While fighting mud elementals, sometimes a message pops up saying that a mud elemental protects your weapon, whereas mud elementals cause your weapons to rust. That message seems to be wrong. It seems to pop up when you have got a successful reflex save against rusting while attacking the mud elemental. Maybe it should be "you protect your melee weapon", or "the small mud elemental fails to corrode your weapon" or something like that, currently it just doesn't make sense.
