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.
Yes, it's a utility perk that only works with a team, but no matter which playlist you play in either solo or team-wise, you're surrounded by other guardians that are counted as teammates.
Even in PvP like Control can benefit from the boost in reload and handling. Sometimes you and your bro-op work together to take a guardian or two down.
And raids definitely gain benefit with this.
However, only two perks immediately come to mind when paired with Ensemble to it's full benefit: Runneth Over (Kings fall origin trait) and Firing Line (weapon perk)
Runneth Over overflows the magazine based on the number of allies within 15 meters on the completion of your reload animation (almost half of the magazine), while Firing Line gives a 20% boost to damage while in the same 15 meters with at least two guardians (GMs, Strikes, Raids, 3v3 PvP).
It's not the most popular with everyone, but I promise you that if you like working together with teammates or like passive weapon stat boosts, I would recommend this gun.
Taipan FR4, Quillum's Terminus, Smite of Merain, etc.
Of all the perks season 15 had, I'm happy this was one of them. :D
