Osmosis combos with the new volatile rounds ability, letting you proc it on your kinetic weapon which would otherwise not be possible. You could run an osmosis primary with a void special and heavy weapon for a full void loadout to take full advantage of volatile rounds and void 3.0 builds in general. It can also combo with things like nezarecs sin of thats your cup of tea. Bonus points if your lucky enough to get a weapon with both osmosis and demolitionist (or adrenaline junkie). I got super lucky with RNG and got a fortissimo slug shotgun with osmosis and demolitionist that is crazy fun to use with void 3.0 builds

So I've been sitting on a goldmine this whole time and never realized it lol. I have a osmosis/demo judgement and I've never fired a shot with it because I was always told judgement isn't all that great, but I might have to give a go

Yeah I'm a little jealous of that one! With the right build that thing will feel like an exotic

Yeah, I gave a go with my null composure and it's very good lol. I could probably do better than null composure in my energy slot so I'll have to play around with other things, but thanks for the tip on that

I think there are only like 3 weapons that can get osmosis demolitionist. New vanguard shotgun The last breath auto rifle Judgement hand cannon And breachlight used to be able to, but well, it's sunset.
