The Esper Ultima uses Holyja as her ultimate attack during the battle against her inside the Great Crystal. The spell does massive holy-elemental damage and causes the Reverse status. The Quickening Concurrence Luminescence is visually similar to this spell.
Holyja is the summon attack of the Esper Zalera. It deals massive non-elemental damage in an area centered around a chosen target. In addition, the Judge of Wings uses it in the two boss fights against her inside the Keep of Forgotten Time.
Holy IV (Holyja in Japanese) is used by Ultima, the High Seraph during her final boss encounter in the Orbonne Monastery raid. The attack summons multiple circular fields underneath random players, attempting to deal unaspected damage to those who fail to run out of the fields in time.
Holyja is the summon ability of the Affechon and Minwu eidolons. The ability deals light-elemental damage to all enemies. Minwu's version costs 2 bars from the summon gauge to use, and Affechon's version requires 3 bars for Aemo to perform.
In the original free-to-play versions, Holyja could be used by the Affechon, Minwu, Hope, and Pumpkin Witch eidolons.
