If I shot an invisible creature with an arrow (perhaps by pinpointing it after it cast a spell) would the arrow disappear, or would it visibly stick to the creature and allow one to pinpoint it with greater ease?
For reference, I'm playing the Rise of the Runelords AP and we encountered a small demon in some catacombs who was invisible. She cast a spell at us and my ally successfully pinpointed her and hit her with an arrow. We're doing a play by post so that's where we've left off, but the GM is at a loss as to what to do.
Thanks in advance!
