Finding the best gear in can be a bit of a challenge. While it's possible to buy gear and upgrade it in the Room of Requirement, the quality of the gear is really what makes the biggest difference as to how powerful the final item can become. The most common way that gear is found is through opening the chests that are scattered all throughout the various hidden locations in the game.
There are a few different types of chests though, Eyeball Chests, Collectibles Chests, Big Chests, and Small Chests and the loot that is obtained from the majority of them is random. However, with the use of one common feature getting the best gear possible is very easy.

A common feature of video games that has been a staple for a very long time is the ability to save games. By making a manual save file before opening a chest players can open the chest and if the item is not an upgrade they can load the previous save file before opening the chest and open it again for a chance to receive a better piece of gear.
