My understanding of the item is that I should, by default, have 3 stacks of Void Barrier. But there have been multiple occasions while playing Online I’ve had 4-6 stacks - and no, this isn’t happening because I’ve dropped below my endurance threshold. I’m unsure if the extra stacks are actually doing anything.
Secondly, Void Barrier stacks seems to have a duration and they eventually fall off? And they don’t come back after. I can’t see any mention on the item that these stacks should have a duration. This leads to me needing to re-equip the item to have the stacks start generating again, which I’m really hoping isn’t the intended design of the item.
