Difficulty Overhauled
by The Tavern
Difficulty Overhauled changes how zombies, spiders, Endermen and Illagers behave, adding new mechanics to vanilla mobs for Fabric players and servers.
What it does
Zombies can break blocks near their path, but only blocks within a strength tier. Four block tags (weak, tough, strong and resolute) set which blocks a zombie can break, and a zombie may need a tool or a second condition to break a tougher one. Whether a zombie is strong is decided when it spawns and is not saved, and the chance depends on difficulty: 10% on Normal, 15% on Hard and 20% on the higher setting. Zombies also gain a base level of block breaking, and the breaking of containers can change with the difficulty.
Spiders can spit webs at a player from a few seconds away. The web is a placed block that cannot be obtained, and it can replace most blocks, sometimes landing above the player's head as a transparent block like a stair. Placed webs decay over time through random ticks. Endermen sometimes throw a projectile that teleports them to a target within a similar range, using logic similar to chorus fruit. Illagers become enraged when a patrol leader dies, gaining a status effect that raises movement speed and damage, and the blaze-style fireball projectile is found only in the creative menu.
Beds can be set to change how night works. By default sleeping does not skip the night, but the enableSleepSkip game rule set to true restores vanilla night skipping. Another rule, enableSleepSpeed, makes sleeping cause time to tick a bit faster. A player asleep in a bed slowly heals through natural regeneration, and the gamerule controls that behavior. The mod is supported on Fabric only.
Key features
Strength-tiered block breaking
Zombies break blocks by tier, with weak blocks open to all and resolute blocks out of reach.
Web-spitting spiders
Spiders spit a web at players from a distance, and the placed web later decays over time.
Teleporting Endermen
Endermen sometimes throw a projectile and teleport to a target within a similar range.
Enraged Illagers
A patrol leader's death enrages nearby Illagers with a status effect that boosts speed and damage.
