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.
All serious now, Relentless Strikes and One For All is a pretty great combo if you ask me, definitely worth using.
Anyway, much like Eternitys Edge, this has only 4 perks and they aren't the best out there. One for All is your best damage perk option, with the other perks depending on what you're doing. Assassins Blade is fun on this weapon, though not the strongest perk. In PvP, while it looks cool it doesn't hang with the Meta(TM) picks, given range and Eager Edge is king over there.
Overall, a decent enough sword, but nowhere near the best. Word to the wise, go work up a Goldtusk pattern instead - much better rolls on the same frame, and Craftable to boot. If Lightfalls year is over, doubtless they'll add it to an Exotic mission loot pool like with other Seasonal weapons. Oh also this is a world drop most likely, so that doesn't help either.
