Mod Wiki
Thunderbound Mjolnir
Quickstart
Craft Mjolnir at a crafting table. The recipe unlocks once you have a mace:


Equip it in your main hand. In its starting Lightning Strike mode, aim at a block or creature and use Mjolnir to call down lightning.
To cycle modes, sneak and briefly use Mjolnir. On a controller, you can also click the right stick. The action bar shows your selected mode. Try Hammer Throw next: use Mjolnir and release to throw it; it returns to you.
Overview
Mjolnir is a combat item with four modes: Lightning Strike, Hammer Throw, Bifrost, and Hammer Flight. Holding it in your main hand also grants strength and bonus health. Its falling-hit attacks reward striking enemies during a descent.
What It Adds
- Mjolnir: A craftable hammer that provides combat abilities and holding bonuses.
- Four selectable modes: Lightning Strike, Hammer Throw, Bifrost, and Hammer Flight.
- Fall-powered attacks: Descending melee hits deal extra damage; a sufficiently long fall can trigger a shockwave.
How To Use
Modes cycle in this order: Lightning Strike → Hammer Throw → Bifrost → Hammer Flight → Lightning Strike. Sneak and briefly use the hammer, or click the right stick on a controller, to switch. Check the action bar to confirm the current mode.
- Lightning Strike: Aim at a block or creature and use Mjolnir. The strike uses Minecraft’s lightning effects, which can ignite nearby flammable blocks.
- Hammer Throw: Use and release to send Mjolnir forward. It can strike creatures on its way out and back, then returns to your inventory. If your inventory is full, free a slot so you can catch it.
- Bifrost: Aim at a block and use Mjolnir, then release to begin the cast. After a brief charge, you teleport to a safe spot near the block you targeted. You can also use
/thunderbound:bifrostwhile holding Mjolnir to teleport toward the block you’re aiming at. - Hammer Flight: Hold use to steady yourself, aim, and charge; release to launch in the direction you’re looking. A longer charge increases the launch’s reach, speed, and damage. If the hammer dives steeply into the ground, its impact creates an electric shockwave.
Crafting And Obtaining
Craft Mjolnir at a crafting table using the recipe above. You need a mace to unlock the recipe.
Abilities And Mechanics
- Holding bonuses: Strength and bonus health apply while Mjolnir is in your main hand.
- Falling melee hits: While holding Mjolnir, hit a creature during a fall to add damage based on your fall distance. The falling-hit charge is spent on that strike.
- Power slam: By default, a fall of at least 8 blocks triggers an extra hit and a shockwave that damages and knocks back nearby creatures. You can adjust fall-strike settings.
- Flight impact: In Hammer Flight mode, a steep downward hammer impact on the ground creates a separate shockwave.
Progression And Strategy
Start in Lightning Strike mode to hit a distant target, then switch to Hammer Throw for a moving attack. For a power slam, get above your target and land a melee hit while descending; save a longer fall for the stronger shockwave. In Hammer Flight mode, aim downward and release if you want the hammer to strike the ground.
Adjust personal combat and ability options with /thunderbound:mjolnir_settings, including strength and health bonuses, lightning range, fall-strike settings, and flight charge.
