About this project

What does Undertale modded add?

[[The Images shown are for the most recent version of this mod for Neo Forge]] Older versions of this mod are no longer supported

This mod is based on the game Undertale by Toby Fox. This mod contains new items, tools, blocks, structures, painting, armour, weapons, villager/wandering trader trades and advancements. Most of the items, food, weapons, advancements and tools contain flavor text.

* When using commands the name of the file is ---> testmod <--- so any give and locate command uses this instead of minecraft.

* Most recipes are in the crafting book.

* Check the images for a preview of the mod.

* Decoration blocks are crafted in the stone cutter with amalgamation ingots.

* Because of how MCreator works i can't go back once i update my mod to a newer version of Minecraft so older version will not be updated with new stuff.

* Allom tools require netherite or any modded tool with equal level to mine, to upgrade to allom tools you use the smithing table with a allom smithing template.

* Of note: If you just want the mod with none of the survival aspect's and more leaning towards Undertale mechanics then go check out my other project: Undertale Modded Props. <--(not been updated in a while)

* (the end goal of every adventure is to have fun)
