When tamed, the Achatina can produce Achatina paste, an alternative to cementing paste, passively when on wandering. You could also collect it when they are moving, their paste/slime will be on the ground shaped in a similar feces ball.
Will only eat Sweet Veggie Cakes even after being tamed! Each cake fills the food by about 200. Poops paste as well as prudces paste in inventory but ceases production once 100 paste is in inventory. Increases organic polymer spoil timer by 3x
1. x3 organic polymer spoil timer
2. Passively produces organic polymer and cementing paste when wandering
3. Poops Cementing paste, even while still, but if still, you must move the achatina to see the paste
It will only produce 100 Achatina paste at a time. Once it holds 100 it stops producing so be sure to collect it often. You can carry these while flying a mountain as well so flying to the artic with one and clubbing penguins and storing the organic polymer in the snail takes advantage of the 3x spoil timer. Pump carry weight and FOOD
Once they have 100 achatina paste in their inventory, they will start producing organic polymer, I believe they make like 10 stacks of 10 organic polymer as their max, so if you want quick polymer for the morning that lasts twice as long, give them 100 achatina paste
Put tamed Achatina in a wooden cage on wander. Then check periodically to take off organic cementing paste (which does not spoil). This prevents picking up thier cementing paste poop but you only get 1 from each poop so not a big loss. Tame 5 to 10 and have a cementing paste farm and great organic polymer storage.
In the wild, the Achatina should not be your first item of prey, as it will crall into it's shell, which can lead to a number of problems. One being the fact that the shell has a very high defense, therefore you could kill yourself due to recoil before the thing even has low health. Another problem is that the Achatina is found in the Swamps and Redwood Forests, some of the more dangerous areas of the ARK, so while attacking the Achatina, other predators have the chance to sneak up on you while your trying to clame your snail supper.
Taming, on the other hand, is very useful for this species, as if set on wondering, can produce Achatina Paste (Cementing Paste produced by the Achatina) and Organic Polymer, which can last up to 3 times as long in the Achatina's inventory. While the Achatina collects the Organic Polymer in it's inventory, the Achatina drops the Achatina Paste that has a low despawn time, and serves as a replacement for it's feces.
In my experience, it's just easier to farm bugs on beelzebufo for cementing paste and use a pelagornis to farm organic polymer from wild/bred kairuku instead of using expensive resources to feed the achatina. I guess if you live in redwoods by a lake with irrigation pipes carrying water up to your trees base with tons of sap taps, then go ahead and tame an army. But if you're like me, and you live on the southern haven, you can't really get the resources needed for achatina efficiently.
You don't need to tame it for it to produce Achatina paste. It will produce it in the wild on its own, so putting it in a pen close to water (wild Achatina needs to be close to water or it will die, as per the Ark wiki) will allow you to take advantage of this. Seeing as the paste is tough to see due to its size, it's recommended to build your pen on sand, or on any other terrain free from clutter.
Note that this has been only tested out on single player.
After tamed they eat berries, so don't think you need loads of veggie cakes after the tame, they also make organic polymer, not sure how it works but I've seen them have a couple stacks in their inventories
Y'all, since once tamed they require a constant supply of cakes, (lil fatties) it is easier to collect paste by having a pen for them and collecting wild ones. No food needed, no upkeep, just tons of free snail poop.
