This spell creates a tough, flexible bubble that is large enough to accommodate several passengers and which can move through the water under its own power, as directed by its caster. Passengers may enter or leave the bubble by simply pushing themselves slowly through its surface, although the spell's caster has control over who is allowed to enter. Once a passenger is inside however, he has no ability to eject them. When fully immersed Bubble absorbs oxygen from the water around it and releases carbon dioxide back, allowing those within to breath normally.

Although it is fairly resilient, sufficient damage inflicted all at once will burst it and end the spell. The bubble is strong enough to count as bonus armour for those inside, but attacks made against passengers from outside apply their damage to both their target and the bubble itself. Attacks made from inside against targets outside follow the same rules, granting the bubble's bonus armour to their target and inflicting damage on the bubble. When considering damage to the bubble itself use only it's Durability score and ignore its Surface Armour, however blunt attacks are not effective against it – Very Blunt damage has a -2 DC against the bubble and Blunt has -1 DC.
