Deep Overworld
I don't know my version or loader



Main Description
Deep Overworld is a mod that adds deepslate to the surface of the overworld! It does that through a biome called the "Deep Forest". The "Deep Forest" also has "Deep Trees" that contain wood similar to warped wood but with a purple outside. The deep trees contain a weird block that acts like the leaves of the tree called "Decayed Grasin". It is actually a part of a family of "Grasin". "Grasin" is a unique type of poison that gives you the "Grasin Poisoning" effect when picked up. Don't worry, though! You can protect yourself with the "Grasin Protection" enchantment that you can put on your helmet. There are three types of "Grasin" A, B and C, each giving a different level of the "Grasin Poisoning" effect. Each level needs a different level of the enchantment to protect you (EX: "Grasin Poisoning II" needs "Grasin Protection II"). "Grasin B" and "Grasin C" can generate in patches. "Grasin A" is obtainable through breaking "Decayed Grasin" without silk touch. You can also poison your friend by brewing "Grasin Poisoning" potions with their respecive "Grasins" and an "Awkward" potion (EX: "Grasin B" gives a potion of "Grasin Poisoning II")!
NOTE: The potions and enchantment are not in the mod's creative mode tabe
Changelog (Version 1.1.0)
