Do not follow the old Flame Shock–Lava Burst recommendation. The official notes remove Lava Burst, replace it with Call of Thunder, and remove Riptide's initial direct heal.
Elemental spell and mana checks
Call of Thunder adds 5% critical chance to Lightning Bolt and Chain Lightning; it is not another damage button. Chain Lightning has a 2.5-second cast and costs about 225% of comparable-rank Lightning Bolt's Mana. This does not establish an optimal rotation.
Observe mana on single enemies and avoid breaking nearby crowd control. Lightning Overload now has a 10/20/30% proc chance.
Enhancement and healing checks
Stormstrike has a six-second cooldown. Mental Dexterity converts 50/100/150% of Intellect into Attack Power, not directly into spell power as our old article implied. One conversion does not establish gear weights.
Riptide has a twelve-second cooldown and only healing over time. Do not budget an immediate heal when an ally suddenly drops low.
Move totems deliberately
Totemic Projection becomes Totemic Call: it moves totems to your own position with a thirty-second cooldown. Check your position first.
Agree on your role and consult the dungeon directory. This is preparation advice, not a tested build or damage ranking.
