Here I was thinking that 4 serums were used to run threat 5 twice and threat 4 twice. Entered threat 4 then realized I screwed up, it consumed the serum but I did no fights and got no mysterium. Only to figure out we only got the exact # and no extra serum this week. So not only did I miss 6k mysterium but 2k titan shards bc I thought it would surely be the 2nd step quest we would need to run 4 times….that HAS 4 paths
