Item description:

2/3 Winchester's game won, 4/5 bullet encounters.

Those 2 encounters are rng so you will have to look for them on your own on gungeon runs. I recommend trying to get any
item that makes you fly for making Winchester's game super easy. That minigame doesn't spawn that often and it's pretty easy
to miss a bullet making you fail and have to search the encounter again on another run.

Important note about using elevator shortcuts. Once you use the shortcut to find the npc just do one run and DON'T use quick
retry. Go back to the lobby and use the elevator again to reset totally the level. You won't find any if you quick retry,
trust me ^^'

A bit after after this save i got the Rider trophy killing around 10 more enemies mounted on a minecart on floor 3.
