Tidal Surge — Cone

You create an onrushing surge of water 10 feet high in either a 30-foot cone or a 60-foot line that deals 1d10 points of bludgeoning damage for every 2 caster levels you have (maximum 10d10 at 20th level). In addition to taking damage, creatures that fail their Reflex saves are pushed 1d4×5 feet away from you and are knocked prone. Magical effects with fire descriptor on targets in the area of a tidal surge and similar area effects in the selected point are affected as if you had cast dispel magic.
