  1610. Base damage modifier: Very very rare. Available from Wizard aa Wisdom line(Brainstorm). Get it, cherish it.

  1612. Skill bonus: Past skill cap, 100 points skill is worth 2% increase in minimum spell damage, which translates to 1% overall increase. Looks at the skill that the spell uses, for wizards mostly disruption. Cap is 6.5*level.
  1613. Potency: A straight damage modifier, the more you can get the better. No practical cap.
  1614. Ability modifier: A straight damage modifier. Limited to 50% of the spell base damage, but for a wizard this usually has little consequence. However note that this is not affected by Potency.
  1615. Crit bonus: A straight damage modifier, the more you can get the better. No practical cap. Wizards got 50% intrinsic Crit Bonus that does not show up in the stat window, just add 50 to stat value for calculations.
  1616. Spell double cast: A straight damage modifier, the more you can get the better. You won't be able to get very much of this.
