I'm not sure how much you know about it already, or if you have done any yet so I'll give the essentials from my experience.
If you plan on catching each type of jadinko, you need to bring:
- Coins to buy the plant traps, noose wand and flower seeds
- Banana, Apple, Orange seeds
- Plant pot (leprechaun is there for other farming tools)
- Hatchet to chop down fruit tree
All the other seeds are gotten from catching the jadinkos, so to get started you just need to start catching the jadinkos you can. The best option at the beginning would be catching diseased jadinkos because they can give you any type of seed, and you need their corrupt vine to create juju hunter potions which are needed to be poured on the flower patch to catch some other types of jadinkos. To attract these, you need a banana tree planted, and a boneyard built in the habitat and then you do the tracking to the south. If you get a good collection of corrupt vines but not many seeds, it would probably be worth switching to common jadinkos to the north caught by the plant traps because they can be caught much faster yielding a better chance of receiving seeds.
Catching one of every normal jadinko is necessary for 2 weeks to get the witchdoctor robes camo and you must catch all the god jadinkos once to get the mask. The god jadinkos are different every week so you have to cycle through all the combinations of different things to put in each of the patches that matter (flower, bush, tree, and habitat) till you get a message saying they have been attracted. Having nothing in one of these patches is also a possible solution to finding how to attract the god jadinkos, so be aware of that before switching between things too fast, especially the bush because those seeds are harder to come by from the jadinkos. To attract god jadinkos, the flower patch must also be treated with hunter potion.
Other than getting the witchdoctor set, it's not useful to catch most types of jadinkos because the bonus xp you get for doing it is not worth it. The only potions really worth getting in my view are the farming, mining, and hunter potions.
