Osmosis basically turns a kinetic weapon into an energy weapon when it activates, right? I had a build that I wanted to try with Verity's Brow and a Breachlight that has Demolitionist and Osmosis on it. I was curious if I could run around with a solar Breachlight and slay a bunch of enemies to trigger Death Throes. To my disappointment, it did not. I mean technically Breachlight is still a kinetic weapon by design, so maybe it's fine as it is. But if Osmosis worked with Verity's Brow, I feel like that could make sense too and I'd really enjoy running that along with an energy special weapon. It sounds insane but it would be very fun.
