Info about "Rolls with Guaranteed Perk":

• If you choose two or More Guaranteed Perks in "Rolls with Guaranteed Perk List" Difficulty then we will obtain them on different weapons, not just one of them. 
• If you need two Guaranteed Perks for a single weapon, you need to choose the "God Rolls List" Difficulty and Choose a Roll there.
• If you didn't find the God Roll that you need or you want a unique Roll then you should contact our Support Team.

If your Light Level is not high enough, then you can buy Destiny 2 Power Level boost which will grant you access to new content and will also help your character reach maximum light level a lot quicker.
