Natural Evoker (3.5e Alternate Class Feature)
From D&D Wiki
You have discovered an ability that manifests your natural talent when it comes to destruction.
Replaces: If you select this class feature you do not gain a familiar and you can cast and know one less spell of each level.
Benefit: Starting at first level, you gain a ranged touch attack with a range of (100'+10'per Lvl) that deals 1d10+Cha energy damage of a single energy type (Acid, Cold, Electric,Fire or Sonic). This damage increases by 1d10 at third level and every three levels thereafter, and at 5th, 10th, 15th and 20th levels, you may choose an additional energy type that this attack can deal, though you can only use a single energy type per attack.
