Timosha's Torrential Terrain

Until the spell ends, torrential rain falls and hurricane like wind blows in a 100-foot-tall cylinder with a 60-foot radius centered on a point you choose within range. The area is heavily obscured, and exposed flames in the area are doused.

The ground in the area is covered with a 1-foot pool of water, making it difficult terrain. When a creature enters the spell's area for the first time on a turn or starts its turn there, it must make a Strength saving throw. On a failed save, it falls prone. If a creature is knocked prone it is then lifted by a gust of hurricane like wind and is battered by torrential conditions taking 1d6 bludgeoning damage for each turn it is trapped in the spells radius and is then considered restrained. Also for each turn after being knocked prone you will be thrusted 20-foot upwards into the 100-foot-tall cylinder. Once you reach the top you will then be thrust out of the cylinder 65-foot in a random direction horizontal to the spells radius.

If a creature starts its turn in the spell's area and is concentrating on a spell, the creature must make a successful Constitution saving throw against your spell save DC or lose concentration.
