a feature removed as a bug in pre-1.17 -> https://bugs-legacy.mojang.com/browse/MC-225190
Description
CONDITIONS: You do need any type of Sword and Enchant it With Knockback (any level) and by, the Tnt is thrown in the direction the player's hit is facing
ENCHANTMENT LEVELS: Each enchantment level increases x2 the current distance of the launch , the default distance is 6 (i think) and each level multiply x2 that distance
