- /** Spell base damage: Get all master spells
- Base damage modifier: Very very rare. Available from Wizard aa Wisdom line(Brainstorm). Get it, cherish it.
- Int bonus: Past 1200 or so int, you will get a 10% increase in spell damage per 30% increase in int. Look at int tooltip to see the numerical value.
- 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.
- Potency: A straight damage modifier, the more you can get the better. No practical cap.
- 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.
- 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.
- 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.
- Makes the spell cast twice with some limitations.
