My character is going to be focused on two shticks - mass healing (via feats from Complete Divine and Complete Mage) and ranged combat (via my Eldritch Blast). I can wear light armor and use all simple weapons, plus rapier and short sword (and hand crossbow), so I won't be adverse to stepping up if needs be; my low-ish HP (8d6+4d8) means I won't be taking on Big Bads in melee but may be able to help with multiple weaker foes.
Feats I've chosen?
Touch of Healing (reserve feat): I can auto-heal everyone up to half their HP for free outside of combat.
Sacred Healing: gives everyone fast healing 3 for a bunch of rounds with a Turn (Turn Undead) burn.
Extra Turning: more Turn burnin'
Reach Spell: cast healing and other touch spells on anyone within 30' without needing to touch them.
Precise Shot: no -4 for shooting into melee for me (even with Touch attacks, -4 is gross; I get Point Blank Shot for free with the Elf domain).
And, as I mentioned before, I can Turn burn to convert my EB into a 5d6 healing ray.
Comments, suggestions?
