I put 11-15...we're a party of 15-16 level characters (Most of us are 15th and one is 16th). We're playing in FR. Although, lately we've been going through the Iron Fortress module (don't remember the exact name of it) and have been spending most of our time on the plane of War, Archon (sp?) But we should be wrapping that up fairly soon and getting on to something else.
I'm a Barbarian 1/Cleric 6/Runcaster 8. Probably the funnest thing about my character is, due to his having a 10 charisma, he's not exactly the best at turning (he's more of a fighting cleric) So, when he was training...he was never good in the turning studies. He has since gone on and justified to himself that Clangadin wants him to DESTROY evil with his axe...not just move it out of the way. Therefore, he rarely even tries turning attempts. The party has to pretty much goad him into even trying, him muttering to himself about wanting to destroy the damn things...
