Looking through the evocation revisions I thought, I have a few ideas of my own. I'll post them up for you guys to mercilessly tear them a part. With that said these are my basic attempts at fixing direct damage evocation.
Level 0
Ray of Frost At will.
Level 1
Burning Hands As PHB spell but with a maximum of 7d4 points of fire damage.
Magic Missile As PHB spell but inflicts 1d6+1 points of force damage and creates up to nine missiles.
Shocking Grasp As PHB spell but with a maximum of 7d6 points of electrical damage.
Level 2
Scorching Ray As PHB spell but inflicts 7d6 points of fire damage.
Level 3
Fireball As PHB spell but inflicts 1d6 points of fire damage per level (14d6 maximum).
Lightning Bolt As PHB spell but inflicts 1d6 points of electrical damage per level (14d6 maximum).
Level 4
Ice Storm Double damage.
Shout As PHB spell but inflicts 1d6 points of sonic damage per level (14d6 points maximum), twice that amount for crystaline creatures and objects.
Wall of Fire As PHB spell but inflicts three times as much damage.
Level 5
Cone of Cold AS PHB spell but inflicts 1d6 points of cold damage per level (21d6 maximum).
Level 6
Chain Lightning AS PHB spell but inflicts 1d6 points of electrical damage per level (28d6 maximum).
Freezing Sphere AS PHB spell but inflicts 1d6 points of cold damage (1d8 to creatures with the (water) subtype) per level (21d6 (21d8) maximum).
Level 7
Delayed Blast Fireball As PHB spell but inflicts 1d6 points of fire damage per level (28d6 maximum) and ignores artificial fire immunity and resistance.
Level 8
Polar Ray As PHB spell but inflicts 2d6 points of cold damage per level (40d6 points maximum). Plus one ray every four levels (max. 4). Ignores artificial cold immunity and resistance.
Shout, Greater As PHB spell but inflicts 2d6 points of sonic damage per level (35d6 points maximum), twice that amount for crystaline creatures and objects. Ignores artificial sonic immunity and resistance.
Sunburst As PHB spell but inflicts inflicts 2d6 points of positive energy damage per level (35d6 points maximum), twice that amount for undead, molds, slimes and fungi.
Level 9
Meteor Swarm As PHB spell but creates one fireball per two caster levels which inflict 15d6 points of fire damage each. Ignores artificial fire immunity and resistance.
Now I've divided immunities and resistances into two categories. Innate, what you'd get from virture of race or templates and artificial, from spells and magic items.
