Black Mage (BLM) Cross-class skills discussion

Well, you got some slim pickings here.

Ruin and Hawks Eye are useless to you. There’s no debating this.

Physick is arguably your best cross class skill. Infinite cures with Umbral Ice is never bad in a bind.

Virus is a welcome debuff. Reducing damage, parry and block strength (and chance). Admittedly, this one isn’t used very often even by ACN’s SCH’s and SMN’s… I wonder why.

Eye for an Eye – Deceptively useful. The availability of this skill amongst many classes rewards an organized group by taking turns putting this buff on the tank.

Quelling Strikes – Ah, the best one you can get. If you like opening with Thunder -> Fire, you’re going to need this to offset the threat.

Raging Strikes – An obvious choice. Only use it when you’re in your Fire phase.

Well, since you can get seven, and 2 are garbage, I guess the choice is obvious…

Ideal Black Mage (BLM) Cross-class progression

  1. Thaumaturge to 15 for: Unlocking other classes.
  2. Arcanist to for: Physick.
  3. Archer to 4 for: Raging Strikes.
  4. Thaumaturge to 30 for: BLM Requirement.
  5. Archer to 15 for: BLM Requirement (Raging Strikes).
  6. Black Mage to 50 for: Maximum level.
  7. Archer to to 34 for: Quelling Strikes.
  8. Arcanist to 34 for: Eye for an Eye (All Cross-class skills obtained)

Getting Physick (Arcanist 4) is really really really (really) worth it, and is probably your most important cross-class skill aside from Quelling Strikes.


  • Black Mages use skills from: Archer and Arcanist.
  • Physick. Get this. Use it. Profit. Combine it with Swiftcast if you like!?
  • Eye for an Eye is a decent raid helping skill. Also, get used to timing Quelling Strikes.
  • Best Black Mage Cross-Class skills:
    Physick, Raging Strikes, Quelling Strikes, Virus, Eye for an Eye.

    1. Simply go to ul’dah and get the THM class once you’re level 15 (might as well get the level requirement for black mage). Then once you’re THM 30, make sure you’ve completed all the class quests you have (till 15 for archer, till 30 for THM), then the quest to be black mage should unlock.

          1. They only advice I can give you is to finish all the quests you have in that image. You’re supposed to receive an airship pass to be able to travel to other cities.

  1. Apocatastasis is another good one when fighting enemies that use elemental moves

    I only cast it on the tank via the “target’s target” so I never have to deselect what i’m fighting

    /macroicon Apocatastasis
