Addon: Neo Elementals | Survival Overhaul
Author: TheeKG
Neo Elementals is a difficulty and progression overhaul for Bedrock 1.26 and newer. Nine redesigned encounters control access to major stages of the game, preventing players from rushing directly to the strongest resources.

Ordinary monsters receive more capable behavior: Creepers time explosions more precisely, Skeletons aim better, Witches support nearby mobs and Endermen can warp close targets. The first three progression bosses unlock the Nether and deepslate regions. Nights cannot always be skipped, and early fog limits visibility.

Seven optional Elemental Nymphs-Water, Sand, Ice, Lava, Storm, Forest and Void-use individual moves and drop specialized gear. Together with progression enemies, the add-on contains eight minibosses and more than twenty new mobs.
Difficulty is paired with recovery tools. Death creates a beacon and keeps equipment together; allies can return a player to the location, while a revised Recovery Compass offers a costly solo teleport. Heart gems can double maximum health, and late-game Immortal Netherite gear is unbreakable and retained after death.

The in-game progression item contains guidance, settings and an item finder. No experiments or player.json replacement are required.
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.
