Endgame Summoner -- Garuda

If the situation warrants it yes. But why use Ruin II and lose MP when you can use Energy Drain and gain it for more DPS?

I might put it back on later.

Maybe.

You can Ruin 2 and Energy Drain/Fester in the same GCD, since Ruin 2 is instant and Energy Drain/Fester are off the GCD.

Basically:
1. Need to use an off GCD instant in the next 2.5s? Ruin 2
2. Don't need to use an off GCD instant in the next 2.5s? Ruin 1
