Chains of Ilmater (DM)

The crimson bands on your arm animate and project a spectral red chain toward a creature within range. Make a ranged spell attack against the creature to bash it with a thunderous force. On a hit, the target takes 1d8 thunder damage and you can choose to push the creature up to 10 feet from you. You can neither push the creature into danger nor does the movement provoke opportunity attacks.

This spell's damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8).
