Vortex

You create a swirling vortex of magenta, purple, pink and black. Pulling everyone (not including you) around you into this vortex make a DC strength check to Avoid being pulled in. When a creature is pulled in they take 7d8 fire damage and 7d8 force damage they are also restrained and take this damage at the end of that creature’s turn lasting for the duration. The creature/creature’s can take the saving throw again to avoid taking most of this damage.
