About L2 Hostility

From Modrinth

Enemy enhancement mod that buffs enemy and adds special traits for them. Difficulty progression suits player strength well

Dependency: Curios API, Patchouli, L2 Library, L2 Complements (to utilize some enchantments and effects)

Suggest to play with: L2 Weaponry, L2 Archery

This mod adds a difficulty system that makes mobs stronger, and have special abilities.

This mod is similar to Champions, Scaling Health, and AtomicStryker's Infernal Mobs but differs in the following ways:

  • Mob strength progress with player. Player would not encounter absurdly strong mobs at the beginning
  • Mob strength are dependent on a lot of factors, instead of just being randomly strong.
  • Reasonable progression: Increase difficulty only when you kill strong enemies. Decrease difficulty when you die.
  • Traits, Difficulty, and Drops are highly customizable through config and datapack.
  • There is a mechanic to make a region safe. You don't need to worry about strong mobs around your vase forever

It also adds 28 curio items to make you stronger and 2 enchantments to help fighting the mobs.

In-game Progression:

  • Kill mobs with traits to collect ingredients
  • Craft Curse of Envy to enable you to get trait symbols
  • Get trait symbols and use them to craft better gears
Detailed Mechanics

There is a level associated with all enemies. Level is determined by the dimension, biome, position, nearby player difficulty, and entity type. As the level becomes higher, mobs have higher health and deal higher damage, and higher chance to have strong traits.

There is a difficulty level assigned to chunk sections and players. Killing mobs to gain chunk and player difficulty, and die to lose player difficulty. Use Hostility Detector to know about current difficulty, use Hostility Orb to make a chunk section permanently not spawning mobs with level.
