All that stuff is situational man. So you can start it out by practicing using Obey > Shadow Flare > Raging Strikes > Bio II > Miasma I > Bio > Fester > Thunder > Contagion > Ruin > Fester (Still in Raging Strikes) > And just repeat. Make sure you let your DOT's fall off, but not by much. Clipping DOTs is just as bad (if not worse) than not having DOTs up. Tri disaster does not belong in a normal rotation. It's simply an AoE bind. My main use is Garuda HM.
