You will want to bring a scout/pulse rifle for oracles at Aethon, an energy fusion, a linear fusion/rocket launcher. You will need something to stun overloads, bow or sword, make sure you have unlocked the seasonal mod to stun overloads with the respective weapon. Partical deconstruction mod from the artifact will help with boss DPS. If you LFG for your group, look for "willing to teach", or make your own post with "need someone to teach/sherpa". I might take awhile to find/make a group, so be patient. Watch a few raid videos to get familiar with the encounters. Listen and follow the advice of your sherpa. Be honest when you make a mistake. If you don't understand an encounter mechanic, ask questions. Most of all, have fun!
