Just linking my sheet here so I don't forget where it is.

I'm avoiding Divine Metamagic because I'm trying to keep her at a reasonable level of power - I don't really think a maximised and empowered Tsunami is really fun for anyone - but I am grabbing a few other uses for turn undead like Animal Devotion and Divine Spell Power to give her a bit more flexibility.

I haven't really settled on any specific build yet, though.
