Vitality Vial

The Vitality Vial is an Unversed found in Kingdom Hearts Birth by Sleep Final Mix. The player can transform into this Unversed using the exclusive Illusion-V command.

Design
A Vitality Vial's shape resembles that of an hourglass-shaped. It has a turquoise body, which fades to yellow towards its base. Its spherical head has two fin-like protrusions poking out from either side of it. Above its red eyes, which are set in a happy expression, is a triangular, pale gold-colored highlight. Above its head is a noticeably thinner "neck", with a pale gold rim. Its "lid" is turquoise with a pale gold highlight and is topped by a large, light blue gem.

The Vitality Vial's Japanese name name alludes to its appearance, and the goal of the Battle Mission it appears in: to survive for as long as possible.

Strategy
The Vitality Vial can be found exclusively in the Dwarf Woodlands. Terra can confront this enemy in the Underground Waterway.

To begin, stock the player's deck full with Curaga commands. The effects of the Curaga command are a bit more predictable. Make sure the player character has fully levelled up his Magic Haste ability before proceeding, as the encounter with the Vitality Vial is far more survivable this way.

The Vitality Vial will begin by using Draining Mist; it will fill the area with a poisonous mist. This poisonous mist will chop off a fraction of the player character's HP every second. If the player's HP is depleted, the mini-game is ended, but it does not count as a Game Over.

Attacking the Vitality Vial will release clouds of HP, as the report says. The player character may choose to attack it; however, he/she may run the risk of losing more HP if the Vitality Vial chooses to attack. A more evasive, foolproof strategy would be to attack one of the wheels in the Underground Waterway to open a gate, run to the hidden area beyond it, and stay out of the Vitality Vial's reach. The player character's HP will drop consistently each second, but he/she does not run the risk of being attacked, as the Vitality Vial would not consider going through the gate.

Now the player character is safe. When his/her HP drops to the red zone, cast Curaga, wait a few seconds for his/her HP to drop to the red zone, cast Curaga again, and repeat the process for as long as needed to get Illusion-V and/or a three-star rank. Player characters can potentially play this mini-game for an unlimited amount of time by following this strategy, however monotonous it is.
