Tidal Push

As an action, the wielder can thrust the spear forward to release a powerful surge of water in a 15-foot cone. Each creature in this area must succeed on a DC 14 Strength saving throw or take 2d6 bludgeoning damage and be pushed up to 10 feet away from the wielder. A creature that succeeds on the saving throw takes half damage and is not pushed. This ability embodies the push and pull of ocean tides and can be used again only after the next high tide (typically resetting at midnight).
