Ark Modifications

Resistances and Weaknesses:

Global:
Immune to Dark
Weak to Fairy

Ark's natural defenses protect the bow naturally against certain kinds of influence, so Psychic attacks become neutral to the Bow.

Bonus move: The Bow has Sacred Sword.

Bow Ability: Mode Change

Mode Change - Once per combat, Ark can transform as a free action into its true form, elevating its offense to its full potential. It takes on a humanoid shape, and gains Twisted Power on all of its parts, using the highest values across its pieces. However, in this form all ship parts become attackable no matter what its facing. (Two turn limit, maybe?)

Ark also gets Dark STAB.

Ammy bonus stuff:

Ability: Darkside - At Will, Crew Action. The next attack you make is shifted to Dark type, is automatically a critical hit, and automatically activates secondary effects, but gains Recoil 1/3.

Illusionist: Once, Ammy can use a crew action to change the type of her own or an enemy attack into a common element type (Fairy/Dark/Ice/Water/Flying/Electric/Fire). Ground is not an option you silly goose, stop it.
