I reloaded and tried the balcony myself. Step to the parapet, ranged attack, step back. rinse & repeat. Once you're set up, all but 0 damage (well, four of them came up on the balcony, and one tossed a nasty) Nice thing is you can step inside if you need heals and/or things start to go seriously bad for some reason
Cheers, and thanks for an even
better strategy
In case you missed it, just behind the fountain is a breakable wall into the temple
