Debuffs from Swap Ammo
I think that the debuffs last a certain amount of time, during that time I think another debuff like it will stack.
He will honor his words; he will definitely carry out his actions. What he promises he will fulfill. He does not care about his bodily self, putting his life and death aside to come forward for another's troubled besiegement. He does not boast about his ability, or shamelessly extol his own virtues. - Sima Qian.
The Dual Pistols debuffs are applied on a per-attack basis. Every attack has the Standard, Incendiary, Cryo and Chemical attributes; it's just that certain ones are used depending on which Swap Ammo toggle you have running.
The debuffs are -Speed -Recharge from Cryo Rounds, and -Damage from Chemical Rounds. If you use, say, Dual Wield to apply a debuff, then use it again before the debuff wears off, you have an opportunity for stacking. The Cryo debuffs will stack from the same power, but the Chemical debuff will not. Having said that, if you use Chemical for Empty Clips and Dual Wield together, their debuffs will stack with each other.
EDIT:
Pistols is unique in that its only secondary effect is -Defense while in Standard mode (which will stack with itself). If used with any Swap Ammo toggle, it will only deal damage.
Do the different debuffs from Swap Ammo stack?
Thanks
