The Modified B-7 is a sidearm, and like every random-roll legendary in Destiny 2 the gun is easy and the roll is not. This page sells both: copies, or a copy with the columns you name.
What you choose
| Option | What it means |
|---|---|
| Roll with random perks | Copies of the weapon. No promise about the columns. |
| Roll with 1 guaranteed perk | One column locked to your pick. |
| God roll — 2 guaranteed perks | Both columns locked. The rung that buys an outcome. |
| Rolls | 1 to 10 copies in one order. |
Which rung to take
Ten random rolls is not a cheaper route to a god roll — it is a more expensive one with no promise at the end. If you know the two perks you want, buy them; if you just want the gun in your vault, buy one roll.
What it has cost
Two confirmed orders, a small sample and worth naming as such: $36 and $99, the difference being guaranteed perks versus a plain farm.
