If someone can program the first variant channeling and send me the "user" files, I will program the others as many are very similar. But i can't be myself figure out of to give variable skill bonus.

Unless otherwise stated, bonuses granted by a variant channeling are sacred bonuses if you channel positive energy or profane bonuses if you channel negative energy. If an alternative channeled energy provides a “channel bonus” on rolls or statistics, the bonus is +1, increasing to +2 at cleric level 5 and for every 5 cleric levels thereafter (to a maximum of +5). Likewise, a “channel penalty” is initially –1, increasing to –2 at cleric level 5 and every 5 cleric levels thereafter (to a maximum of –5).
A character who has the channel energy ability from a class other than cleric may use these variant channeling rules if the class’s abilities are tied to serving a deity. For example, paladins can select alternative channeling abilities if they serve a deity, as can oracles with the Life mystery (as they serve many deities), but necromancer wizards cannot.
The following is a list of example portfolios and the variant channeling abilities available to each.
Air/Sky/Wind: Heal—Creatures gain a channel bonus on Acrobatics and Fly checks, saving throws against wind effects, and effects with the air descriptor until the end of your next turn. Harm—Creatures are buffeted with wind until the end of your next turn; this wind gives them a channel penalty on ranged attacks, and their movement is halved if they move toward you.
