Symbiosis

Two Bulb Shrubs generate naturally in the world, and the mod adds further variants through mutation. In Cherry Groves, Regeneration Bulb Shrubs grow naturally, while Speed Bulb Shrubs are found in Flower Forests. Strength Bulb Shrubs are made by placing Blazethorn Bushes beside Regeneration Bulb Shrubs, and Blazethorn Bushes generate throughout the Nether. Slow Falling Bulb Shrubs come from placing Chorus Flowers beside Speed Bulb Shrubs. After some time, a mutated shrub transforms again.

Players craft an Empty Flask in an L shape from three glass pieces and a leather corner. Right-clicking the flask on a Bulb Shrub fills it with the matching status effect, and a regular Bulb Shrub can be used this way too. Mutated shrubs yield flasks only after a right-click on them. A regular potion brewed in a brewing stand becomes a Filled Flask, and using it halves the potion's duration while halving the consumption. The mod is planned to add more variants over time, with four as the starting point.

Symbiosis runs on client and server, so both the server and every player need it. It is published for NeoForge only, under the MIT License, and the code is open source. Files exist for 1.21 and 1.21.1, with 0.1+1.21.1 for 1.21.1 as the latest release.
