To Masterwork a weapon after the Forsaken update, you need to progress it's masterworked stat through 10 ranks, with different and presumably increasing prices for each level.
I know the first level costs, glimmer, the second glimmer and legendary shards, with the third costing a masterwork core.
What are all ten levels of masterwork progression? Are the materials needed for each level the same for each weapon? I would like to know how many masterwork cores it takes to complete all ten levels.
Best Answer
To fully masterwork a legendary item it will cost you: 10,000 Glimmer, 27 Legendary shards, and 17 Masterwork Cores
There is a thread on reddit, from months ago when masterwork was last changed, and that user fully broke it down here.
Note that these values could change whenever bungie wishes to adjust or rebalance the game.
