In order to understand the rules that govern armor stat rolls we must first understand the concept of
stat groups
. The six armor stats in Destiny 2 are grouped in two buckets of three stats each:
- Mobility, Resilience and Recovery
- Discipline, Intellect and Strength
We will refer to these stat groups as
Stat Group 1
and
Stat Group 2
moving forward.
Given these
stat groups
, the rules that govern legendary armor stat rolls are as follows:
- No single base stat value may be less than 2
- No single base stat value may equal 3, 4 or 5
- No single base stat value may be greater than 30
The sum of the base stat values in each
stat group
may be no less than 22 and no greater than 34
While wearing an
armorer ghost mod
, armor pieces with random stats you acquire will have a guaranteed minimum of 10 in the stat that corresponds to the equipped armorer ghost mod
To put that in plain English: any single stat can roll with any value between 2 and 30 except for 3, 4 or 5. The maximum total base stat value for any legendary armor piece is 68, where 34 stat points come from
Stat Group 1
and 34 stat points come from
Stat Group 2
. The minimum total base stat value for any legendary armor piece is 44, where 22 stat points come from
Stat Group 1
and 22 stat points come from
Stat Group 2
.
Additionally,
armorer ghost mods
(e.g.
Discipline Armorer) can be used to force a minimum of 10 for any single stat of your choosing.
There are a few more rules that govern exactly how stat values are distributed. These rules involve triplets of numbers called
Stat Plugs
. This document will not go into detail about
Stat Plug
rules, but you can read more about such rules in
this Reddit post and explore

this website if you are curious. For the vast majority of people, the five rules listed above are all that matter.
