welcome to the master class.
...until you can get your hands on a dm, I'll advise you to get an Iron Faust as soon as possible. It's pretty strong and it will help you alot in the upcoming events. Like DM's special, IF does have infinite vertical reach allowing you to even hit bosses in air. Besides it's super accurate, it won't even need hit. The special (unreduced havok) is situational but can be useful sometimes especially if your soloing. IF was my first good weapon here and it helped me alot.
something else that didn't get mentioned yet is twin blaze. It casts low lvl gifoie and it has so many uses (stopping delibters, Zus, setting up traps etc.) that every cast should have one. It's really easy to get since it's a bpd reward.
that is all. spam traps.
