This warhammer is forged from sea-silver and fossilised coral. When it swings, it throws an arc of water droplets in its path. You gain a +1 bonus to attack and damage rolls.

The Tidecaller's Maul has 4 charges and regains all expended charges daily at dawn. While attuned, you can expend the charges in the following ways:

Overhead Wave: When you make a melee weapon attack with this weapon, you can expend 1 charge to leap up to 10 feet toward the target without expending movement. If the attack hits, the target takes an additional 1d8 bludgeoning damage and must succeed on a DC 14 Strength saving throw or be knocked prone.

Erupting Geyser: As an action, you can expend 2 charges to slam the maul into the ground and cause a geyser to erupt in a 10-foot square within 30 feet of you. Each creature in that area, up to a height of 100 feet, must make a DC 14 Dexterity saving throw. On a failed save, a creature takes 2d8 fire damage and 2d8 bludgeoning damage and is launched 20 feet straight upward. On a successful save, the creature takes half as much damage and isn’t launched.

Water Cannon: As an action, you can expend 3 charges to begin channeling water vapor into the maul. If you have taken 15 or fewer hit points of damage by the start of your next turn, you can make a special ranged weapon attack using the maul. The target must be within 40 feet of you and visible. On a hit, the target takes 8d8 bludgeoning damage and is pushed 10 feet away from you.

Proficiency with a Warhammer allows you to add your proficiency bonus to the attack roll for any attack you make with it.

Notes: Versatile, Push
