Hello, Mike here.
Most people hate hunting because it's too dull, not enough money, botted too much, or just plain stupid. As if! It's one of the most profitable yet relatively fast skill in the game.
There's multiple ways to level but I'm only going to do grenwalls.
69 Summoning for Fruit Bat
77 Hunter minimum (I recommend 85)
Tiny elf crystals
some money for bat pouches and scrolls.
500-1.5k spikes/hr (600k-2m/hr)
I do farm trips every 2 bats since they last 45 minutes each.
If you don't want to farm, here's the long haul one.
any more than that and your space becomes limited.
Path to get to best place to hunt grenwalls/pawya's:
Going from lletya is the best way if you have tiny elf crystals.
Tyras's camp isn't too bad charting a ship there.
The best setup I have found through trial and error is still the X. Just larger since you don't want to scare the pawya's or freeze the grenwall's.
Red are Grenwall spawns and green are pawya spawns. The box in the middle is for wayward catches (happens a lot since their random movements are really random).
I put pawya meat in the northwest, center, and south east box (you will catch more pawyas than grenwalls) then papaya's in the northeast and south west boxes. Stand where I am currently standing to be away from the most traps. They don't come near you there often.
There's a couple tricks involved in setting boxes and obtaining fruit. When you click to set a box, immediately click summoning icon (which should be set to cast special ability). The animations stack and a papaya fruit will fall most of the time (whenever fruit falls, there is ALWAYS a papaya, if one falls, it's a papaya. sometimes this fails and nothing will fall).
Another tip is that papaya fruits falling from fruit bat scroll are the most west then south fruit. If there's 2 fruits that fall, and there's one that falls west of you and the other south, the one west of you will be the papaya. If 4 fall in each corner around you, the one in the south west corner will be papaya. It takes a west priority then south priority if a fruit is in the same west column.
Also, there's a reason I'm on low detail and small screened, easier clicking. It's easier to locate the graphic squares to set boxes and less distance for the mouse to travel from inventory/summoning icon/box.
