Question about the Cleric, Domains and Devotion feats.

[Count_Jaschk]

I've read somewhere that the cleric may opt to lose her ability to cast domain spells and instead pick up devotion feats.

In which book can I find this rule? o.O

[TaiLiu]

Complete Champion.

[Curmudgeon]

You lose the granted powers as well as the spells, though.
