Module Type	Stand Alone
Created by	Thanathor
Compatible MC Versions	1.19

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 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.

Items

Obtaining and Identification

Custom weapons and armour are dropped with the same rate as naturally spawned equipment at 8.5%, scaling with looting. Any items dropped like this will be prefixed with "Unidentified" and will work identical to their vanilla counterpart.

Unidentified items can be identified to unlock their special effects. Weapons are always identified on their first use damaging any mob or player while armour needs its activation requirement to be fulfilled (armour with the "equipped" requirement is identified immediately).

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 +2 health, capped at +30
• 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.
