Skins/gold/gems
Well these are some really common non specific questions. Best thing to buy with gems is well, whatever you want. Is that armor, a piece of amror, gathering tools, bl keys, makeovers… you name it. It depends on you and your preferabillity ot vanity vs useful things.
Best way to earn gold is, well selling materials you gather or get as a drop. And you can make a decent with crafting sometimes just look ul at tp sometimes to see supply and demand.
And for skins, again, totally up to you and your chars look
- chopper fed salvage o matic/charslots
- € -> Gems -> Gold is the fastest method to make gold
- you’ll want some nice looking weapon, without attracting attention = basic skin
or you want some uber flashy weapon to annoy other gamer = legendary
