I've figured out what I've been doing wrong. Back before we took such a long break, I had been resolving rounds in nice, bite-sized chunks (a few PCs and BGs at a time), but since we started up again, I've tried to do it all at once, and it's just plain intimidating, making me constantly think "I don't have time, I'll do it later!" which isn't happening. So I'll go back to splitting it up.
That said, for THIS fight, it's done. (I'm sorry it became a bit anticlimactic, after so long a wait, but you did SOOO much damage to Tamanier while I wasn't looking!)
Besides, this gives us the ability to move along.
