what wrong with spoil?

hey, can u tell me what wrong with spoil berserker blade edge?
i farming big groups "oel mahum shamans" with my wl and mage 2-3 hours and have noone berserker blade edge
chanse in your wiki 0.49% without PA, and 0.59% with pa. Every group was 10-15 shamans, i farming 4 group in 20 mins and noone berserker blade edge.

There is a problem with spoil in Ant Nest too, Ant Noble Captain spoil with PA 100% Thread 1-5, but in fact sometimes mobs are blank (spoil was activated)

I ask another guy, he farm 5 hour and get only 1 berserker blade edge. In EV mages can drop 2-3 pieces to top c mage weapon, it is wrong, please up chanse to spoil pieces of berserker

Nice server, nice admins
