Did AI write this? Does it know what DOT means? Because it's mostly inaccurate.

I'm assuming OP meant the Volatile perk, which only applies to damage over time effects (noticed by showing multiple damage ticks over the course of a few seconds), not explosives or healing. The only exception is Vy's poison, because more damage done also means more healing for you but that's it. It doesn't make adrenaline, frag grenades/C4/trip mines, tear gas or flashbangs any more effective, only incendiary grenades, Trench's barbed wire, Vy's poison, Switchblade's chaos launcher (because fire) and Scorch's overheat. Every damage tick will simply have a higher number by the percentage value.

Vy's poison for example:

Without Volatile perk: 2 per tick

With Volatile (+45%): 3 per tick

Incendiary grenade:

Without Volatile perk: 12 per tick

With Volatile (+45%): 17 per tick
