The Japanese units are seemingly unaffected by some Blessings in Celestial Challenge.
Here I have selected the following blessings:
1. Gaia’s Lashing Roots (Hero Area damage +3): Which is lacking on both Miko, Onna-Musha (Pictured) and all other Heroes.
2. Poseidon’s Rushing Tides (Hero Speed +30%): Also lacking on both Miko, Onna-Musha (Pictured) and all other Heroes.
3. Athena’s Aegis Infantry (Infantry HP +25%): This one DOES affect the Onna-Musha (Base HP 200→250)
Curiously enough the two first mentioned Blessings do work in Arena of the Gods. But worth noting:
Miko doesn’t state that it get Area damage, but I don’t think Atlantean Hero Citizen states it either, but I think they gave the impression they had it during an enemy cast of Fimbulwinter long ago? (I’m a bit uncertain on this one)
Onna-Musha didn’t get it on their Special Attack (Naginatajutsu) despite getting it on their normal attacks in Arena of the Gods.
I played first the Celestial Challenge, then Arena of the Gods and then reconfirmed playing the Celestial Challenge again, used stated Blessings.
