How does the optimizer distribute points?

It divides your total points among the stats in proportion to their weights. A stat with weight 6 out of a total weight of 12 receives half the points. The split is the weight divided by the sum of all weights, multiplied by available points.

How are fractional points handled?

Stat points are whole numbers, so each share is floored first. The remaining points, equal to your total minus the sum of the floors, are handed out one at a time to the stats with the largest fractional remainders, which is the standard largest-remainder rounding method.

What if I give every stat the same weight?

Equal weights split your points as evenly as possible, with any remainder going to the first stats. This is a balanced build that does not specialise, useful for flexible or hybrid playstyles.

Should one stat ever get a weight of zero?

Yes. A weight of zero means that stat receives no points, which is correct for builds that ignore a stat entirely, such as a pure caster putting nothing into a melee attribute. The other stats absorb its share.

Is proportional weighting really optimal?

It is optimal when each stat's benefit is roughly linear and independent, which holds for many builds. If a stat has hard breakpoints or diminishing returns, treat the result as a strong starting point and nudge points toward the next breakpoint.

Distributing stat points by feel usually leaves a build slightly off, and the arithmetic of splitting whole points by priority is fiddly. This optimizer turns your playstyle weights into an exact, whole-number allocation that always sums to your available points.

How it works

Each stat’s share is proportional to its weight, then whole-number rounding fixes the totals:

share(s)  = points × weight(s) / Σ weights
floor each share, then distribute leftover = points − Σ floors
leftovers go to the stats with the largest fractional remainders

This is the largest-remainder method, the same technique used to apportion seats by vote share, and it guarantees the assigned points add up exactly to what you have.

Example and tips

With 100 points and weights of Strength 6, Agility 3, Intelligence 1, the totals are 60, 30, and 10. If the proportions produce fractions, the leftover points go to whichever stats were closest to rounding up. Set a stat’s weight to zero to exclude it entirely, and treat the result as a baseline — if your build has a known breakpoint, shift a few points to land exactly on it.
