This is bad logic, lets make ash staff trails that requires you kill 1000 mobs per trail then end up with a D40 staff in the end.
this thead is to tell SE issues on the game.
1. why make a path that ends up with a "suck" weapon?
2. why is said path of bad weapon one of the longest, or is the longest paths of said bad weapon?
if you are going to make "crap" weapons, it is a waiste of programing to make them. it is likey SE missed these issues because it just does not make sence to have it ( waste of space/ time/ what not)
