Question about 'proc on any basic attack'

[kioro-djirane]

I'm a newb in GD and just want some enlightment about a mechanic. I kind of know the answer but I'm still not 100% sure of it.

When I saw the Nightshade class and all those 'proc on any basic attack' it seemed cool to stack them but after learned the first one I saw it also modified the animation of my basic attack... So now, I'm very doutbful that they will stack. Is my hunch correct ? If yes, how does it actualy work when you stack more than 1 ? Is it even worth it ?

you can stack them untill you have 100% chance when you add them all up

top row of NB skills, belgo shears, quick cuts, whirling death,execution are called WPS; weapon pool skills
they are a special type of proc that only triggers from auto attacks and default attack replacers (which are in turn themselves specific skills)
you can't trigger 2 wps "at the same time", that's not their puporse
they modify and enhance your normal auto attacks and boost them in their own specific way; your auto attack gets turned into belgo shears etc
unlike other procs these also stack additively together, so while they can't happen at the same time, they can pool together and rule out regular normal unmodified auto attacks
so if you get 25% shears, 25% quick cuts, 25% whirling etc etc combined 100% you will never do normal "blank"/unmodified auto attacks and will always ever do wps/modified attacks
^this is contra to other regular procs that dont' stack like that and act independently
