Any mod not on the whitelist that modifies game behavior is prohibited. Back to Rules
Note: If we find any mods that are not found on Modrinth, and we don't know anything about them, we will count them as illegal.
Important. Extreme Mechanics Mods: Any mod that extends vanilla mechanics beyond their intended limits (e.g., FOV past the default maximum, extended render distance, or any client side value exceeding what vanilla allows) is treated as a blacklisted modification. If the mod author themselves warns that their mod can be used to see through walls at certain settings, that mod is banned.
