[X] No, they might come back with friends, chase down and kill or capture all of them -[X] Iolda will try to direct Mina to block off their escape with a Web spell, if she is able to do so while blinded. Then she will lead Mina to the unconscious iruxi to heal him, along with any others who are injured. The Dark Stalkers will be searched and looted, then killed from a safe range. -[X] If the Web spell succeeds in blocking off their escape or capturing them outright, offer the Dark Creepers a chance to surrender. If they refuse, kill or capture them as time and the situation allows, trying to keep at least one alive for questioning. If the spell fails, Kori, Cob, Gorok, and Warty will try to run them down while the rest of the group readies to move on.
[X] Yes, they had probably been pawns of the monster like the goblins you fought earlier and in any case chasing down a broken band of caligni is an excellent way to get ambushed
