My recommendation is to do 4hrs days. 3 Days should be enough to get full void. I usually run it for the full 4 hours or 3hours - break and 1 hour. I generally go with "Attack mode" Everything but Shifters, Prioritize Spinners & Turn on Door feature (If you don't, makes it look hella bot like). Haven't been banned so far and have done it on 3 accounts Full Void + Mage/Range helm.
Definitely agree on the Portal mode - Active mode and Defend Knight mode is by far the best.
@Czar Able to fix the door issue? Majority of the time doesn't open the doors and just spam clicks monsters outside,
