Examine the Regal Pawprints (to the north of the previous mission and one level below), at (H-7) of Beaucedine Glacier (S), while in possession of the Umbra Bug to begin the battlefield.
TIP: If you are just completing the previous mission, stay on the same level and head north from the Campaign Arbiter, there will be a hole in the ground by the cliff (H-7). The hole is visible and at the edge overlooking the Regal Pawprints.
Buffs wear upon entry. Time limit is 30 minutes, and experience is not lost upon death. Alter egos may be summoned once inside.
You will fight alongside Lilisette. You have approximately 2 minutes, 30 seconds to prepare before Lilisette will engage Cait Sith Ceithir on her own.
Cait Sith Ceithir will primarily use AoE or single-target black magic, and some enfeebling white magic spells.
If you fail, you will have to get a new Umbra Bug from the Regal Pawprints at the southern Pso'Xja tower at (H-10). You may only obtain an Umbra Bug once per Vana'diel day.
What shocking truth lies behind Cait Sith Ceithir's bold declaration that Atomos will choose the future? The answer must wait! Use the combined power of the surviving Cait Siths to stop the rampant Atomos!
