Maelstrom
A vortex of dark water and lightning opens in a 20-foot radius within 60 feet. Each creature in the area makes a Strength saving throw against your spell save DC. On a failure it is pulled 10 feet toward the centre and takes (H + half your level)d8 bludgeoning damage; on a success it takes half damage and is not moved.
A creature that failed the saving throw is Frightened for 1 minute. It repeats a Wisdom saving throw against your spell save DC at the end of each of its turns, ending the condition on a success.
MONSOON. As a lair action at initiative 20, winds buffet the battlefield. Each creature in the area makes a Strength saving throw against your spell save DC or is pushed (H x 10) feet in a direction of your choosing. Colliding with a creature or an obstacle deals 1d10 bludgeoning damage to both. A creature taking cover is unaffected.
