From Complete Champion p 61:
You can temporarily relieve ability damage.
Prerequisite: Ability to cast 2nd-level spells.
Benefit: As long as you have any restoration spell or another conjuration (healing) spell that cures ability damage available to cast, you can confer temporary ability points on yourself or an ally. As a standard action, you can create 2 points + 1 point per level of the highest-level such spell you have available to cast.
These ability points can be applied to any single damaged ability, raising it to a maximum of its starting score. Temporary ability points granted in this way disappear after 10 minutes, returning the subject to its previous damaged state unless some other effect restores the lost ability points first. You can use this effect on the same individual as many times as you wish. As a secondary benefit, you gain a +1 competence bonus to your caster level when casting conjuration (healing) spells.
Are these temporary ability points "lost first" like temporary hp? Can you effectively use this to prevent further damage to that ability by repeated use of this feat? My instincts say no but I can't find a definitive answer anywhere.
