Cost to max all crafting jobs?

[Renalt]

Depends of you are patient. I bought only HQ items from the MB when that particular item popped up on GC turn ins and was also had a star next to it so it was double XP. So that plus double XP for HQ means you would at least gain 1 level a day.

At 20...you would gain a few.

I don't know the exact amount but I think it cost me like 100 million or so?

It's tough to put a number on that if just using gil. Keeping your gear upgraded alone will cost you millions stacked on more millions. MB sharks profit greatly from players seeking convenience, and they are very good at what they do.

A content creator with tons of funds willing to do this on an alt would make for a great video.

Speaking for myself, I've done most of my crafting without spending gil, resorting to my gatherers and retainers to fuel it. Taking the slow, uphill route costs you time instead of gil, but you also make a ton of gil during the process. Enough to cover expenses on things like teleports and shards while keeping the net gain high. I don't think there's really a wrong way to go about, just keep it honest and have fun.

How much gil would it cost me to go 20-90?

Especially if I wanna speed run it via spending gil?

From what others have told me, around 27 million. It'll be a lot cheaper just to take your time. It's not like there is any reward for doing it ASAP.

It can cost you very little to nothing if you're ok with paying it with your time.

For example, on all my alts since the introduction of Firament, I have just spent a couple of days inside the gathering area, turning the items into the materials needed for crafting (and buying or making the materials not obtained from there), which can take you 20-80 with patience.

Then do collectibles 80-90 (where all mats are craftable).

Depending on how willing you are to server/DC hop to buy cheaper mats off different MBs you could be able to break even on 20/25-80 doing Firmament still. It shouldn't cost you too much to do your daily GC turn ins and Ixali tribe dailies to level 20/25. The reason I keep saying 20/25 is because immediately starting Firmament at level 20 is actually tough, but if you wait til 25 you can get away with cheap vendor gear and macro away without a care in the world.

The same can also be said about getting the mats needed for your quests. If you hop around then you should spend more than 150,000ish gil for the mats to get your 1-60 quests done. Also make sure to do the 60-70 quests too since that unlocks an ability for you, and the combined experience from all of 1-70 will get you 2 levels roughly. None of it should be tough at level 80+ since you'll have Trained Eye unlocked which will automatically increase the quality to max on anything 10 or more levels under your crafter level.

From there though it really depends on how fast you want to get everything done. Your weekly custom deliveries will get you 1-2 levels even at 80+ for free. I'd really recommend doing this since it will get you some easy scrips that you can use to purchase free gear that's "decent" at level 80+.

The crystarium/studium delivery quests have some housing item unlocks that you may or may not want, and also story. The experience from those would probably get you 3-5ish levels at level 80+ but you will have to purchase the materials for those quests.

You can turn in leves. Leve turn in items adds up though, so the price depends on the MBs, as well as the MB's pricing on the materials if you choose to craft them yourself. This is also limited to a total of 100 per 2 and a half weeks since you get 3 leves every 12 hours.

You can also turn in collectibles. There's no limit on this, but you won't be able to cheat with trained eye and instantly max the collectability. The price depends on the material prices since you can't just buy the collectibles. You'll have to do this yourself, although with handsaint's gear you should be able to use TeamCraft to make a decent macro for most of it.

Oh and I should also mention that Firmament/Collectibles below level 80 will not give you any decent experience once you hit level 80.

Isn't the reward being able to make a return on the investment?

Not really because max level crafting isn't even the best source of income.
Crafted gear loses value incredibly quickly to the point that you're often better off selling the raw materials (especially tome stone mats) than trying to compete in undercutting wars.
Raid potions and food are decent because they are consumable but sales drop late into the tier and you need decent gear and melds to craft them as they have stat requirements to even start the craft.

On the other hand, you can make money with low level HQ crafter/ gatherer gear (not all slots and level ranges and you have to be careful to never flood the market), housing items of all level ranges and other simple things like crafter syrups, gatherer food, HQ higher level HP potions, spamming collectables for white scrips and selling materia etc
None of that needs max level crafters or decent gear, you just need to cast a wide net instead of trying to focus on a single market like raid pots and look for opportunities like a new ward being released means temporarily higher demand for housing items.

So I think the best thing you can do is level efficiently without spending millions of gil on buying materials to rush it and then noticing that you don't make all that much money at max level.
Use the various avenues for exp: beast tribes, GC turn-ins, collectables, Ishgardian Restoration, levequests, class quests, custom deliveries etc. and combine them depending on what materials you have or want to farm. Rushing everything to 90 isn't as good for making money as you think it is.
