CrossArms

CrossArms is a datapack that expands the crossbow into a full weapon platform.
It adds new enchantments, reworks Multishot, introduces advanced projectile mechanics, and allows crossbows to function as automatic weapons, shotguns, high-velocity rifles, and explosive launchers.

Some enchantments are intentionally incompatible to prevent extreme stacking and to preserve distinct weapon roles.

New Enchantments

Capacity (I–IV)

Allows a crossbow to store multiple arrows per charge, turning it into a multi-round weapon.

Increases maximum loaded arrows to 4 / 8 / 12 / 16
Removes the need to reload after every shot
Works only with regular arrows; other projectiles charge normally
Increases crossbow charge time
Incompatible with: Multishot, Acceleration, Bombard, Frenzy

Acceleration (I–V)

Greatly increases projectile speed, effectively turning the crossbow into a high-velocity weapon.

Increases projectile speed by 2× / 3× / 4× / 5× / 6×
Faster projectiles fly farther and deal more damage
Incompatible with: Quick Charge, Capacity, Bombard, Frenzy

Zero Drop

Disables projectile gravity while sufficient velocity is maintained.

Greatly improves vertical accuracy
Disables critical hits
Incompatible with: Piercing, Bombard, Multishot

Ricochet (I–IV)

Allows arrows to bounce off blocks.

Each level grants +1 additional bounce
Bounces will not occur if projectile speed is too low
Each bounce reduces arrow speed
Incompatible with: Piercing, Bombard, Deflector

Deflector

Turns arrows into projectile reflectors.

Fired arrows can reflect other projectiles
Reflected projectiles copy the Deflector arrow’s speed and direction
Cannot reflect other Deflector arrows
Compatible with Acceleration
Incompatible with: Piercing, Quick Charge, Ricochet, Bombard, Frenzy

Recycling (I–III)

Allows partial recovery of ammunition after hitting a target.

25% / 50% / 75% chance to return the arrow to the shooter
Works only with regular arrows
Incompatible with: Multishot

Bombard

Converts the crossbow into a true explosive weapon.

Direct hits cause immediate explosions
Explosions destroy blocks similarly to TNT
Hitting a block spawns ignited TNT that explodes after 1 second
Each shot consumes 15 durability instead of 1
Increases crossbow charge time
Incompatible with: Multishot, Piercing, Capacity, Acceleration, Zero Drop, Ricochet, Deflector, Frenzy

Frenzy

Turns the crossbow into a minigun-like weapon.

Automatically feeds normal arrows from the inventory
Introduces a heat mechanic
Auto-loading stops when the crossbow reaches 1 durability
Once at 1 durability, the crossbow cannot be manually loaded
Designed for sustained fire by holding right-click
Incompatible with: Multishot, Piercing, Quick Charge, Capacity, Acceleration, Deflector, Bombard

Heat:
Heat is applied to the player, not the weapon, and persists even if the weapon is dropped.

Shooting with Frenzy increases heat
Heat gradually decreases over time
Higher heat increases Frenzy damage
At minimal heat, Frenzy damage is reduced

Heat thresholds:

Level 3 (red): Player begins taking fire damage (can be prevented with Fire Resistance)
Level 5 (black): Continuing to fire will break the crossbow (down to 2 durability, allowing one final shot before becoming unusable until repaired)

Level 3 and Level 5 transitions are signaled on shot, allowing time to stop firing.

Changed

Multishot

Reworked to further embrace its shotgun role.

Now has 3 levels instead of 1
Each level adds 2 additional projectiles (7 at level III)
Horizontal spread increases with each level
At level I, the spread is lower than in vanilla
Added Neighboring Bonus to fired arrows
Incompatible with: Capacity, Recycling, Bombard, Zero Drop, Frenzy

Neighboring Bonus:
When multiple Multishot projectiles are close to each other, they increase each other’s damage.
This significantly boosts short-range effectiveness.
Only one arrow can register a true hit, while others may bounce off, penetrate, or be removed.
Effective range is roughly 3 blocks and may vary due to natural spread.
