For consumables, as a group we should absolutely get
at least one scroll* of Revanence and Revivify. That's like True Res for the price of a 4th and 5th level spell slot, instead of a 9th and a buttload of cash. They won't do my character much good, but they'll probably work for the rest of you.
Here is what I'd like personally: 1xHeal (5), 1x
Guidance of the Avatar(2x1.5=3), 1xArcane Eye(4x1.5=6), 2xCircle of Invisibility(6x1.5=9), 1xSilence(2x1.5=3)
Total: 26
And someone does have some kind of unlimited out-of-combat healing ability for us, don't they? I forget who, but I remember it coming up during the "development phase".
