You can also cast this on water (and maybe other liquids inside containers). The liquid must be dragged between containers to retain the spell effects. When cast on water within a [[well]] or a [[fountain]], the refilling of the container does not affect the spell.
This spell does not apply to characteristic gains.
When cast on a metal lump, the enchanted lump can be combined with unenchanted lumps to maintain the enchant. Activate the enchanted lump, and combine with others.
