[Lost Ark]1621Night's Edge Soul Eater - Ivory Tower Hard G1-4 

Kind of jumping back in casually with Lost Ark. I have a SE NE sitting at 1580 with 7/8 event gems. Should I stay with hallu set 413/422 60/40 stat or go for nm 413 full crit? I hear that 413 full crit is clunky without high level cd gems. Also any class recommendation for returning player? i kind of forgot how to play the game to be honest lol.

I have Lv9 gems and use Nightmare Set. Is it better to have Master or Crit in the Elixir?

I use the same gems as you, what would you improve step by step. thank you very much for the content
