Compound V Unofficial Port

Taking Compound V grants a random power, and some powers are passive while others are activated with the V key, which can be rebound. Compound V powers give a baseline of damage reduction and a strength boost, and a rare occasion applies a negative effect. Drinking milk does not cure Compound V, which is noted in the author text as an important point. A temporary version, Temp V, turns up rarely in several structures and locations that players can explore.

The port adds Compound V Boys ported to 1.21.11 with Tips abilities and includes a set of tweaks meant to replicate the original mod as closely as possible. An in-depth configuration controls which powers can be obtained and the chances of receiving a bad effect or finding Compound V more often. The mod is published for Fabric only, for 1.21.11, with the latest file 2.7.3+1.21.11 dated 2026-07-23. A server running it needs every connecting player to have it too.
