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.
Tested in S22 against a Void-shielded enemy Minotaur at Zydron's gate on the Moon, and also another in a Neomuna patrol zone, just in case there was some location weirdness. Also tested what happens when combined with Under-Over, and the two effects just additive (not multiplicative) meaning that both bonuses capped out at doing 2x perk-less damage.
They instead created "deconstruction" *SMH
Bungie is too busy nerfing exotics to make already not working existing things, work properly.
That said, its not a useless perk, it is a useful perk if it is in the 3rd column, which usual features utility perks, and not the 4th column, which usually has more dmg perks.
Moreover if its also on a weapon archetype that has the higher RoF and capacity vs lower base dmg.
And of course, if said weapon type is featured for Anti-barrier during that season
Currently good candidates would be Trace rifles, frontier's cry, Ogma Pr6, Plug One.1, and maybe Doom of Chelchis
This perk isnt useful enough to be considered a normal dmg perk option.
It's just community recommendations from hundreds of people testing perks. If you don't like a perk, it's no one's fault.
TBH, the perk is actually great on Machine Guns and Trace Rifles, but I've had bad luck with Pulse and Scout (even though the scouts with it are actually good).
It's all personal preference, but don't dis the community for a gathered consensus.
