Custom Potions
Custom Potions lets players merge two potions into one on an anvil, so a single bottle can carry the effects of both.
What it does
Placing two potions on an anvil combines them into a finished potion that holds the effects of both, which saves inventory space. The feature is a server-side Fabric mod, so only the server needs it and players join without installing anything. Builds are published for Fabric across seven release versions, 1.21 – 1.21.8, under All rights reserved.
