Once I hit ~ 13/14 in Anemos (maybe an hour) there was a nice guy in Aether DC that was working on all weapons so he would collect 14+ players on his team and run through killing things about his level and prepping NMs. Very very good xp. Was out of Anemos in couple hours total. Pagos - get a few levels under your belt then look for groups at your level or just 1-2 above. It helps if you are a healer if they are above your level and tank if you are the highest level. Then Pyros - your only task is to get to 41. At 41 look up reflect farming. I got from 41-47 in about 16 minutes. It definitely felt like cheating but it’s not. Then NM groups from 47-50. Hydatos look for mobs that adapt / mutate as when they do yo get 2-4 x the XP. Some have conditions like weather or time of day. There are resources to figure that out. It’s a toss up here whether it’s faster to group or solo (the right mobs). About 54/55 take any NM you can here. The crystals are much slower so you’ll need more NMs to get your armor and weapons done. It is possible and it is fun. Swap DCs if you join and its a dead group or there are jerks there. One thing about Aether is they are famous for instapulling NMs. I was just at one tonight and the prep group (they are far away - its an unusual one) didnt get to the NM before it was dead. A whole bunch of really terrible people. Anyway, as you get high level if you are having trouble with instapulled NMs before you get there just avoid Aether. It is not always but it can be super terrible.
