Everyone's going to tell you to just look up Ejiin on Ragnarok until he quits, and if you want progressive sets to work towards well gl on figuring that one out on your own, the community only cares about the best gear you can possibly wear and doesn't take into account new people.
If you have a relic and and mythic and somehow cannot figure out how to gear up properly on your own...you are doing something terribly wrong. It's unhelpful comments like this that make the people trying to keep up the guide heading for the hills.
Should look into Foxfire's guide on BG (you know, the "mediocre" one). It is a good source for where to start and where to finish. Everything in between is
based on your gear. So some choices will have to be made by you.
