Osmose (アスピル, Asupiru?, lit. Aspir), sometimes translated as Psych, Asper, Aspir, or Syphon, is a recurring spell from the series. It is normally associated with Black Magic. The spell absorbs MP from opponents. Many bosses and magic-using enemies will cast Osmose (or something similar) on a player character if they are getting low on MP. It works in reverse or not at all against undead. It has an upgrade in the form of Osmoga.

## Appearances Edit

### Final Fantasy II Edit

Absorbs foes' MP.
—Description

Osmose is a Black Magic spell which transfers MP from one or all enemies to the caster. This is reversed when casting on the undead. The amount of MP transferred depends on the spell level. At a high spell level, Osmose can be incredibly powerful. Any character can learn Osmose by having them use the Osmose Tome (called the Osmose Scroll in the Origins release).

Osmose Tome
Effect Allows the target to learn Osmose when used outside of battle. Casts Osmose VIII on all enemies when used in battle.
Find Cave of Mysidia, Arcane Labyrinth
Drop Wizard

Osmose VIII is exclusive to the Wizard, while Osmose XVI can be cast by Hecteyes and Mega Parasite.

### Final Fantasy IV Edit

Absorbs MP.
—Description

Rydia, Palom, Tellah, and Fusoya can cast Osmose (also known as Psych). It has a casting time of 5 and costs 0 MP. Osmose often only absorbs 1 MP the enemy, as that is the amount of MP most enemies have. A few enemies, like Red Dragon, allow the caster to gain 100 - 150 MP. It can also be cast via using the Lilith Rod as an item in battle.

In the 3D releases, Osmose is much more effective and can drain up to 99 MP from enemies, although some enemies are still immune. It also costs 5 MP to cast instead of 0. In all releases, a good idea is to use Osmose on Cecil and Edge, as they are primarily physical attackers whose magical abilities are negligible, and they thus have little use for MP.

The spell has a spell power of 16 in 2D versions, and 10 in 3D versions, and an accuracy of 100%. Osmose can be cast by Zeromus EG, Golbez, Tiny Mage, and Dark Sage. Zeromus can also cast the spell in the DS version.

## Etymology Edit

Osmosis is the spontaneous net movement of solvent molecules through a semi-permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides. It may also be used to describe a physical process in which any solvent moves across a semipermeable membrane (permeable to the solvent, but not the solute) separating two solutions of different concentrations.

The original name, "Asupiru" (or "Aspir"), is likely an abbreviation of the word "aspirate," meaning "to draw in by suction," or the French version of that word, "aspirer," with the same meaning.
