Elemental Harmony

 Overview

The world itself becomes your power source. Elemental Harmony adds a living attunement system: where you stand decides what you become. Swim, burn, climb or delve, and each element charges up. Fill one to 100 and unleash a 30-second Elemental Surge.

100% vanilla data pack. No mods, no resource pack, no dependencies.

The Four Elements

Tide – charges in water or open-sky rain. Surge: Water Breathing, Dolphin’s Grace, Conduit Power.

Ember – charges when you are on fire, in the Nether, or standing in fire, lava or campfires. Surge: Fire Resistance, Strength, and undead within 5 blocks are set ablaze.

Gale – charges at Y 100 and above with sky access. Surge: Slow Falling, Jump Boost III, Speed II.

Stone – charges deep underground (Y 0 or lower), out of water. Surge: Resistance II, Haste II, Night Vision.

Charge gains 5 per second in the right place, and other elements slowly drain. Plan your route: a mountaintop storm charges Gale, a rainy coast charges Tide.

The Harmony Charm

Craft it shapeless: Echo Shard + Heart of the Sea + Blaze Powder + Feather + Amethyst Shard. Hold it in your off-hand to double charge speed and show a live charge readout on your action bar. You can also use /function harmony:give_charm.
