Diluvian Wave (5e Spell)
From D&D Wiki
|Casting time:||1 action|
|Range:||Self (30-foot radius)|
You strike the ground, causing flood waters of old to surge from the ground and sweep away your enemies. Each creature you choose within 30 feet of you must succeed on a Constitution saving throw or take 10d8 water damage and be pushed 15 feet away from you and knocked prone. A creature that succeeds on its saving throw takes half as much damage and isn't pushed or knocked prone.
