Botania is where the magic adventure kicks off. So gather a few Botania flowers and make the petal apothecary. It may be worth the time to get the Agricraft versions of the Botania flowers, but that is not required.
Apothecary:
Then make your pure daisies, if you still need a bucket to get water into it see getting the bucket.
From here it is fairly basic progression as normal start of Botania, but here is is for reference:
Diluted Mana pool:
Then some basic generating flora:
Then a regular mana pool:
Once you have that initial setup, then we would want to increase that mana generation with some endoflames:
Then you can start producing your mana items (pearls/steel/glass) which you will need for many other magic recipes.
Note: Manasteel can be made from either steel or iron, however iron is double the mana cost:
Now you have the basics you will need to start the magic adventure!
