Talendox’s Terrifying Tomb

     You conjure an ancient coffin with the appearance of your choice that encases a target creature with a size of large or smaller on a successful ranged spell attack. If the attack hits they take 5D6 necrotic damage and they are trapped in the coffin. At the beginning of their next turned they succeed on a  Wisdom Saving Throw against your spell DC. On a success they breakout of the coffin, but on a fail they take 5D6 necrotic damage, they can’t do anything else on their turn, and they remain in the coffin. They can retry the save at the beginning of their next turn. While in the coffin the target creature is restrained, blinded, and prone. If the target creature takes other damage besides the damage from this spell, the target creature breaks out of the coffin. When you cast this spell at a higher level, it does an additional 1d6 necrotic damage for each level after third.
