I am also working on getting better artifacts and accessories. after you defeat faction war boss level 1, you will get good glyphs. and after spider lvl 13 you will get good accessories. I am working on dragon and spider.
So, today i opened some ancients i had saved and ended up getting my first legendary (Rotos)! i also got tayrel and zargala and vergis wich i ve heard are really usefull, any tips for build and usages for those guys? Maybe any of those can help me progress in spider or dragon?
