Shormy

Evolved from Shadow Spirits, learning ShadowBond in the process. They can be evolved into four types; an Average Level Type that learns SpreadShadow, a Strength Level Type that learns ShadowAttack, a Dexterity Level Type that learns ShadowStep, or a smaller Dexterity Level Type that learns MistForm and becomes a size smaller. They can then further evolve into a Hole Worm, a Void Bringer, or a Shadow Djinn. Note that Shormy have different options for Void Bringer evolution than Shadow Bringers do.

With flying and ShadowTrail, the Shormy is the fastest way to create shadow tiles for a shadow party, quickly making a path for the other units.
