An Incarnon Genesis adapter, earned in Duviri's Circuit, gives the Mk1-Bo a second form. Evolution I comes with the adapter; each one after it is unlocked by its own challenge, and offers a choice that cannot be undone without a new adapter.

3 of these are a choice you make once. Builds of the Mk1-Bo 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)

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