Bar 2: Same as above
Head: v16 Valkyn Skoria Light Infused
Chest: v16 Julianos Heavy Infused
Shoulder: v16 Valkyn Skoria Light Divines
Hands: v16 Julianos Light Divines
Waist: v16 Julianos Light Divines

Feet: v16 Julianos Light Divines
Neck: v16 Willpower Healthy
Ring 1: v16 Willpower Arcane

Heavy chest and medium legs are technically the best pieces to be heavy and medium, but it all depends on your Skoria roll. Just make sure in the end you have 1 heavy 1 medium 5 light. (i.e. if you get a medium helm and heavy shoulder just make chest and legs light)

Max magicka glyphs on armor, spell power glyphs on jewelry and fire glyphs on staff(unless it's a maelstrom staff)

Rotation: Always keep Sea of Flames toggled, but make sure you only use it after you've fully buffed(food and entropy) then keep annulment up for survivability. Apply your dots in this order: Entropy > Engulfing Flames > Scalding Rune > Burning Embers then apply Elemental Drain and Igneous Weapons, switch back to your main bar, and heavy weave with Molten Whip. As far as ultimates go, never use Shooting Star. When Standard is up, fit it into your dot rotation like this: Entropy > Standard > Entropy > Engulfing Flames > Rune > Embers > Igneous Weapons > Heavy Weave/Molten Whip until repeat, which is every 12 seconds or so. Reapply Drain every other rotation.
