Pick up and burn the adds as they spawn (spawn at ~60% heath for Rhitahtyn)
at <30%HP and at <20% HP remaining, the console log will say "Rhitahtyn sas Arvina is readying magitek missiles" There will be almost no time to escape the AE attack when you see the quite large AE circles. There is a small flash explosion right before he casts Magitek Missiles. Look for it the first time, try and avoid it the second time.
One tank should focus on Rhitahtyn (MT) and the other should pick up adds (OT)
Straightforward, heal those who need it.
Between the Magitek Missile attacks it is imperative that healers get everyone's HP up.
Help the Off-tank with adds when they spawn. Focus damage on Rhitahtyn otherwise.
Avoid the Magitek Missile attack.
