Where the epic raid boss Zaken stands, how to get inside his ship, what the monsters around him are like and what drops from him besides the earring.
The epic raid boss Zaken is in the location Devil's Isle, in its farthest part, on an abandoned ship. The way to Zaken is set out in detail in the description of the location, so you will definitely not get lost. Here we will talk about the raid boss himself and about the ways of getting in to him. Free servers, as always, excel in variety: somewhere you enter to Zaken through a raised grating, somewhere through an NPC next to the grating, and somewhere they even put a separate NPC on the deck among the mobs, and he ports you inside. The classical way is clearer to me, when we stand and wait until 00:00 game time for the grating to open.
Zaken has no minions, but everything is packed with mobs, and they only look like ordinary ones: in fact all their characteristics are raised, from HP to attack and defence. And there is no drop from them at all except ordinary healing potions.
In Zaken's drop there are only top C-grade weapons and low B-grade weapons and armor. And the earring, naturally. The drop of 
Zaken's Earring is 100%.
