Spellsteel is a NeoForge mod for Minecraft 1.21.1 that adds 21 custom enchantments, each with 3 levels that scale in power.
It covers mining (Vein Miner, Auto Smelt, Reach), woodcutting and farming (Timber, Replant, Crop Circle), combat (Lifesteal, Backstab, Heavy Strike, Venom, Dash, Swift Strike), ranged (Explosive Arrows), armor and mobility (Magnetic, Night Sight, Deep Breath, Reflect, Cushioned, Spring, Swift Legs), and utility (Experience Boost).
You can get enchants from the enchanting table, anvil, /enchant, or the mod’s creative tab (every enchant at levels I–III). You can also find them in the world: 1 in 20 mob kills and chest opens can drop a common enchant book, and 1 in 1,000 can drop a rare one (Dash, Vein Miner, Explosive Arrows, Lifesteal, Backstab, Reflect, Venom, Auto Smelt, Timber).
Standout features include Dash (right-click with a sword to lunge forward), Vein Miner for ore veins, and Magnetic to pull nearby drops toward you.
