Environmental Spells

Each biome yields its own magical resources, and those materials are used to craft spell books. A recipe combines four resource blocks with one vanilla book, so exploring the world becomes the route to stronger magic. Spells differ by effect and power, and the mod includes five unique spell books with different strengths. Forest spells sit at the beginning of the progression, with roots that can entangle enemies, while the stronger books reach into legendary and ancient territory, such as a scream that devastates a Warden.

The Abyssal Tome is the rarest book in the set. Spell effects are limited to hostile mobs, so spells do not harm players or friendly creatures. Gameplay is balanced with cooldowns and durability costs on the books, which keeps each cast a deliberate choice. Nether-sourced items are fireproof and lava does not burn them, so they can be carried through those regions.

Environmental Spells runs on client and server, so the server and every player need it. The mod is published for Fabric only, in two game versions: 1.21 and 1.21.1, with 1.0.0 for 1.21.1 as the latest file. It is released under the MIT License, and the code is not open source. Fabric API is required.
