I bought a bunch of invisibility potions at another player's shop but if I try and use one, a message pops up saying that it's not allowed. Are these potions completely useless on SB? I was going to sell them in my shop, but don't want to put them out if they won't be able to be used by people who buy them.
Yeah, invisibility potions do not work in Skyblock. Since the potion can be abused such as players hiding their username when scamming someone or trolling someone.
Eh.. I flew to an island and found a shop. Don't even remember whose it was. It's fine... just didn't want to sell them in my shop if they wouldn't work. I'll just use them to put in item frames for other potions there. :)
