When Mireu is killed 5x in a row, that entire server can earn a maximum of 100pts per day.
Meaning it will only take 12 days for one of these on servers that have killed Mireu 5 or more times in a row.
So if you want to enter this market, DI requirement is having the char at lv99 for the NPC to give option. Escha Zitah is readily available with almost no RoV missions done. Just park your mule in Escha zitah near Affi, when you see Azi Dahaka warning, log, grab points/keys, do join DI, earn points and log off
