The raid boss Julietta if anything is extremely buggy in phase 1 her little push that throws up debris has a chance to just dc you instantly. Other than that id reccomend taking off your gear if ur trying to do the achievements so that you can actually farm the jellys in the final stage without accidentally killing her. Drops boxes that give randomn ranmaru/pensalir/emp gear that is +5/+7/+9 70% spell traced and is epic but does not come with flames. decent for mules i guess since shes not that hard to kill if you don't dc. All of the titles from monad also give some stats i think it was 10 all stat 15 att/matt and 5% boss or smth. every title gives the exact same stat and is perm so choose w/e one you think looks the best.
