You blow a bubble around any solid, granular, liquid object or creature that weighs 500 pounds or less, causing it to float 4 feet off the ground.when a creature is targeted it must succeed a strenght saving throw or be imprisoned in the bubble. the targeted creature can do the saving throw every turn. the imprisoned creature counts as restrained No matter what the contents of the bubble are, the bubble weighs 10 pounds and can be pushed using an action. Strong winds or effects that would push a creature also push the bubble. The bubble always floats at least 4 feet off the ground, and descends from a fall at a speed of 10 feet per round. As an action, a creature can pierce or attack the bubble with a piercing or slashing attack from the outside causing it to pop and releasing its contents.bludgening damage doesnt pop the bubble instead it pushes the bubble 10 ft. the creature inside the bubble takes only half damage from the attack that pops the bubble
If casted at higher levels the bubble can carry 500 pounds more per level
