Before you can finish off the earlygame, you will need to do some more Botania, by way of making a Runic Altar.
This requires Blood Runes from Blood Magic, a Witchery Attuned Stone and some basic Botania materials.

To start crafting runes, you will need Arcane Ingots from Aura Cascade, some more basic Botania items, some "easy" to find ChromatiCraft materials and a Tier 2 Blood Altar.
About those ChromatiCraft materials... you might have trouble finding some of them. Here is a hint:
"To bind the powers of fire and water to a livingrock slate, you first need materials attuned to these elements.
Finding them may prove a challenge however, unless you have a deep understanding of these elements.
Therefore it might be good to search out locations where these elements are concentrated, to learn more about them."

The only exception to this pattern for the basic runes is the Rune of Mana, which does not require you to upgrade your Blood Altar just yet.

And with that, you have officially finished the earlygame! Congratulations!
