I have run into some issues with Maeri, my C/T, in the party I'm playing now. Her base THAC0 is 15, which isn't great, and she only gets bonuses for her weapon proficiency and from the +2 hammer itself. Which means that in most battles, she is swinging and missing a lot. I do generally have her use DUHM before going into battle, which definitely helps, but she is still having issues.
Enough that it concerns me to do the druid grove quest, as I'm not sure she could beat Faldorn in one on one combat.
I'm also worried about trying to do Rasaad's quest, which I would normally do at this point, because Rasaad is pointless still, and for reasons I can't fathom, rather than Rasaad doing the quest, the PC does it instead. In the past, my mage/sorcerer PCs could summon creatures to help with that one room and remain invisible until the shadows were weakened enough. (Though, depending on level, her turn undead might mitigate that problem)
Part of the issue is that she is a multi-class, and only just now a level 9 cleric (while Imoen just hit level 11 mage), but surely there is some way to get her melee skills up to par? Or, am I just playing her character wrong? (Can you even backstab with a hammer?)
