Black knight kill enhancer

The Black knight kill enhancer is a possible item received from the Motherlode Maw's daily random reward if you have at least level 95 in all skills. You also have a chance of getting it by trading Wythien ten crystal motherlode shards, or you can talk to Wythien to convert an unfocused reward enhancer to a Black knight kill enhancer, but it will only have 15 charges instead of 30.

When the enhancer is in your inventory, every Black Knight you kill will be worth twice as many kills in the White Knight Rankings. The enhancer begins with 30 charges and one charge is used whenever you kill a Black Knight. It is unknown how this affects killing Elite Black Knights or White Knights. It will disappear when all the charges have been used up.
