I dont know if all specs have dirty blast.
But as far as I understand: mm uses charged burst,
sabo the thermal Grenade
and dirty fighter the dirty blast skill in their Rotation.
Edit: THX @ whojoo for the link.
Sadly I am a bit more confused now. Since I learned there are basic accuracy, special and tech.
I'm not at the Computer for some days but I believe the tooltipps doesn't explain what type it is.
Could you give me examples for those types, maybe by the dass oft a Sabo gunslinger?
I also read that kinetic and energy damage are reduced through the armor - like you wrote.
Does that mean all others do not be affected? Internal, elemental and whatever else is available?
