Walloping Wave

2-point evocation (water)
Casting time:	action
Range:	30 feet
Components:	V, S
Duration:	instant

An ice-cold wave of salt water appears and rushes out from you before crashing into a creature in range that you can see, then dissipates. There must be a clear 5-foot-wide line between you and the target, otherwise the wave instead crashes into the first object or creature in its path, turning this obstruction into the target instead.
 The target becomes soaked and must make a Strength saving throw. A creature larger than Large size has advantage on this save. On a failure, the target takes 4d10 cold damage and is pushed 10 feet away directly away from you. On a success, the target takes half as much damage and isn't pushed.
 Upcast. You can upcast this spell by expending extra spell points when you cast it. This spell's damage increases by 1d10 for each extra magic point.
