Nightmare Mobs
Nightmare Mobs makes existing monsters much stronger on Forge for 1.20.1, with raised health, upgraded gear and faster attacks for some mobs.
What it does
The mod raises the health of mobs and gives some of them weapons and armor, while certain mobs also attack faster. The changes can be combined with the level difficulty game rule, which the author recommends leaving false, since setting it to true makes mobs considerably stronger. Client and server both need the mod. Files are released for Forge only, for 1.20.1, under the Apache License 2.0, and the mod is not open source.
Key features
Stronger mobs
Mobs gain a substantial increase in strength, making ordinary encounters harder for players.
Higher mob health
Monsters start with more health, so they take longer to defeat in fights.
Armed and armored mobs
Some mobs are equipped with weapons and armor, and certain mobs attack more quickly.
