Why not [Internal Bleeding]? Impact status effect are mandatory, and the [Nagantaka]'s rate of fire is exactly 2.5, so it's a 70% slash prob.

I know, but we are spending a mod slot and 15 drain just to get 70% slash proc prob. We alredy have a 90% slash dmg weapon with more than 100% status effect. So nearly each hit will proc slash. Sometime that hit will proc 2 slash. Instead of that, I rather using Galvaniced Aptitude in order to get the status bonus I need AND at least 80% extra dmg (160% at 2 kills), 40% comes from slash proc and 40% from that mandatory impact. And we are saving 3 drain points! Those 3 points make us save one Forma.

Due to the fact that in slash damage equation, elemental bonus are ignored, u can add some more crit/bleed mods instead in order to get better slas dmg, but viral status is too powerful to ignore it. So if u have a convenient strategy to apply viral (vulpaphila) u can go on with that.
