The Relic Weapon effect(the orange one) that gives you hits 15% chance to knockback and slow don't work for any weapon i found to have that enchantment.
I really hope that devs can fix this asap because this would be one of my build defining enchantments for my Heavy Bolter
Yes of course i take that into account.
I already thought that it might have a internal cd and "proc" while the mob is in green and then when he gets to yellow/red it cant proc anymore for some seconds but even on mobs that live like 10-20 sec it wont proc a single time
And 15% chance is pretty much so this not that rng (especially with the super high RPM from the heavy bolter)
I also tested some other relic effects on the Heavy Bolter none of them seem to work.
As long as the sup bar is still green, that makes enemies completely immune to slow, stun, knockback, etc.
