Holy
3 lillies - holy becomes instant cast and its potency increased by additional 50
(holy can easily be used more often)

Divine benison
3 lillies - increase healing by 15% when target affected by divine benison.
(Instead of applying db on tank during prepull, this function allows white mage to place 3 lillies db on tank who is at the verge of dying to top them up quickly.

Plenary indulgence
For the love of god, remove confession and replace them with lillies. Easy fix.
