So, at the top of it, 2 br's and the lure eb takes about 1 hour and 5mins. So we could easily do 20 lure ebs a day, so about 100 Psion a day. We've got 20 odd days to do this event so we could get 2000 Psion by the time the event ends.
That said it'd be more reasonable to assume a normal person can hit 8-12 of em per day. So still about 40-60 Psion a day.
