Every player has a hidden karma score, and the world reacts to it. Helpful actions raise it: planting, trading, taming, breeding, building. Cruel ones lower it: killing animals (babies especially), hurting villagers, and stripping the landscape. The higher your karma, the more the world helps you. The lower it gets, the more it works against you.
Each player starts at 0 karma, stored in their player data and clamped to a range you set in the config. Events move the number up or down. On a timer the plugin checks each online player's tier and applies effects to match it.
High karma:
Low karma:
Neutral: normal vanilla behavior, no effects either way.
When you move into a new tier you get a short message on the action bar.

Paper, Spigot, Bukkit, and Purpur on Minecraft 1.21.1 through 1.21.11 and the 26.1.x line (verified on 26.1.2), Java 21. It only uses the Bukkit/Spigot API, so it runs the same on all four server types.
