Yeah, my bad, poorly phrased post. So to make sure I understand this correctly:
I am creating a Melnibonean Priest who has the rank of Citizen of Yagala with 5 points of POW dedicated to Terhali. He has 2 compulsions, Demonic Fervour and Lust for Terhali. He has elected to take the second gift available due to his rank. I've chosen Divine Training that I've bought with 3 points of POW and applied to Language (High Speech) and *edit* Lore Terhali *edit* both of which are now 100%. The other gift was Witch Sight at it's base score. If I gain another rank in the Cult I only have 1 POW left to purchase a gift, or I can increase my available POW by sacrificing CHA through tattooing or dedicating more POW.
Is that right? *edit* Or does each skill you increase require it's own gift, i.e. you take the gift twice for 2 skills at a total cost of 3 points of dedicated POW?
