All up for this.
At the moment, the Corvis feels like what could be a good weapon that's had its tendons cut by strange scaling.
Changing it to scale with cel's an option, or having it work with dark instead of wind both work, as have been suggested.
Or even just straight skill to leave it the most open, but that's a tad boring.

Whilst I've figured out a number of builds that could make it work, they have to be pretty specific to be all too viable. Honestly, any of these fixes could make the Corvis a weapon that's used, instead of the niche shadow of what it could be.
