You attempt to curse a creature that you can see within range that has a physical form and has bones inside its body.

It must succeed on a Constitution saving throw.

On a successful save the creature suffers 4d8 necrotic damage and the spell ends.

On a failed save the bones of the affected creature start to throb and pulsate inside his body.

For the duration of the spell, the affected creature's AC is reduced by 2, its movement rate is halved, and it subtracts 1d4 from all its attacks rolls and saving throws.

Additionally, at the start of each of its turns the creature suffers 1d8 points of necrotic damage.
