The upside is:
All BOKs (1-5) have been edited and now contain Summoner and DarkLord exc items. They've also been set to drop a wider variety of items than they were droping before in Season2.
Downside:
20% of the droped BOKs will drop Zen. Why? To make things more interesting and to get exc drops depending on your luck
Thx again to Unreal, for helping me editing BOKs.
~Enjoy!
