Hehe true, if the fighter or so dies you can still resurrect him, but if the cleric dies it's over. My cleric is a pretty useless fighter anyway that's why i prefer to keep him in the back.
And those cobol things dunno the real name yuan-ti cobol something, it's in the yuan-ti temple, about 5 or 6 of them, they attacked me in the back when i was fighting of all the rest (mainly a bunch of assassins and some yuan-ti mage) and that really sucked. but in the end i killed them all and my characters were all alive (or back alive
).
