As mentioned in the other thread, I think Aerie should be a Shaman. She's a healer after all and the C/M is a little bit pointless (feel free to disagree).
- no change in stats, she's quite fine as she is
- no more might of avariel
- give her an armour (studded leather of Thorns looks like a fine template and it's so late in the game no-one uses that).
AC 3,
-6 vs missiles
+25% resistance to fire & acid
+2 spells per level (IA standard )
+armour gives her one use of divine intervention
or something like that. Can be forged with aegar's hide & elven stones, 2 scroll of memory boosting and 100.000gp or so?
