I too require help with this (and presumably the two other EDs proceeding this one). I've managed to get to the dragon boss, and I've literally wasted a whole day trying to solo it on story mode, researching and trying different strategies and weapon types with a realistic budget to no avail.
Why lock the quest cape behind such unfair requirements (requirements which aren't even specified in the actual quest guide I might add). To me, these particular requirements need you to be fully equipped with super expensive end-game gear, and also operates on the assumption that fellow standard quest players such as myself are adept at bossing and all that entails (frantic switching, Soul Split, access to high DPS special equipment etc).
Rant over. If anyone else is currently stuck in the same boat, feel free to add me!
