Pocket Mirror

Stoned locks you in place as a statue. You cannot move, swing anything or drink a potion, but gravity still applies, so what kills you is where you were standing when it landed. Over a lava pool or a long drop it is a death sentence.

Medusa is the only thing in the world that applies it, and she does it at range the moment she has line of sight on you. That is why marble caves punish careless movement: you round a corner, the cast starts, and you are frozen before you can back off. With this equipped you can walk up and hit her like any other enemy.

Only Medusas that spawn on their own count, so a statue farm will never hand you one. You have to find real marble caves and clear them the slow way.

It also shimmers into a Blindfold and back, so a single drop covers both immunity accessories depending on what you are heading into, and it feeds the Reflective Shades later if you are building toward a combined immunity slot.
