Improved Hammer of Justice

Rank 3/3

Decreases the cooldown of your Hammer of Justice spell by 15 sec.

Doesn't change the damage or healing of any Paladin spell.

Averages, counting crits and misses, for a level 60 Paladin with a typical weapon and no other gear or buffs, against a target your level. Worked out from the game's own data, the same way as the Foresight addon.
