Tome of Radiance: Mastering the Power of Love and Justice

Concentrating on a spell to maintain it is already a standard action. This is not actually an action tax, just a clarification.

And you misunderstand here, that this effect is not one that requires any form of concentration. That's...kinda the point.

The damage bonus from this ability (as in how far above KD) is already capped at +5, because knowledge devotion is capped at +5. You get the ability at 3rd level. Capping it at class level is not terribly useful, since by 12th level, +2 extra damage/hit is not going to break anything.

And this ability doubles the damage bonus granted as long as your class level is high enough. Considering you can take this class at level 5 (where's it's mean to be taken), that's reasonable in my mind.

Divination, used creatively, can be utterly devestating to an intrigue/mystery plotline.

Say you're looking for an individual whose being hidden by magic from divination. So you use divination to find out where the clothes they're going to wear tomorrow are right now. Or where they're going to pee next. If that doesn't work, you divine who they talk to most often who is not protected from divination spells. The list goes on.

With a limit to uses, there's a hard cap on how many levels of indirection you can use to track someone down in a single day. Without that cap, you can bypass virtually any challenge with a social component.

And the issue there being that all a DM has to do is be willing to hang mystic curtains around their big bad or whatever. Which is remarkably simple to do.

By RAW, yes. By RAI - and if used by any sane DM - no, it won't. And I have added a cap
