Notes

Taking into account only spell damage, cast time and points in Improved Fireball, the following equation computes the DPS of Fireball. In this equation, d is the amount of Fire spell damage, B is the base Fireball damage, and X is the number of points in Improved Fireball.

(d + B)/(3.5 - 0.1*X)

Solving this equation for zero points and five points in the talent gives:

(d + B)/3.5  @ 0/5 Imp. Fireball
(d + B)/3.0  @ 5/5 Imp. Fireball

Example

The following example uses [Fireball] rank 13, with a 3.5 second cast, 633 - 805 damage done, and a base spell damage coefficient of 1.0 without talents.

(633 + 805) / 2 = 719

On average, this is 719 average damage done per hit.

719 / 3.5 = 205.4

Dividing by cast time, the spell does 205.4 Damage Per Second. With 5 points in the talent, but with no spell damage:

719 / 3.0 = 239.7

With no spell damage, the talent gives a boost to Fireball Damage Per Second of 34.3. Add in 500 spell damage:

719 + (500 * 1.0) = 1219

The average cast now does 1219 damage per hit without the talent.

1219 / 3.5 = 348.3

The spell now does 348.3 Damage Per Second without the talent. Now take 5/5 Improved Fireball:

719 + 500 = 1219

The average cast now does 1219 damage per hit.

1219 / 3.0 = 406.33

Fully talented, the example gives 406.33 Damage Per Second, over 348.3 without the talent, a Damage Per Second increase of 58.033 if you have 500 spell damage.

Patch changes

As of Patch 2.0.6 each rank of "Improved Fireball" now reduces Fireball's spell damage coefficient by 2%. Prior to this patch, the talent only reduced cast time.

In patch 2.3 this damage tax was removed.
