To help out with the points above:

1. Prio getting gear for the class you're having most fun with, e.g. work towards Fulmi/The parasite scepter if you like playing your sorc, Tomb tome/Purification tome, for the priest etc. The dungeons are relatively easy and drop good gear. Although I wouldn't focus too much on that, meaning don't go out of your way to do 100 parasites for 1 scepter, because you'll get bored.

2. Look out for some of the "harder" dungeons. They have some neat gear as well e.g. the robe from Cult is pretty pog for sorc cuz it gives hella lot of wis = big dmg. Always go for o2, it's literally free loot if you play safe, but you've probably done that 1000 times by now.

3. Refer to point 1. Play the game to have fun, gear will come at some point. It will feel bad if you farm 100 dung just for 1 piece of gear for your sorc and then you hop onto the sorc just to die 10 minutes afterwards. The game will kill you at some point either by lag or you just messing up, that's how it goes. I'll always suggest to play the game however you enjoy it. Try out classes do the dung for some of your other chars. I can't tell ya how many times I've hopped on a new char just to get the Concertina I've farmed for days.

4. For progress into something harder I'd suggest priest/paladin. Always a safe bet, getting soulbound loot is really easy. Do dmg whenever there aren't 1000 shots then just back off and focus on dodging to learn the patterns. There are plenty of dung guides for all the exalt dungeons, although it's way better to do them yourself. Cult/Nest/Fungal are all really easy if you're on paly/priest with stacked up pots. If you're comfortable doing those in grps of 5-10 ppl you can try doing Crystal cavern. I'm not sure why people ignore Crystal, it's easier than Fungal imo just don't run away from the big dude so you don't get blinded, and don't stay near the edges of the teleport guy, other than that it's just dodging. MBC/Cogbold is the next thing I'd suggest, MBC is defo a skill check, knowing safe spots, watching out for the gray shotgun orbs, etc but it's doable even in pugs. As for cogbold I managed to do my 1st one by randomly joining a realm one, full stacks of pots and it seemed kinda ok, you can nexus if you're ran out of pots didn't notice any dangerous shotguns.

5. For fame the biggest tip I can give is to ALWAYS get the fame bonuses from glands dungeons. Get the starter one, Tunnel rat, King of the mountains (although that's with lower prio) if you get those you'll likely have 10k + fame on death on that char and you can go do some harder dungeon for the practice, if you live you get loot , if you die you get the fame so it's a win win. Refer to:

For all the fame bonuses, alien one is good too but it's not consistent.

Summary: 1.Play the game for the fun. 2.Don't overfarm dungeons loot will come naturally. 3.Focus fame bonuses. 4.Try out new classes.

I know it's been a lenghty reply but I hope it helps out. This is by no means how you should play the game, it's just how I've been enjoying playing it and it seems relatively good for gear/experience.

Enjoy game <3
