4 of these are a choice you make once. Builds of the Onos show which ones they took. Evolutions are printed, never counted: most are conditional — on a weakpoint hit, with an ability up, for a few seconds — and the engine has no model for a trigger, a chance or a duration.

(Riven disposition)

2 — a stronger disposition means larger riven rolls, and it moves when the community changes how much it uses this weapon.
