The riverine can breathe air and water.
If the riverine fails a saving throw, it can choose to succeed instead.
The riverine makes two Flood Strike attacks.
Melee Attack Roll: +9 to hit, reach 10 ft., one target. Hit: 14 (2d8 + 5) bludgeoning damage plus 10 (3d6) cold damage.
The riverine uses its Whirlpool Step. Immediately after it teleports, each creature within 5 feet of the riverine's destination space takes 5 (1d10) cold damage.
The riverine unleashes a torrent of river water in a 30-foot line that is 5 feet wide. Each creature in that area must make a DC 17 Dexterity saving throw. On a failed save, a creature takes 11 (2d10) bludgeoning damage and is knocked prone. On a successful save, a creature takes half as much damage and isn't knocked prone.
The riverine casts one of the following spells, requiring no material components and using Charisma as the spellcasting ability (spell save DC 17):
At will: control water, fog cloud
1/day: greater restoration
