I've done my ER for my mythical weapon. So my question is...Is there a way to go back and do the quest itself for the achievement? According to every wiki I've looked at yes. But when I go to try to talk to the quest giver he has nothing to say to me and no quest. So am I going to be unable to get the Mythical Brandisher Achievement? Thanks in advance
From what I understand, you can only do the mythical quest if you have NOT done your repercussions. The repercussions are to make your mythical abilities into spells instead of being required to use a weapon you will out level to use them. Wouldn't make sense to have those abilities already while on a quest to get them, would it?
If you do your Repercussion then finish your Mythical you will not get your name sent across the server. I know this because I did my quest for Enervated Vel'Arek before I did the Slayer Quest for the Mythical. Sadly I was only missing Overking Selrach Di'Zok too.
