Tornado

A dark swirling cloud appears, from the cloud a tornado funnel starts coming down to the ground, 20 feet thick which swirls around in a 30-foot radius centred on a point you can see within range. The point must be on ground Until the spell ends, that area is difficult terrain, and any creature that starts its turn there must succeed on a Strength saving throw or take 10d8+15 bludgeoning damage and be pulled 10 feet toward the centre and is knocked prone. On a succeeded save the creature takes half damage.
