For the Nexus, or out of all I got
?
Nexus was something like 170 pearls, so a simple 50-60 pearl dispel would've taken it down - though I kept around 300 pearls at all times for next nexus in case it was dispelled. Out of those pearls I got, I used mostly all of them to various things - mainly wishing. I had 30-40 clams going on at peak also I think.
