I want to propose adding an additional drop for Orfen and for Zaken, AQ and Core (when they will be). For example, 1 Blessed enchant armor S and with a small probability Blessed enchant weapon S.
Still, Orfen and other future bosses are also more likely to be more difficult than Anakim / Lilith. Therefore, I believe that they should give some pleasant bonus, otherwise interest will be lost.
Yes, and slightly increase the amount of drop from Antharas, otherwise it takes longer to kill him than other RBs, and the drop from him is about the same as from others (except for jewelry and bless enchants).
