And there we have it.
Lets me put that on my spam key....if I stop dps...it resets in 3 seconds...

Lets me latently keep riptide up, almost to the second, while I sweat through the dps spam.

Hugely mana efficient over what I was doing though....effectively saves me 1400mana every 12 seconds on the shamadama.

:P
