Cato's Water Bubble

You create a durable bubble that keeps the caster off the ground in a cushy bubble-like chair. This bubble allows those with tails instead of legs to move with more ease on land. The bubble can hover 1 foot off the ground and move in any direction at the caster's dominant movement speed. The bubble lasts until it's dispelled. 

The sea glass and pearl are reusable spell components, however, the water used for the spell is consumed each time the spell is cast. If the spell caster is knocked unconscious whilst sitting in the bubble, the bubble will remain but stay motionless until the caster regains consciousness. 

Should the spell be dispelled, the bubble will disappear, leaving the caster floundering.
