This module adds custom modifiers to armour, weapons, and mobs as well as a ramping difficulty curve the longer you survive.

Combat Expanded

Module Type	Stand Alone
Created by	Thanathor
Compatible MC Versions	1.19.2, 1.20+

Features

Combat Expanded expands on the game's difficulty. Mobs will be given additional stats and gear scaling over time. This gear can be dropped for the player as Unidentified weapons or armour.

Mobs

As a player stays alive in the world for longer the mobs that spawn around them will grow in strength. Mobs will spawn with higher health, damage, movement speed and with better armour and weapons.

Mobs will also receive additional bonusses depending on what biome they spawn in.

Spawners

Mobs spawned from spawners do not benefit from any modifiers. Mobs are considered spawner spawns if they spawn in the air.

Blaze, Drowned, Slimes, Magma Cubes, Phantoms, Shulkers, Ghasts, Guardians, and Elder Guardians will gain modifiers even if spawned from a spawner.

Zombie Leaders

Zombie Leaders that spawn are replaced with zombies that have highly increased stats and much better gear than ordinary zombies.

In addition Zombie Leaders will be equipped with a shield enchanted with Thorns III Unbreaking V.

All of the equipment has a high chance of being dropped on death.

Items

Obtaining and Identification

Custom armour and weapons are dropped at 8.5% and 20% respectively, scaling with looting. Any items dropped like this will be prefixed with "Unidentified" and work identical to their vanilla counterparts.

Unidentified items can be identified to unlock their special effects. Weapons are identified on their first use and armour when equipped.

On identification a sound will play, and the item will restore half of its lost durability, the Unidentified prefix is replaced with the name of the modifier (unless the item was renamed).

Technical Details

Difficulty Calculation

Each player has their own Difficulty Score, based on the Minecraft days they have spent in the world in total (Dt) and the Minecraft days they have spent since their last death (Da). Both of these values are capped at 10.

The formula for the Difficulty Score depends on the world difficulty.

Easyː ROUND((Dt*Ds-4)/14), Difficulty Score is capped at 7

Normalː ROUND((Dt*Ds-2)/13), Difficulty Score is capped at 8

Hardː ROUND((Dt*Ds)/10), Difficulty Score is capped at 10

Mob Changes

Mobs can be given bonus points (italicized) to some of their stats, these points are then randomized between 0 and their current value based on normal distribution and stat buffs are applied:

• Max Health: each point corresponds with +1 health, capped at +15
• Attack Damage: each point corresponds with +0.5 damage, capped at +5.5
• Movement Speed: each point corresponds with +2% speed, capped at +30%
• Armour: each point corresponds with +1 armour, capped at +7
• Armour Toughness: each point corresponds with +5 toughness, capped at +35

Mobs will use the Difficulty Score of the nearest player upon spawning.

Underlined stat changes are exact and will not be randomised.

Zombie Reinforcements

Zombies spawned from reinforcements only have 1/4th the normal droprate. This droprate won't be increased by any other effects such as Difficulty level 11.
