Sculk Sickness
by RosiePies
Sculk Sickness is a Forge world generation mod that adds a sculk infection with four growth stages and a cure, first published in July 2024.
What it does
Sculk blossoms are a new block added by the mod, and they act as a catalyst for the infection. A player who stays too long in the deep dark risks catching it. The sickness passes through four growth states, and the last one releases spores that spread the infection to nearby creatures and players.
An infected player can become uninfected by completing a journey to create an Ambrosia Herb, which is then eaten to cure the sickness. A player who cannot be cured dies with the effect, and the corpse spreads sculk that grows new blossoms, so the cycle repeats. Deeper and Darker and Sculk Horde are optional dependencies, and the mod runs on the server alone, so players join without installing anything. Files are published for Forge, for 1.19.2 – 1.20.6 in seven release versions, under the MIT License, and the source code is open source.
