Darkness Incarnate

You target any number of creatures within a 60ft radius that you can see within 120ft of you. Targeted creatures must make a Constitution saving throw or become cursed for the duration. The curse surges through its targets causing them to charge their nearest threat and make all attacks with advantge. They are forced to embrace the fight side of fight or flight, for the real fear that this curse could kill them.

Cursed creatures take an additional 5d8 necrotic damage any time they take any oher form of damage, either from weapon attacks or other spells, including ones that require a saving throw. The targets of the curse take 2d8 necrotic damage at the top of their turn each round it is active, but can make further consitution saving throws each time they are attacked to take half damage on the additional 5d8.

Upcasting to 9th level increases additional damage by 2d8 in each instance.

If the curse is active on a creature that dies, they cannot be resurrected by anything less than a True Resurrection spell.
