Just writing to thank you all for the tips last week. I re-ran the fight, not with my Wizard, but with a new Fighter (figured I'd test strats with something that had more survivability). Sneaking up the right-hand side was key, and to be honest, it never occurred to me that you could even do that. I also tossed a void bulb at the first brain to aggro on me, and that seemed to have bought me an extra round. I didn't have to use the balcony trick this time, but it's good to know there's an exit strategy for my squishy Wizard.
I'll probably try the Grease trick next time, but I doubt it will slow down the buggers much. They make their Dex saves against Shadowheart's Sacred Flame too often for my comfort, so I figure they'll just dance across the grease as well, but I might try to barbecue them when they're in the thick of it. Fire solves most problems, after all.
Anyway, thanks again!
