How do different damage buff stack?

[Vec0]

I'm playing gunlancer and I'm having access to more and more source of damage buffs (combat readiness engraving+barricade+what not) but I still have NO IDEA what they actualy increase nor how do they interact between each others. Does my barricade extra dmg get increase by lets say Grudge, do they stack multiplicatively ? etc.

With so many sources of damage thanks to engravings:
- Stabilized Status
- Hit Master
- Grudge
- Cursed Doll
- Adrenaline

How do I know which combination is the best for me? I'm ilvl 1020 and I have no idea if i should focuse on engravings that boost "damage" (like barricade, grudge etc) or attack power (Cursed doll) etc.

Also spells' damage for gunlancer are influenced by your specialization so that's yet another factor in the dmg calculation fomrula

If I'm correct its like (Attack power + %attack.power) * Dmg increase
There was some kind of formula like this, might be a bit wrong. Saw that in a video, I dont remember what the video was but I guess it was about engravings.

%attack.power is like if your attack power is 500, and %50 atk.pwr means 250 like that.(example)

There's alot of calculated stuff. May be different between KR+RU and AGS+JP regions.
