Undine Overflow (5e Equipment)
From D&D Wiki
Weapon (katana), very rare (requires attunement)
This katana was made from the fangs and claws of a powerful spirits which was only thought to be a myth. Legend say that a piece of undine soul was infuesd with the sword giving it the power of water. This katana can hold a maximum of 5 charges.
Leviathan Tsunami Strike: As an action, you may spend 1 charge to hurl a massive water ball in the shape of a dragon from the blade with a range of 60 feet. You may make a ranged spell attack against the target with a +7 bonus. On a successful hit, you deal 5d10 bludgeoning damage.
Water Vortex: As a bonus action, you may spend 1 charge to summon a mass of water on the ground which appears and swirls in a 60-foot radius centered on a point of your choice within 120 feet of you. The area becomes difficult terrain, and any creature that starts its turn in the radius must succeed a DC 17 Strength saving throw or take 1d10 bludgeoning damage and be pulled 30 feet toward the center. This effect lasts until the start of your next turn.
The katana regains all charges at dawn.
