== Source ==
'''Improved Frostbolt''' is a [[mage]] talent that reduces casting time of the [[Frostbolt]] spell by 0.1 seconds per rank, up to 0.5 seconds at rank 5. As a side effect, this talent also decreases the [[spell damage]] coefficient for Frostbolt by 2% per rank, though this is not listed on the talent description. This talent significantly increases the DPS of Frostbolt, making it a key talent in Frost specs that rely on it as a primary damage spell. The spell damage coefficient penalty reduces damage per ''cast'' for higher level mages that have a lot of spell damage gear. Despite the penalty, the talent always increases damage per ''second'' regardless of how much spell damage the mage has. Mages often refer to this penalty as the "damage tax."

[[Frostbolt]]'s [[spell damage]] coefficient is normally 81.4% of total Frost spell damage. The spell damage penalty from this talent is multiplicative, and is applied after the additive spell damage bonus of [[Empowered Frostbolt]]. With 5 points in Improved Frostbolt, the coefficient is (81.4% * 90%), or 73.3%. The following formula will compute the spell damage coefficient for Frostbolt with points in both talents, where X is the number of points in Improved Frostbolt and Y is the number of points in Empowered frostbolt:

Note that the cast time reduction does not affect the base 81.4% damage coefficient; it is still based on a cast time of 3.0 seconds. Taking into account only spell damage, cast time and points in Improved Frostbolt, the following equation computes the [[DPS]] of Frostbolt. In this equation, d is the amount of Frost spell damage, B is the base Frostbolt damage, and X is the number of points in Improved Frostbolt.

[[Category:Halls of Origination items]]
 
<pre>(.95(3.0/3.5)(1.0-0.02X)*d + B)/(3.0 - 0.1*X)</pre>
 
 
Solving this equation for zero points and five points in the talent gives:
 
 
<pre>0.2714*d + (B/3.0) @ 0/5 Imp. Frostbolt
 
0.2931*d + (B/2.5) @ 5/5 Imp. Frostbolt</pre>
 
 
These two examples illustrate that before talents, each point of spell damage adds 0.2714 DPS to Frostbolt, while after talents each point adds 0.2931 DPS, meaning that Improved Frostbolt is an overall DPS improvement regardless of the spell damage penalty. For more details on Frostbolt damage equations, see the main [[Frostbolt]] article.
 
 
==Past changes==
 
As of [[Patch 2.0.6]] each rank of "Improved Frostbolt" now reduces Frostbolt's spell damage coefficient by 2%. Prior to this patch, the talent only reduced cast time.
 
 
==Future changes==
 
In [[patch 2.3]] as stated by [[Drysc]] the damage tax will be "Obliterated."<ref>{{ref web|url=http://forums.worldofwarcraft.com/thread.html?topicId=1778587218#16|date=09-26-2007|title=Re: What is in store for 2.3?
