It isnt as easy as ppl saying as its a 2 button rotation the main reason its that simple is cause u have to watch your mana bar like a hawk

Acronyms
ABxInf = Arcane Blast x Infinity
AB4MBAM = 4 Stacked Arcane Blast + Arcane Missiles
AB4AB = 4 Stacked Arcane Blast + Arcane Barrage
FOAM = Flame Orb Arcane Missile Spam



It consists of 2 Phases

1st Phase(Burn Phase)
Either of the Following
1a) Is Evocation Off? Is Cooldowns(Arcane Power, Mana gem) Ready? Is Trinket Procs + Potion Ready?
1b) Is the Boss going to Die Soon? *Need Proper Prediction or u will run oom for the fight* best chance is unless its halfus, its around 5-7%.. start burning if u still have full mana

Use ABxInf until u reach 30% because of your Mage Armor + Replen in raid so by the time your evocate finish channelling u will have 100%

Dont worry if ur mana % is all fucked up cause of int procs, cause the int that u gain outweighs the mastery percentage..

2nd Phase(Mana Conserve Phase)

I Check for the following
2a) Is Flame Orb up? if so, Force mana below 80% and use FOAM, it will bring u back to 100% by the time it ends
2b) Is Arcane Missiles up? If so, do u have clearcasting? If so, force off all Arcane Potency, then use AB4MBAM

If none of the above
2c) Keep Doing AB4MBAM until your evocate + trinkets line up then u go back to 1st phase.. rinse and repeat
