Bubble appears in the 3D versions and is accessible either through Tellah's Recall ability, or through Twincast when Kain is paired up with either Cecil or Rosa. The spell grants the Bubble status on the entire party. It costs 50 MP to use, deducting MP from both users of the Twincast command. The spell is classified as a White Magic spell.
Bubbles is a weak attack that targets all party members, and is used by Clipper.
Bubble is a spell that gives the Bubble status. Bubble doubles the maximum HP of the character it is cast upon. Unlike similar abilities from previous games (the Berserker's Howl in Final Fantasy X-2, for example) it also raises the current HP to reflect the new maximum limit. As an added effect, characters in Bubble status will be immune to Disease.
Bubble can also be cast via the Euclid's Sextant measure. It is a unique weapon in that if the Bubble status takes effect on the target, the target will not receive any damage.
In the original release, it is an Arcane Magick and the License for the spell is Arcane Magick 5 and costs 60 LP to purchase. The spell can be bought from the Muthru Bazaar after attaining a Clan Rank of Ward of Justice and inside the Skyferries between Rabanastre and Nalbina for 3300 gil after obtaining the Treaty-Blade.
In the Zodiac versions, Bubble is instead listed as a Green Magick and unlocked with the Green Magick 3 License. Only the four mage jobs, White Mage, Black Mage, Red Battlemage, Time Battlemage, can cast it. The Bubble Mote can also be used to cast Bubble. It is an extremely rare item but it can also be bought from the Clan Centurio clan provisioner once the player has reached the Order of Ambrosia rank, which can only be achieved by completing the Sky Pirate's Den.
