Where to Find the Refinement Tool in Rise of the Tomb Raider
The Refinement Tool can be purchased anytime after you’ve obtained the enhancement tool from the Supply Shack. You’re going to need to use Byzantine Coins for it. 175 to be exact. If that is too steep a price for you, you can always go coin hunting by reading Monoliths. Monoliths will pin point coin caches in an area for you, giving you access to large amount of Byzantine Coins.
The problem is, some monoliths require high amounts of language skill to access them. Make sure you are reading every relic/manuscript/mural that you can find in order to raise your language skills as high as possible.
You might have to come back for this one later on in Rise of the Tomb Raider once your skills are higher and you’re stacking Byzantine Coins to the ceiling.
