Swift Sneak

Swift Sneak is a non-renewable enchantment that can be applied to leggings and allows the player to walk more quickly while sneaking.

Loot chest
Swift Sneak can be obtained only from loot chests in ancient cities. The chests can contain enchanted books with any level of Swift Sneak.

Speed
Swift Sneak increases the player's speed while crouching by 15% per level. At Swift Sneak level 3, the player's crouch speed equals 75% of their normal walking speed. Swift Sneak 4 and 5 can further improve crouching speed, but the crouching speed can never be faster than the player's walking speed.
