ToME: the Tales of Maj'Eyal

I've fought Rak'Shor Cultist in Shadow Crypt (3) twice now, once in 1.0.3 with a Cornac Archmage and once in 1.0.4. with a Skeleton Sun Paladin. Both times he did not summon the shade you're required to kill to unlock Doomed. This second time, I got him down to around 30%, then idled near him for, well, a long time, long enough for him to get back up to 80% hp, yet still, no summon.

I am having the same problem. I have killed the Rak'Shor Cultist in the crypt in 1.04 with a Cornac Summoner, a human oozemancer, a skeleton reaver, and a Yeek solipsist without ever seeing my clone. I have killed him fast and I have killed him very slow.

The cultist is bugged and does not summon the Shade unless you have some way of turning off his Bone Shield (Corrupted Negation, Disperse Magic, the Spellhunt Remnants, etc). The bug will be fixed whenever the next release comes out (it's already fixed in the repository).
