Botania's endgame is now also possible, seeing as you can make a beacon.

You will also need to have progressed quite far in ChromatiCraft, however, to craft the other required component for the Guardian Of Gaia, which will drop the Gaia Spirits required for Botania's endgame items.
Just don't forget that you can also summon a Guardian Of Gaia II, but be aware that this one is stronger. It does give some special items however.
