discern gets you:

You carefully study Kackrik and discern their magical protection.

Kackrik is affected by spellbane.
Kackrik is affected by truesight.
Kackrik is affected by truesight.
Kackrik is affected by resistance.

Should be his rather than their. Also, it seems kind of strange that these are all considered magical protections, being battlerager powers.

Pronoun fixed. That's unfortunately common, and it drives me nuts also.

It is by design that it detects "Power" affects. The description is odd, but it's inconvenient to change unless you can think of a word for both.

Why have a word at all? Just say:

You carefully study Bob and discern his protections.

You'll cover everything that way, and they already know it doesn't tell them communes.

Well, it detects things that aren't really "protections", but I worked something out. FNCR.
