Hey guys im only here to advise you if your trying the hard raid for the first time. you need to have a couple things done on your character. Because the hard raid is nothing like the normal. You dont respond until the next check point. and your buddys cant pick you up.

I advise having a level 29s+ in your game with atleast 1380+ Defence.
And for your weapons Have some sort of arc,void, solar burn damage along with them being 300s. because if they are anything below 280 the enemies are very difficult to kill and same with the oracles. You guys can do as you please but i just thought you should know that these are some tidbits. hope this helps!
