With TH, in around 60% of the games I already get an AoLS without the need for draining pools, so putting it all together, it is pretty infrequent that I need to let Khelavaster die.
These numbers seemed very high to me, so I ran some numbers based on the YAVP forums:
Total winners in YAVP forum is 537. Overall, 229 of those save Khelly, and 318 take treasure hunter.
Of the 229 players who save Khelly, 174 had treasure hunter and 55 did not.
So:
42 percent (229/537) of winners save Khelly.
If you have TH, your odds of saving Khelly are 55 percent (174/318)
If you don't have TH, your odds of saving Khelly are 25 percent (55/219)
This includes saving Khelly by pools. The way I ran the search, this also includes reported non-standard wins (eg. Ironman), that can't possibly save Khelly. It also includes extremely scummed wins (eg. wish engines) that are pretty much guaranteed to save him. But that's a ballpark approximation for your odds of saving him.
Hoping to win with every class, doomed. Archer, Barbarian, Bard, Beastfighter, Druid, Elementalist, Farmer, Fighter, Monk, and ULE Priest down.
