Hello all Diablo 2 vet here

New to path of exile, I would like any advice offered. I have 3 characters made already in Infliction season I purchased the 110 dollar supporter pack I am definitely invested have well over 300hrs of just having fun so any advice would be appreciated thanks 😊 in advanced haha.

You don't have any challenges completed, so I assume you are playing in the Standard league. The Affliction league mechanic is not available in Standard, so if you wanted to join the majority of the playerbase in Affliction league, you might enjoy it more.

Then again, you might not, as the economy is a bit weird because of the league mechanic.

Your character tab is hidden. That's an account setting you can change... left click your account name at the very top left, then Edit privacy settings on the right. Then uncheck the Hide characters box.

Unhide it and say more about what you are enjoying and not, whether you have specific goals or problems, etc.
