Aether Beam

You can open your internal nexus, unleashing a destructive beam of magical energy that emanates from your hand, eyes, or chest. You fire a beam that deals (half your level × 2 − 2)d6 force damage in a 60-foot line and pushes back anyone who stands within. Each creature in the area must attempt a basic Reflex save against your nexus DC. A creature that fails is also pushed back 10 feet (20 feet on a critical failure). The damage increases by 2d6 at 10th level and every 2 levels thereafter. You are no longer overflowing.
