You can cast this spell on [[Statuette|Statuettes of <deity>]], but it has no effect on [[channeling]] skill gain.
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_(container)|fountain]], the refilling of the container does not affect the spell.
This spell decays with the use of the item.
