Arachne

I've seen Arachne use a skill similar to Ice_Hold where glowing threads shoot out from its hands and petrify the player. I saw the petrification symbol thingy and the person died shortly afterwards. It doesn't have any skill that might do that on the monster's page. If I had a screenshot i'd upload it but we were busy killing it before the person died, which he did anyway. I don't know why I posted this here but ya I dunno.
