@Stinkyy
you have two possibilitys of gearing
1 is astral and if you are a new player i strongly recommend doing it
find a group and venture in the wide astral to find treasures
this is something like a trademark of this game and you should use it
2 is umoira there you farm mobs for loot, which give you the option too buy gearboxes and its the easyer way cuz you dont need a full grp and you can die all day long without consequences (in astral you just have a certain amount of death per island then its game over)
from those possibilitys astral will bring you more loot if you are successful but it you manage to find a grp of nice ppl who are willigly to carry you to a higher farming zone (there are 4 green,blue,epic,legend) then farming will be better cuz if you use legend upgraders on green items you will get like 300% per upgrade and will be abte to go full legend in a really short time (its less fun but more effizient
)
