Preservation

Skill Requirement: Low

Mana requirement: Depends on the size of the target

A spell that preserves the freshness of its target. It prevents the oxidation, desiccation and decomposition of its target. Items with this spell cast on them can be dried in the sun while maintaining the freshness of their organic components.

However, these items do not become indestructible, so it is still possible to burn items with this spell cast on them using fire.

Also, living creatures cannot be targeted by this spell, so it does not prevent aging. It does prevent hair from becoming disheveled, however.

    Freshness Restoration

Skill Requirement: Medium

Mana requirement: Depends on the state of freshness that is being restored

A spell that restores the freshness of a target. It restores decomposed organic substances to their original state, but it does not restore damage caused by decomposition.

Also, if this spell is used on a mummy, it has no effect unless water is applied at the same time.

If this is used on fermented food, it reverses the fermentation process.

    Decomposition, Fermentation

Skill Requirement: Low

Mana requirement: Depends on the degree of decomposition and fermentation

Spells that decompose or ferment their target. On Earth and in Origin, there are no strict differences between the phenomena of decomposition and fermentation other than that fermentation is useful to humans, so strictly speaking, these two are essentially the same spell.

The difference is that Decomposition has no limits to the time duration and effect of the decomposition it causes on its target, while Fermentation limits the duration of its effect to a point where it results in something that is useful to humans.

If Decomposition is used on a barrel of fresh miso, unless the duration is limited, even the barrel itself will decompose and disintegrate, never mind the soya beans. But no matter how long Fermentation is cast on the same barrel of fresh miso, the resulting product will be fermented miso.

Because of this, the use of Fermentation is limited to things like creating fermented foods from fresh ingredients and compost from waste. However, if used on ingredients for sake, the environment must be adjusted accordingly and limits must be placed, otherwise, vinegar will be produced.

Also, Decomposition has no effects on living creatures and inanimate objects that do not decompose.
