This time I took Second Mystery - Nature instead of Boundless Healing on Daeran (for 1st mythic ability). My reasoning is that I shouldn't take so much damage that I'll need a heal during combat, and better to invest in preventing damage through Barkskin than in healing. On my last playthrough I turned him into a fulltime healbot but he was kind of taking up a party member slot and wasn't providing any damage, so I was on the fence about his usefulness.
Thoughts, anyone?
I only used Daeran in my Lich playthrough, as Sosiel's Domain Abilities (with Impossible Domain) simply make him a superior choice in p. much all situations. But I did manage to turn him into a respectable damage dealer. Those Bracers you find in Blackwater give spontaneous Spellcasters lots of cool Evocation Spells that Daeran can't get otherwise (Chain Lightning, Stormbolts etc.) and can convert all Energy damage you do into Electricity. If you combine that with Red Salamander Ring, you get a bunch more really good damage Spells (Hellfire Ray, Fire Storm...) whose damage type is also auto-converted into Electricity. Combine that with Ascended Element - Electricity, (Mythic) Spell Penetration, (Mythic) Spell Focus Evocation, Metamagic, Rods and the like and you get a pretty solid nuker.
But you likely won't be getting those Bracers before level 12-13, so he'll have to be relegated to a healbot/buffbot role for almost half the game, unless you figure out a different way to build him.
