I recently got my capped Cleric flagged/booted for ToD, though I've run it maybe 4 times on my capped Ranger, so I have a little experience for what happens in the various parts (haven't been in a group that's done the optional yet, though). From what I've seen, it looks like the part with the Judge/Jailer would be the most hectic/toughest to handle from a healing perspective. It seems you might be able to heal a big part of the Shadow room with Burst and scrolls (assuming the guy kiting is doing a good job), and the end fight as well? I haven't had time so far to pay close attention to the healers' SP bars, so not sure just how SP intensive this one is. I haven't heard them complain about having to chug 15 pots or anything like that, but that doesn't mean they didn't... (This all assumes lag doesn't rear it's ugly head, of course.)
Thanks in advance for any tips
