[Pocus]

I'm too under the impression that the feature is not polished. Transforming blessed troops into soulless (armored or not) if they are humanoids, and into nothing if they are not (hydras) is not satisfactory.

The perfect thing would be to have something like 10 sub categories, and assign each blessed troop into one of these categories. That would not be perfect, but at least it would allow more precision. Like vestals and valkyries transforming into a female ghost, flagellants as low level undead (but not mindless I think), and beasts into a quadrupedal ghostly animal.
