Black Mage

I'm not sure when Fire 2 becomes obsolete but at the latest it definitely stops being used at Lv68 when BLM unlocks Enhanced Umbral Hearts (allowing for 2 Flares in an AF phase). And at Lv72 BLM no longer has to Transpose after Flare because Freeze will cost no MP.

Level 68:
  • Open with Freeze (grants 1 Umbral Heart) and don't use Blizz 3/4 in ice phase during AoE (Freeze grants all the UI stacks and Umbral Hearts needed for AoE)
  • Apply Thunder 4 (use Sharpcast on this for a guaranteed proc)
  • Stop using Fire 2 and only use Flare as the exclusive AoE fire spell
  • Use Triple/Swiftcast on Flares to speed them up along with Ley Lines
  • Can get two Flares out for every fire phase (one consumes heart, second consumes mana)
  • A third Flare can be achieved if Manafont is off cooldown (Flare 1 consume heart, Flare 2 consume mana, then Manafont into the third Flare)
  • If there is a Thundercloud proc, use Thunder 4 right after Transpose while waiting for a mana tick

Level 70:
  • Mix Foul into AoE rotation (likely best to use right after Transpose while waiting for a mana tick)

Level 72:
  • Aspect Mastery means no more Transposing after burning MP on Flares. Use Freeze now to get back into Ice Phase (this does not affect Flare, so continue to use Fire 3 to enter fire phase)

Level 76:
  • Not directly related to AoE, but spam Umbral Soul between trash packs so an opening Freeze can be skipped (can skip an opening Bliz 3/4 during boss fights with this too)
