Rush. Air collection.
Making money. Air gathering.
Gathering air resources is a very good way to earn money, allowing you to accumulate a lot of money and useful crafting resources (needed for making weapons, armor, and jewelry) with minimal time investment if you know the best gathering spots.
You gain the initial air gathering skill at level 10 when you become a Daev, enabling you to collect resources that require skill (1). They are abundantly available above the Altgard Castle. It's best to gather them by flying off the ground, and they are very easy to find. Then, after obtaining skill (25), you can switch to higher crystals, which are better gathered from the castle walls. You can find one crystal (25) and change channels (there are 7 in Altgard; by the time you gather a crystal on channels 2, 3, and 4, the crystal on channel 1 will respawn).
You can change channels in the Start menu by selecting service >>> change channel.
Once you level gathering up to 50, you can move to Impetus, where it's easy to gather crystals at 50 from the ground and later 75 from the central structure by changing channels. Then, ascend to the upper platform of Impetus and step onto the ledge to be under a crystal at 100. It's best to upgrade your skill here to at least 125, but this is a very favorable spot; the next stage will be challenging.
The difficult stage of leveling gathering from 125-175 occurs without changing channels in the city of Morheim, where there are usually a lot of people, and in the evening, crystals must be practically snatched from other gatherers. 125 can be found at ground level, while 150 and 175 are better remembered by location and caught along the route from the ledges near which they are found.
Later, from 175 to 225, it's convenient to gather in Beluslan or Abyss. In Beluslan, you can gather 175 from the ground, 200 around the hills near the city, and 225 on the city walls. You can gather there and beyond, but resources are scarce and widely scattered.
From 225, it's great to gather resources around the Temple of Fire in Morheim (the center of the map). It's worth leveling there up to 275. There are many crystals, and they are closely located. You can even map out a route and gather continuously.)
At 275, there is a huge plantation above the Asmodian citadel, then after reaching 300, head to the ToF and gather resources along the route up to 325 before returning to the Asmodian citadel in Abyss to finish 350 there.
Above 350, you continue leveling in the Lighthouse. There are a lot of resources right at the ceiling. Go for it.
In fact, I leveled gathering in Elysea while waiting for NPC Rasberg.
To facilitate gathering, there are radar hats that are sold in the capital, in the resource gatherer building on Crafter's Street. As you enter the street, it's the first entrance on the right.
Additionally, items that provide bonuses to flight time and flight speed are used to ease gathering. Armor, jewelry, wings, and mana stones.
