A spiky surprise

Exploration Stage: Borderland
From: Ollie Articus
Description: How do you know you're cursed, you ask? Because, you know, there were clear signs. Today I received a gift in a sharp box from a sender whose name is concealed. It should be nearby, so look for it.
Completed: That's the gift I was talking about. I think the curse owner sent it to me. See these sharp corners? Negative energy manifests itself in this way. I haven't opened the gift because it could be dangerous.
