About this Mod

Backports functional(ish) ominous bottles to Fabric-1.20.1.

Gives Bad Omen effect.
Raid Captains drop when killed.
Brewable to upgrade the effect tier.
Craftable from 8 emeralds and a glass bottle in the middle.

Made for my friends as a learning experience due to no mods like this with fabric compatibility.

Expect horrible quality.
