SSF Ruthless Vaal Orb (I find a way!)

Guys I have posted feedback on my SSFR experience, and the worst of it is lack of vaal orb and regret orbs. I am no 90/115 on atlas now. Farming vaal orb is possible. When we killed a boss in a corrupted map, it has a good chance to drop a vaal orb like 30-50%. We can farm kirac mission that is corrupted to farm that vaal orb. Although it sounds a little, but its already maybe triple the drop rate of vaal orb now.

Forgot to mention, if you farmed a corrupted map with multiple bosses, all bosses has the chance to drop vaal orb!
