This effect can be triggered once every 0.2s and can be triggered even if said character is not on the field. When you possess 4 Sigils of Remembrance, all of them will be consumed and all nearby party members will obtain the "Millennial Movement: Farewell Song" effect for 12s. "Millennial Movement: Farewell Song" increases Elemental Mastery by 100~200 and increases ATK by 20~40%. Once this effect is triggered, you will not gain Sigils of Remembrance for 20s. Of the many effects of the "Millennial Movement," buffs of the same type will not stack.
