Q: What are masterwork rolls?
A: Most legendary weapons are capable of being Masterworked. The masterwork system is a way for you to upgrade your favorite weapons to their maximum potential.
Q: What does it take to upgrade a weapon to a masterwork?
A: Upgrading your weapons, in broad terms, takes a small amount of glimmer, legendary shards, and, most importantly, Enhancement Cores.
Depending on what Tier your weapon is at, the requirements to raise it to the next tier increase the closer the weapon is to being fully masterworked (Tier 10).
Q: What benefits do I get for masterworking a weapon?
A: Each tier that you increase your weapon will grant a small buff to a single stat, chosen randomly when the item drops.
Beyond that, at Tier 5 you gain access to a kill tracker. At Tier 10, your multi-kills will generate orbs of light.
Q: So what are these "masterwork roll" stats?
A: These are the possible stats that upgrading your weapon will grant a bonus to. Depending on what tier you are at, you can grant anywhere from 1-10 additional points in any of the stats listed to your weapon.
Q: Any catch with this?
A: The Bungie API currently says that all weapons can potentially roll with all stats as their masterwork stat. This obviously isn't accurate, as Blast Radius isn't applicable to, say, Auto Rifles.
The list you see on this page is trimmed to only show stats that actually appear on the weapon. However, it is possible that Bungie has additional logic behind the scenes that further filters these
possibilities to, for example, prevent certain items from being able to have an Impact masterwork. Until Bungie modifies the API files to 100% accurately display which masterwork stats are possible on
each item, take what you see here with a pinch of salt.
"We have Forebearance at home."
Forebearance at home:
...No wait, thats a lie, BRAVE Forebearance is Forebearance at home. THIS is Undercurrent but Greenish, an Arc Vanguard Nightfall Adept Wave Frame Grenade Launcher - try saying that five times fast. In terms of perks, really the biggest one is Voltshot in column 4, which allows it to have a niche beyond Forebearance - subclass synergy via Jolt. Other options in this slot boil down to either Attrition Orbs (which requires either 3 or 12 hits, the info tab isn't clear) or your preferred flavour of damage.
For Column 3, you have a fair few options - Ambitious Assassin, Stats for All, Field Prep - but by far the most popular options are Demolitionist (because who doesn't love throwing grenades?) and Lead From Gold (never run out of ammo again!). I'm not too attached to either, so pick one.
Overall, theres an Undercurrent of potential to this thing - Voltshot on a wave frame is cool, especially for Arc or Prismatic subclasses. However, its not quite up to the level of either Forebearance, Disciple of Add Clear, or Forebearance, Explosion Lieutenant of the BRAVE Familia. Choose your faction wisely, young blueberry... and don't be fussed about it being an Adept or not. Forebearance the Elder is craftable AND has its own Adept, Forebearance the Younger is enhanceable. In the end, an Adept mod isn't going to do much to change where it stands on the leaderboard.
...Oh right PvP. Well, it has sweet eff all for PvP perks, so don't bother. No, not even to show off your shiny Adept weapon.
