The fastest way to get Allied Seals in FFXIV is usually Blue Mage content if you have BLU unlocked, especially the Blue Mage Log and Masked Carnivale, with hunt trains and daily/weekly hunt bills as the main non-BLU fallback. Blue Mage sources can give large seal payouts for first-time and weekly objectives, while hunt bills and ARR A/S-rank hunts provide steady farming over time.

Fastest methods

  • Blue Mage Log. Completing log objectives is the quickest burst farm, and weekly prime targets can award around 400 Allied Seals.
  • Masked Carnivale. Later stages can reward up to 200 seals, so it is strong once you have BLU set up.
  • Daily and weekly hunt bills. These are the reliable baseline source if you do not want to play Blue Mage.
  • ARR A-rank and S-rank hunts. These are the best hunt targets for bigger seal gains, especially when called out by a hunt linkshell or Party Finder train.

What to do first

  1. Unlock and level Blue Mage if you want the fastest seal income.
  1. Clear the Blue Scream of Death quest to open the Blue Mage Log.
  1. Do the weekly BLU log targets and Masked Carnivale stages for the biggest bursts.
  1. If you prefer combat on your main job, do your GC hunt bills every day and join hunt calls for ARR A/S ranks.

Practical route

If you want the most efficient loop, use this order: BLU Log > Masked Carnivale > daily hunts > hunt trains. That gives you the fastest burst income plus a steady fallback if you are not on Blue Mage.

tldr

Blue Mage is the fastest route, hunt bills are the safest routine option, and ARR A/S-rank hunts are the best non-BLU farm.
