Overgrown’s Apoli

Apoli is a mod for building custom powers, unique abilities, and entirely new game mechanics. All through data packs that are themed around modular design. It’s the engine behind Overgrown’s Origins.

To get started, create a power file under data/<namespace>/powers/ in your data pack.

The mod features:

• A power system with 100+ built-in ability types, grantable to any entity. Think of it as a toolkit for superpowers (No Java Required).
• A typed action system spanning entity, bi-entity, block, item, and meta actions.
• A comprehensive condition system across 7 context types.
• Data-driven skill trees for progression paths and unlockable abilities.
• A physics-based rope and grapple system (swing, leap, and reel).
• An entity disguise system for transforming mobs and players.
• Custom entities: projectiles, minions, and player clones.
• Data-driven keybindings, defined entirely through data packs.
• Custom recipes and loot functions that grant powers.
• A built-in expression engine for math-driven power values.
• Optional integration with Trinkets, Curios, Accessories, Figura, Icarus, and Hardcore Revival.
• Built for real servers: indexed power lookups, chunked network sync for large packs, and a versioned protocol that fails safely instead of desyncing.

Available for Fabric and NeoForge, on 1.20.1 and 1.21.1.
