This is mostly healing/buffing but very soloable build.
Elec Bolt - 5/5
Must get if you plan on hurting anything.
Concentration - 5/5
Increases MP regen, must have
Lesser Heal - 5/5
Base healing spell
Salvation - 1/5
Rez spell, more ranks reduces the amount of xp lost but meh, only 1 is worth it.
Sleep - 2/5
Great CC, currently doesn't break if damaged by spells which is just dumb. May change on release.
Divine Protection - 5/5
Defense (both short and long range) buff spell, great for parties.
Lesser Party Heal - 5/5
Spell which heals entire party, good to alternate between lesser heal and party heal
Invigoration - ?/5
HP regen buff spell. So far I have 2 ranks, but I don't think it's vital.
Blesses Revelation - ?/5
MP regen buff spell. Max this out, stacks with Concentration.
Moderate Heal - ?/5
At lower ranks it's not that impressive, and there's no DNA for it, but you can alternate between lessers and moderate heals for constant healings.
Other spells I didn't get high enough to get:
Weapon of God: Buff which increases target's Melee attack power. Seems like a pretty good idea.
Blessing of Haste: Increases weapon speed. Also seems like a good idea.
DNA: Moderated Lesser Heal, Strengthened Lesser Heal, Strengthened Concentration. Keep two of them on you (I usually had moderated lesser heal and stregthened concentration while out alone, replaced con dna with moderated lesser heal) until you can get lvl 5 of all 3. I think that happens around lvl 35ish.
