Miser with Magic feat question

[Elder-Basilisk]

Come on basilisk... I just read the description and (see below) roleplaying requirements of the Channeling in the book and applied it

Yeah and you can see why the churches would keep it a secret too. I mean, if I were running the Knight of the Gods' church, I'd keep the fact that he grants his clerics such pathetic abilities a secret too. And if I were running the church of the Riftmaster or whichever one it is that gives the energy drain ability, I'd keep that a secret too. Otherwise, you're always the first target in any conflict no matter what--the ability is more dangerous than almost anything any other class can do.

But balanced by roleplaying requirements?

I guess I was thinking more of "special" requirements than "role-playing" requirements. A Sacred Exorcist must be approved by his church for instance. If you think it's unbalanced for wizards to be sacred exorcists, you can make the church disapprove of arcane magic. Etc.

I suppose that it's no harder to do that than to keep a lid on feats as a DM. My impression of the Kalamar book, however, was that it has very little in the way of useful mechanics--most of them either seemed to be dramatically overpowered (Miser with Magic, some channeling abilities, Iron Skin, etc), dramatically underpowered (other channeling abilities) or redundant (Basiran dancer, Brigand, etc core classes).
