Christmas Spirit: Rewoven

Players can gift presents, decorate Christmas trees and bake holiday sweets. The gift system lets a player craft an unwrapped present, choose its color and the date it may be opened, then place it for another player. Each day a player logs in, Santa can leave a present with a random surprise, and the chance of a better item rises when several Holiday Spirit effects stack.

Behavior is tracked through a Naughty effect. Harming animals such as cats or dogs adds to it, and at five stacks Santa writes the player onto his Naughty List, so Lumps of Coal replace the usual presents. A Jack Frost trade gives access to Frostbourne Ingots for crafting armor. Snow and ice generate in biomes outside oceans, and the default ambient music can be replaced with royalty-free Christmas songs by Kevin MacLeod. The feature can be turned off in the config.

The mod is published for 1.16.4 and 1.18 with snapshot builds, and it runs on the client and the server. Both the server and every player need it. The source code and issue tracker are public, but the code is licensed as All rights reserved, so it is not open source.
