OK for the newcomers coming in here are my tips that might help you
First message me in game, say hi or whatever, I'll pass you 10,000 gil each so you can guys have a a little bit of gil for stuff
I'm Grave Robber on Ultros (same as GAF name with the X only missing)
Next, I know you just started out, learn to start eating food right away, it will give you a 3% bonus, not much, but I mean over time it adds up
Buy the cheapest item from the vendor like boiled eggs for DD's, flatbreads if you are tanking class, and raisins for casting
They aren't much, can get grab a stack of 99 very cheap
They last 30 minutes, unless you die, then it's gone
*If still pricey let me know in game when I'm on, I'll buy it for ya*
Now for the first 10 levels, solo it, learn some of the skills/mechanics of your class
In between you'll see icon on your map with a purple octagon shield icon, or if you are nearing an area where it's happening, those are FATEs
These are you world events that take place at certain times (most are 10-15 minutes, the higher tiers ones are 1 hour+)
This where you gain chunks of XP
Never solo in FATE's, always shout to party up, why?, the more people in party, the more XP you gain off the adds (cause you will be killing them quickly and more will be respawning) + if solo boss, you need to do 30% damage to get Gold Ranking, so if you have party members, they help achieve it easier than soloing it
Always try to get Gold, at the start you'll gain XP + Gil, but when you reach the level 25 quests of the main storyline, you'll get to join one of the three grand companies, and then seals will become your go to collecting (gear, weapons, items)
Dungeons are also a good XP helper, with 2.1 patch (December 17th) they will be getting a huge buff, at the moment FATEs are the go to for XP
Dungeons can be repeated many time over for gear to slot in or if your really dedicated miser and don't want to splurge at all, just grab everything possible
If you need to make a little money from the get go, once you get at least a class up to 20, try your hand at botany + mining
It maybe boring to some, but at the lower levels, shards can make you decent gil
Fire + Wind + Earth get eaten up like no tomorrow
If you at least invest a hour or two to harvesting, you will have enough items ready to sell for your retainer (your personal seller who sells stuff on the marke0tboard on you behalf)
You can go put stuff on the market, while you go level up and by the time you are done, you should some nice gil waiting for you
Always check market history on how items are selling, never undercut by a huge margin
A gill or two OK, but not something like 50+ gil per
If you need help are stuck, message me, I'm always doing something, so I;m always on most of the day
Hell if you need a buddy to play with, I have a level 10 arcanist and 15 whm that come help ya
Other DD classes are 20+, MRD/DRG are 30+, so I have classes in range to help with whatever you need for the coming weeks
*ALSO VERY FUCKING IMPORTANT*
Don't hesitate to tell your party members you are new, you need some help understanding some stuff, most are helpful, some will always be dicks no matter what
If you need to get into crafting, I say wait till you at least get a little holding of the game and start sinking gil into crafting
Keep some gear for other classes/jobs, it's stupid to sell gear in the start or convert into materia (that's a whole different beast), cause most overlap for classes
If you get to 20, let me know, whatever your class, I'll try to craft ya rings with a vit+ materia for you to enjoy for at least 10+ levels
Try to keep the free potions from side-quests, can really help you in a bind if you got no way to heal or need an insta hp gain without casting a speall
Hope some of this info helps
PS: Just running around the map and surveying it gives you XP, so be an adventurer and just say fuck it and run around and see how far you can reach before eating it, you might build up 10K+ xp just from wandering around and unlocking the whole map
There are many many maps to survey
GAF is quite huge, I think 1st day of early phase, most of us in there had already gotten the FC to Rank 5 that day lol
GAF has many members, so that insignia of the guild is everywhere, I wouldn't be surprised that 25% of the server is GAF running around at a given time
I see them everywhere
