Many of the spells have changed in small (and some not so small) ways, and I am unfamiliar with all of them, and I dont have any high level (15+) experience with a caster, so I wanted to post what my plan was for spell selection for an acid spec'ed savant, to see if anyone has some suggestions. I have borrowed from the old Mora Dots build: http://forums.ddo.com/showthread.php?t=309471
Level 1
Nightshield, Hypnotism, Ray of Enfeeblement, Jump
Level 2
Resist Energy, Melf's Acid Arrow, Web, Blur
Level 3
Displacement, Haste, Chain Missile(?), Deep Slumber
Level 4
Stoneskin, Acid Rain, Wall of Fire, Burning Blood
Level 5
Protection from Elements, Break Enchantment, Cloudkill, Symbol of Pain (?)
Level 6
Acid Fog, Disintegrate, Flesh to Stone
Level 7
Prismatic Spray (?), Waves of Exhaustion, Finger of Death
Level 8
Otto's Irresistible Dance, Symbol of Death, Horrid Wilting
Level 9
Meteor Swarm, Mass Hold Monster, Wail of the Banshee
Edit: Exchanged heroism for deep slumber, polar ray for symbol of death (polar ray was my only cold spell, so I was unlikely to spend many ap advancing it), energy drain for mass hold monster: as suggested in posts below.
