RUTHLESS
by WebCreature
Ruthless is a Forge mod for 1.20.1 that makes hostile mobs harder by reworking the stats, behaviour and attacks of vanilla zombies, skeletons and other enemies.
What it does
Zombies in Ruthless run faster, notice players from much further away, spawn more often with tools and can break through blocks with pickaxes. They also use totems. Skeletons move much faster, see slightly further and sometimes spawn holding swords. Creepers and other hostile mobs receive new attacks, and some mobs can rely on one another to work together, so the overall challenge grows well beyond the vanilla settings.
Most of the changes are tied to config values, and many can be turned off in-game through a config mod. The author describes the mod as an overhaul of the vanilla hostile roster that also touches a few animals, golems and bosses, and plans further content that alters mob behaviour. The mod is in alpha, and the author warns that it may be buggy.
Ruthless requires Forge for 1.20.1 and runs on the client and the server, so both sides need it. It is published only for 1.20.1 and is not open source; it is released under All rights reserved.

What the author says
Ruthless has plans to add more content than simply changing mob behaviour. Ruthless overhauls vanilla hostile enemies by giving them new attacks, overhauling their entire statistics and making them just generally way stronger than in vanilla. Some mobs will have brand new things such as effects, items, blocks, and…
