Cybernetics: Cyberchems

Cyberchems augments biology with chemistry. It adds six cyberchemical modifiers, each taken as a substance that changes the player for a period. One modifier raises speed, strength, size and effects, and another grants a dodge chance capped at 90% along with immunity to wither. A black lace substance negates negative effects, at a cost in humanity, and a stim that can teleport the player to a random spot within a 64 by 64 grid.

The modifiers carry drawbacks as well. Roid Stim has a 10% chance of causing addiction when used, and addiction leaves the user shaky, weak and unable to fight. Addiction cannot be cleared through normal means: it wears off after 7 game days, or a full day of weakness and nausea clears it. Addiction also changes how villagers behave toward the player. The mod requires Cybernetics, which provides the implant system the modifiers are built around, and it runs on NeoForge for 1.21.1 only.

Servers that run it need every player to install it too. Cyberchems is open source under the MIT License, with its source code public. The author does not plan frequent updates, which are mostly bug fixes, but intends to add more cyberchems and welcomes suggestions for them.
