Im Jaela and I'm also on the Hades server. I'm a level 67 Thief, and I'm willing to offer any help if you happen to catch me when I'm online.
Your best bet is to kill everything you can right outside the starting city, sell a bunch of it to the NPCs, and save about 2000gil to buy the first set of leather armor. For warriors the upgrades you should get should roughly follow this chain:
Upgrade those to the left first, those to the right are least important.
Weapons <---- Armor <---- Stat enhancing rings ----> All other items
As a warrior during the early jobs you'll need to be able to solo until at least level 10. A great weapon and a good set of armor will help you do just that. Stat enhancing rings and other items dont really help much until after level 10. I estimate to a person completely new at the game it should take between 1-2 weeks to make it to level 10.
At level 18 you should finish your subjob quest, pick a subjob that a melee class would use. Red Mage, White mage, and Black mage are not recommended Melee subjobs.
At level 30, you probably want to unlock NIN and level it to 30 or so for subbing it, the utsusemi quest might be a good idea as well. Afterwards yo might want to swap your main job to Paladin for a more serious tanking experience with a spruce of White magic, or DRK for a more Damage Dealing experience with a bit of Black magic.
I personally also recommend playing Red Mage, because they can melee, cast black magic, and white magic. Making them jacks of all trades. Playing a few levels of RDM will give you the basis for most of the mage jobs.
Send me a tell in the game. Good luck! Stay Alive! Dont get Discouraged.
If you happen to want to know where you should hang around to get each level, heres a good guideline:
1-9: West/East Ronfuare
10-13: La Thiene Plateau
14-20: Valkrum Dunes
21-25: Qufim Island
At 25 you should get the Kazham airship airship pass by getting the following items:
Giddeus Chest Key
Ghelsba Chest Key
Palborough Chest Key
Chances are you'll be able to find each if you ask me for help in game. Feel free to. I have lots of free time.
26-29: Yuhtunga Jungle
30-33: Yhoator Jungle
34-37: Garliage Citadel
And so on. If you have any questions just send me a tell.
Jaela
