Here is are some of the stats on the character I used this on:
- near Max cooldown (63% sheet cooldown, ~95% chance on gear, paragon and passives)
- Long arm of the law passive (doubles the normal 5 second length of all laws to 10 seconds)
- Laws of Valor, Unstoppable force (Half price wrath for duration of spell)
Why do this, you ask?
So it's a 30 second cooldown, but is reduced to 10.96. Since the active skill lasts 5 seconds by default, you get 5 seconds of the law on, and 6 seconds with it off. However with Long arm of the law, you get 10 seconds of law uptime, and only 1 second of downtime. I was never wrath starved when doing this.
