Uh... I hate to be a bother, but I got the glowshrooms and still can't enter any caves or anything, it says I need a source of light. Is there a crafting recipe I can use to make them work? Even with the update this issue persists
You can build workshop at home now and make a torch there. It can be used that way.
If it comes to glowshrooms - you need five of them. If you have five in your inventory you can obtain an amulet from the witch or from the priestess (Only from one of them).
And like kentaureus said, you need to have a proper item equipped.
