After using a single Sigil of Corruption for most of my leveling i decided to stack diffrent sigils at the same time.
What actually happens is every kill whichever sigil goes off first in my case Corruption only that will stack to 25 leaveing the rest of your sigils useless. I tried to stack to 25 to see if after a full stack would the other sigils pop into action but i found out they didnt.
for example in my primary weapons slots i use a Sword and torch with the sword having the Perception sigil while the torch has the corruption one. Per kill i expected to get a single stack of Perception and Corruption increaseing my condition and precision +7.
I also have added the Blood sigil with my secondary weapon set a mainhand axe with a dagger. if i decided to equip the sigil that adds +7 healing i would expect the same behavior above.
If these are not meant to stack at all i would appreciate a response saying so.
Thank you for the game :)
