The Birch Expansion
I don't know my version or loader







I hope y'all like this, because i put a lot of effort into this : )
This mod expands on the use of Birch wood, with special Birch Wood tools and Swords.
With the Birch Swords you can make serrated swords, which once you add a leather handle, can be upgraded, dyed and redyed.
Also there are some flowers and plants to be found, like onions, ghost peppers, Chrysanthemums, Marigolds, etc.
And once you get access to a secret tool, you can use it to make stacks of materials, which you'll want to use for the overpowered Birch tools and Armor.
This is both a passion project and "Kitchen" mod, because of the unbalanced weapons and tools, references, and personal additions.
My last mod i made for personal use got dusted when i accidentally reformatted the usb-drive it was on, and i had been working on it for 3 years, and was meaning to upload it.
The "Clumps of Rotten Flesh" and "Block of Rotten Flesh Clumps" originated from that mod, which at the time was just called "Jen's Mod" (stupid, ik)
