What is Dark super effective against?

Landing a super-effective hit yields a 1.6x damage multiplier. Most elemental types only hit two affinities for bonus damage, giving Dark broader offensive coverage than average.

Elemental advantage depends on the skill used rather than your Aniimo's own typing. Choosing a Dark ability on any Aniimo exploits the elemental weakness of Fire, Grass, and Light targets.

Light Vulnerability and Dark Resistances

Light-element Aniimo resist most damage types and are vulnerable exclusively to the Dark element. Dark abilities provide the only way to gain an elemental damage advantage against them.

Water and Wind Aniimo resist Dark attacks. Striking either of those types drops your damage to a 0.625x modifier.
