Addon: Echo Dungeons
Author: EchoForge

Enemies and bosses
Familiar hostile mobs are joined by mini-bosses and major bosses with distinct attacks. Encounters are designed around learning patterns rather than fighting stronger copies of vanilla creatures.

Weapons and armor
Dozens of melee weapons, five ranged weapon types, many armor sets and artifacts create a wide choice of builds. Equipment changes how the player approaches groups, elites and bosses.

Progression
Powerful enemies become the main source of valuable loot, encouraging repeated exploration and increasingly difficult battles.
How to install the add-on
Download the .mcaddon or .mcpack file, open it with Minecraft and wait for the import to finish. Then enable the resource and behavior packs in the world settings. If the add-on requires experiments, turn them on before launching the world.
