I think the default setting is 33%, but if you are at a computer with WE just go to Object Editor -> Abilities -> In the field with all the abilities, press Ctrl + F and type banish and see for your self
I don't think I'm dealing with quite the same pressures though, at the very least its a significantly smaller system. For the time being I'm just going to put together a quick scrubby box though and hope it works good enough to not make my house toxic
I do know this - xenforo dropped the ball by not keeping the vbulletin reputation comments as a feature.
