i tried searching for this here and other sites but was unsuccessful. would like to know if the GSAP (Greater Swift Attack Potion) stacks up with the Haste SA on a dual sword?
Any wearpon SA's stack with any buffs, skills and armor bonuces. So if you got kesh*kesh, some attack speed passive, talum heavy and buff for attack speed (hastle, gsap, chant of rage) it all affect's your's attack speed.
Buff with identical effects and potions dont stack. For example acumen, (greater) magic hastle potion, chant of fire and wisdom of paagrio (?) they will replace each other.
