Why do Destiny 2 stats work in tiers?

Each stat runs from 0 to 100 but the in-game benefit, such as ability cooldown or survivability, is granted per completed tier of 10 points. Points sitting inside an unfinished tier do nothing until the tier is full, so rounding stats to a multiple of ten is the efficient play.

How does the optimizer decide where points go?

It uses a greedy allocator: it repeatedly gives a full tier of ten points to the highest-weight stat that is still under the 100 cap. This maximizes total weighted tiers because the benefit accrues per tier, not per individual point.

What does the wasted points figure mean?

Wasted points are leftover points that landed inside a partial tier and therefore grant no bonus. If you see wasted points, lowering a stat to its nearest multiple of ten and moving those points elsewhere usually gains you a tier.

Does this use exact in-game armor roll values?

No. It is a planning model that shows the best way to allocate a pool of points across tier breakpoints. Real armor pieces roll fixed stat spreads, so use this to set targets, then chase armor and mods that hit those tiers.

Can two stats share the same weight?

Yes. When weights tie, the optimizer fills the stat with the lower current value first, spreading tiers evenly between the tied stats. Set unique weights if you want a strict order.

The Destiny 2 Stat Optimizer turns a raw pool of stat points into the most efficient spread across your build. Because Destiny 2 rewards completed tiers rather than individual points, the smart move is always to land on multiples of ten — and this tool does exactly that, in priority order.

How it works

Each of the six stats runs from 0 to 100 and is read in tiers of ten. The benefit you actually feel — faster ability regen, more survivability — arrives at each tier breakpoint. A stat of 79 gives the same in-game tier (7) as a stat of 70, so the nine extra points are wasted.

The optimizer fills tiers greedily by weight:

while points >= 10 and a stat under its 100 cap exists:
  pick the highest-weight eligible stat
  add one full tier (10 points)

Any sub-tier remainder is then placed on the highest-weight stat that can still take it, and flagged as a partial — those points grant no tier until topped up.

Tips and example

Suppose you have 300 points and weight Resilience 8, Recovery 7, and Discipline 5. The optimizer pushes Resilience and Recovery toward 100 (tier 10) before touching lower-priority stats, returning a clean spread with zero wasted points. If you instead spread points evenly you might land on values like 53 or 67 and silently lose several tiers.

Use the result as a target, then build toward it with armor mods, fragments, and well-rolled pieces. The copy button exports your plan so you can paste it into a fireteam chat or a build note.
