WaterCrits-mod

In vanilla Minecraft, a player swimming submerged cannot land a critical hit. WaterCrits reverses that logic, so only critical hits apply water-related rules, and jump and fall attacks that land in water deal the standard 1.5x critical damage multiplier.

Normal melee attacks made while submerged or touching water are silently cancelled, and a configurable warning message can be shown to the attacker. Sweep attacks are blocked too, so the area-of-effect sweep damage does not apply from a submerged attacker. Cooldown thresholds, these toggles and the action-bar or chat messages are all set in a generated config file.

The release includes both a Fabric mod for clients and servers and a Server Plugin for Spigot and Paper. The plugin adapts support for legacy versions. The mod is released under the MIT License and its source code is public, and it is listed for 1.21.11 only.
