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

Combat Expanded

Module TypeStand Alone
Created byThanathor
Compatible MC Versions1.19.2, 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 with special modifiers that alter the players stats and abilities.

Home Bed

Players can designate a bed as a "Home Bed" by sleeping in it. Only the last bed slept in by any player can be a Home Bed. While a player is online their Home Bed serves as a beacon that lowers difficulty in an area of 128 blocks around it. Only one Home Bed can affect an area at a time.

Natural Regeneration

Combat Expanded disables normal Regeneration. Instead player will regenerate half a heart every 0.8 seconds as long as they are out of combat.

Players will enter combat when:

  • Being damaged by a mob, explosions, the Wither effect (12 seconds)
  • Drowning, Falling, Lava, Poison (2.4 seconds)
  • If on fire regeneration will happen every 3.6 instead of 0.8 seconds, but will not enter combat

Killing an entity will immediately exit combat until damaged again.

Item Modifiers

Custom armor and weapons are dropped at 8.5% and 20% respectively, scaling with looting. Any items dropped like this will be prefixed with a special modifier.

Technical Details

Player Difficulty

Each player has their own Player Difficulty, which is calculated every 5 minutes or on respawn.

Player Difficulty = Playtime * (1 - Death Multiplier) * World Difficulty, where

Playtime: goes up by 1 every 5 minutes a player is online, up to 100.

Death Multiplier: is calculated on death by: Death Multiplier = Death Multiplier * 0.75 + 0.2, every time difficulty is calculated it is reduced by 0.01 for every 5 minutes since the last death.

World Difficulty: is based on world difficulty: 0.3 for easy, 0.4 for medium and 0.5 for hard

Mob Difficulty

When a mob spawns it will be assigned a Mob Difficulty of its own to modify its stats.

Mob Difficulty = Player Difficulty * Difficulty Modifier + Random Offset + Illager Bonus, where

Player Difficulty: Difficulty taken from the closest player

Difficulty Modifier: is calculated based on the environment where the mob spawned:

  • Start with a random value between -0.1 - 0.1
  • If it's raining: +0.2
  • If the mob spawned on the surface and it is night time: +0.1 for crescent moon, +0.2 for quarter moon, +0.3 for gibbous moon or +0.4 for a full moon
  • If mob spawned underground (Dark): +0.3
  • If in Mountainous biomes: +0.2
  • If an active Home Bed is within 128 blocks: -0.4

Random Offset: a random value between -5 and 5

Illager Bonus: applied to Illagers under certain conditions:

  • Illager patrol leaders: +10
  • Illager/Ravager in a raid: +3*(raid wave)

A mobs Difficulty is then used to calculate their stats. Each mobs has their own Stat Page, mobs final stats are calculated as follows using those scores:

Max Health = ((0.5*score) + BINOM.DIST(n=0.5*score, p=0.5)) * (Mob Difficulty/100)

Attack Damage = ((0.15*score) + 0.35*RAND.BETWEEN(0,score) + BINOM.DIST(n=0.5*score, p=0.5)) * (Mob Difficulty/100) * 0.1, cannot exceed the damage cap

Movement Speed = 0.5*RAND.BETWEEN(0,score) + BINOM.DIST(n=0.5*score, p=0.5)) * (Mob Difficulty/100), in percentages

Armor = ((0.25*score) + 0.25*RAND.BETWEEN(0,score) + BINOM.DIST(n=0.5*score, p=0.5)) * (Mob Difficulty/100)

Armor Toughness = ((0.25*score) + 0.75*RAND.BETWEEN(0,score)) * (Mob Difficulty/100)

Mob Modifiers

If the chance for a modifier is underlined it scales up with Mob Difficulty, the displayed chance is for 100 Mob Difficulty, e.g. an 80% chance at 100 Mob Difficulty would be a 40% chance at 50 Mob Difficulty.

History

Version Date Change
1.19 22 Aug 2022 Released Combat Expanded
1.20 23 Sep 2023 Updated for 1.20

Module is no longer experimental

1.20.4 25 Jan 2024 Updated for 1.20.4

Introduced the Difficulty Update

Previous Versions

MC 1.20.2 Version

In the 1.20 version Difficulty was calculated in a much simpler way, ranging from 1-10, going up by one for every Minecraft day a player survived.

The 1.20.4 Difficulty Update reworked almost all of how mob stats were calculated to provide a smoother and slower increase in difficulty while making it easier to balance.

Unidentified items were also removed after this version, instead items are "identified" as soon as they drop..

MC 1.19 Version

Many Modifiers have been significantly changed or completely replaced since the original 1.19 version. As the 1.19 version of the module was an experimental version there is no easy upgrade path to 1.20.

The Focused, Berserkers, Poised, Reckless, Guarding, Merchants armor and Deliberate, Light, Ascended weapon Modifiers were removed in the 1.20 update, replaced by Fluxed, Poisonous, Fractal, Archery, Totemic, Equestrian for armor and Giant and Chiming for weapons.
