Applying the Loyalty enchantment to a cooking knife eliminates the need to walk over and retrieve thrown blades, while also unlocking a unique synergy with Farmer's Delight's Backstabbing enchantment.
Enchanting Knives with Loyalty
1. Obtain a knife from Farmer's Delight (or another compatible mod) and bring it to an Enchanting Table or Anvil.
2. Apply the Loyalty enchantment, and optionally pair it with Backstabbing for extra combat damage.
3. Throw the knife by holding and releasing Right-Click.
Once the blade strikes an enemy or lands on a block, Loyalty pulls it straight through the air back into the exact inventory or offhand slot you threw it from.
Setting Up Returning Backstab Strikes
Normally, triggering bonus damage carefully requires sneaking behind a target or using invisibility, but returning Loyalty knives bypass the invisibility requirement on the return trip:
1. Throw your Loyalty- and Backstabbing-enchanted knife past an enemy or into a block directly behind them.
2. Position yourself so the mob stands directly between you and the landed knife, facing toward you.
3. As the Loyalty enchantment pulls the blade back to your hand, it will strike the enemy from behind and deal the Backstabbing damage bonus automatically.
