Bless (Fatiguing)
Make a power check as if it were an Aid Another attempt. The subject (who you must touch) gets that bonus to a type of check or save of your choice for a number of times equal to your Wisdom. Alternatively, you can apply half that bonus to *all* of the subject's checks and saves, again for a number of times equal to your Wisdom. No subject may benefit from more than one Blessing at a time; generally only the most recent Blessing applies. You can't Bless yourself.
Time: Full-round action.
Is it balanced? One could replace Wisdom with one's key ability if desired, to make a more generic "buff" spell. Perhaps attack rolls should be forbidden, to avoid stepping on the toes of Enhance Other.
One could also reverse this into a Curse power, I suppose - the subject would get a Will save to resist. Not as flavorful as aaronil's delightful Curse power, but still fun. :)
