arcys lunar moon
by zekon.kitkat
Arcy's Lunar Moon adds a lunar cycle, a red sun event, toxic rain and TNT rainfall to a Forge world for 1.20.1, with custom items meant for surviving those events.
What it does
The mod changes the sky and the night. Lunar moon phases follow a cycle that affects world mechanics and nighttime difficulty, while a red sun event alters the atmosphere and the gameplay loop for a period. Two weather variants are included: toxic rain, which calls for shelter and protective gear, and a rare TNT rainfall in which primed explosives drop across the landscape.
New tools, materials and consumables are added for getting through these events, and the author plans expanded equipment sets for environmental protection, extra weather archetypes and mob variants that appear only during certain celestial events. Some of these features are described as temporary, and the author states the mod is updated with community feedback. Servers and players both run it, and it is released under the Apache License 2.0 and is not open source. It is published for Forge 1.20.1 only, as version 1.0.0.
