bobo485: carried out my task to take Slaan into vault to rescue his fellow lizard, cleared out all ot the undead and area boss. Reached captive lilzaards but Slaan will only respond with his 'no tak now' dialogue, tried twice same result.
Tried to get Slann killed by wolves in order to remove map from his remains, but AI will not let him die.
Seems to no way for me to kill him. Went back to previous area, Slaan still with me.....help

Would it help if I backtracked in the campaign and started again? could I face doing that

Damien.01: You have to talk to the lizard captive's sergeant in the crypt.
