Oi! Who's being mean to my elephants?

While accompanying my priestesses on ward rounds recently, I discovered to my dismay that well over 50% of our elephants had had both eyes poked out. Naturally we were all distressed about this - Elephants are, after all, our friends.

Are some battle aflictions more common than others, or is there some sneaky magical trick I should be looking out for?

I can see a priestess with a gleam in her eye and a nasty looking sacrificial dagger in her hand. She wants to know the answer, and I think there could be trouble when we find the culprit...
