Just wanting to pick brains for a bit...
My group (lvl 5-6) is about to try to take down a necromancer type, but rather than let them have a straight up fight I am thinking I want to build tension by slowly peeling party members off as they work their way toward his lair. They will then be reunited in a prison and do the standard bust out, grab our gear, kick a$$.
The setting is a fortified castle, they have already gained entry to an empty room and know the rough direction of the necromancer, but will have to sneakily traverse passages and rooms to actually get to him.
A couple thoughts I have had so far:
Paralyze, or stone, one of them.
Drop one in a pit who then is immobilized through a spell and thrown in a cell.
Any other interesting ways to peel off party members one by one? The key is that the character either has to be removed or rendered useless until they are reunited in the prison cell.
Looking forward to hearing people's suggestions!
