WPS Activation and Normal-Attack Allocation

Weapon Pool Skills (WPS) do not all fire together. One selection is made from their weights and the normal-attack remainder.

Standard explanation

When total WPS weight is at or below 100%, each WPS retains its listed chance and the remainder is a normal attack. Above 100%, no normal-attack slot remains and the WPS candidates share selection according to their weights.

Deep explanation

Below-100 effective weights retain their declared cumulative weight while their sum is at most 100.
When their sum exceeds 100, normal attacks are not selected and the WPS candidates are selected from the accumulated weight.
At-least-100 candidates use a separate cumulative draw and occupy the remaining normal-attack slot.
The engine’s inclusive integer draw gives the first candidate one additional integer bucket, so exact engine probability can differ slightly from displayed percentage.

Effective WPS weight = trunc(sum flat weights × (1 + sum weight modifiers / 100))
Normal-attack remainder = max(0, 100 - total effective below-100 weight)
Approximate share above 100% = individual WPS weight / total WPS weight

Calculated results

Case	Calculation	Result
Total below 100%	`WPS A=30%, WPS B=25%: 100 - 30 - 25`	A 30%, B 25%, normal attack 45%
Total above 100%	`WPS A=80%, WPS B=60%: A = 80 / 140, B = 60 / 140`	A about 57.14%, B about 42.86%, normal attack 0%
Weight modifier	`flat weight=40%, weight modifier=25%: trunc(40 × 1.25)`	effective weight 50%

Published game data is 1.3.0.6. The binary evidence for the selection logic was inspected in 1.3.0.4 and has not been re-audited against the 1.3.0.6 binary. Do not conflate displayed percentages with exact engine integer-bucket probabilities.

Summary

Key point: At 100% WPS, normal attacks no longer occur. Above 100%, the number of activations does not increase; the WPS candidates compete for shares in proportion to their weights.
