Greetings.

Some of you have already posted the information that was on the Japanese forums, but here it is again, officially.

Required number of items
As a result of adjustments to match the trial difficulty, the below are the current numbers that are planned for the stage 1 version of the weapon upgrades.
  • Relic Weapons: 5 items
  • Mythic Weapons: 3 items
  • Empyrean Weapons: 60 items

※As we are currently carefully looking into the number of items required for stage 2, we will let you know the specifics once the information is available.
