I can confirm that some Orcs can see invisible. Had one charge our group as
we where going to purchase more animated sword spells and we verified
everyone's outdoor camo was still up as the critter charged. The question I
have is this: Is the Orc seeing invisible due to a spell cast by an Orc or
by other means (npc's, players, etc.). Just curious as to the origin, as
I've never seen the source of this irritation. Strongly recommend you do not
make the trip alone.
