Just got raped by Phudor Randoms again. Looks pretty much impossible to me. T_T
Use Defend whenever it's down
Use Heroic Health and Heroic Mana pot. If you suddenly run low on mana, don't hesitate to pop another even though the previous pot effect hasn't finished yet.
Whenever your health is below 50%, use cure
Cast buffs in this order: Haste ->(Defend) Spark -> Spirit Shield -> Protection -> Shadow Veil -> Heartseeker/Arcane Focus -> Regen.
Install STAT script and tick the "Scale gauge lengths based on the highest health points in monsters appeared" box. Now monster's HP bar will be displayed in different length. Focus down monsters with shortest HP bar first
PROFIT!?
