Spirit of Darkness, with very low health is the most fragile character in physical world. But it more than makes up for it with deadly power in the spirit world. Spirit of Darkness' abilities in physical world focus on empowering its next spirit attack with extra damage or targets. It has some strong physical abilities one of which is stronger the more the character has moved in the spirit world. Additionally its passive gives
a chance to add an extra target to next attack immediately after switching between realms. This means that Spirit of Darkness will never stay long in one realm. Its strongest ability empowers all subsequent spirit attacks for a couple of turns - including chanelled attacks.
SPIRIT OF DARKNESS
Spirit of Darkness can evolve to gain even more advantages from shifting between the realms. It can switch places with another ally, allowing for some interesting combos, it can gain more from its passive when close to multiple enemies. In spirit world Darkness can sacrifice its channelled abilities to support allies.
Gameplay with Spirit of Darkness will be a dance between the realms, using the benefits of switching between forms and maximising the effects in the opposite world. In physical form Darkness might feel underpowered, but once some of the enemy spirits are weakened, with Darkness in your party, they will just start disappearing around you.
