very well in wrecking some mental havoc until the other mind (It was Kyrophius, the God of Trickery) easily overpowered and nearly killed Nixak. Nixak got to see Kyrophius as as he was overpowered and beat down (very easily I might add).
Also the silver scepter that Nixak had with him started to resonate with power during the battle with Chak-Tha and Nixak had no idea how or any practice with using it.
Looking back I can count four times that Nixak should have died but somehow escaped death. First was when Nixak tried jumping across a river and slipped, hitting his head; he landed face up in the water and drifted down stream. Second was when he came to the rescue of looters in Quera while down to almost no health or stamina in a burning house; tattoo saved him that time. Third time was when he burned 6 stamina on a mind duel with Kyrophius and got his ass handed to him majorly; still had some stamina to keep him alive after that. Fourth time was when Chak-Tha did his finishing move and Nixak took the explosion head first and ended with his life hanging on by one stamina; the amazing party healer saved him with a great roll of the dice.
Yeah, Nixak as escaped death a few times and even mind dueled with two different gods (one was the canopy drake). I have no idea how he is still alive.
