Yeah I feel Invisibility's a little weird on this server. Back on the old PWs I played on, Invisibility potions were a safety net, ALL smart adventurers would carry one, or five. Get into a fight they can't win, or need to make a hasty retreat, pop an invis and GTFO of there. But here it seems going invisible doesn't really do much to save the asses of those trying to flee when a battle goes wrong.
