ToME: the Tales of Maj'Eyal

It's really quite odd that you can provoke Slasul into attacking you after taking the trident but then not be able to damage him. Not sure why he's getting invincibility (he also doesn't hurt you, despite being hostile).

Be nice if this were fixed, Treacherous Bastard is enough of a pain to get even without being ripped off for the weapon you basically wasted a prodigy on.

It's intentional. You can only get Treacherous Bastard if you take the prodigy but don't take the weapon.
Otherwise there'd be no incentive to leaving him alive.

Ah, that makes sense, was looking for this.
