Cotton Cloud

You expel a large wave of magical cotton from your spell focus up to a radius up to 30 feet from the targeted point, this area falls downwards if it's not in contact with fixed structures than can withstand the weight of 10 kg; anything inside the spell's radius does not add onto this weight.

When cast, a creature within the radius may make a strength saving throw and on success may move their strength bonus multiplied by 3 in any direction. A creature that's in the area of the spell when cast is restrained until the spell is dispelled or destroyed; the spell, itself, has 500 hit points and targeting the cotton where it would damage a creature causes both the spell and  the creature to take half damage unless the ability used is targets and area. Furthermore, the cotton is vulnerable to fire damage but immune to bludgeoning, poison and psychic damage. If a creature is to fall onto the area of the spell, it takes no damage from falling.

At Higher Levels. When you cast this spell using a spell slot of 7th spell slot or higher, the hit points are increased by 250 for every spell slot above 6th level.
