How to Freeze Enemies and Light Up Your Surroundings
Freezing Enemies in Combat
Controlling hostile mobs during a fight gives you a major advantage. You can apply the Ice Aspect enchantment to swords up to level 2. Ice Aspect can be found as a guaranteed spawn inside ancient city ice box chests, as well as in trial chamber normal vaults.
At level 1, Ice Aspect gives your attacks a 10% chance to freeze enemies for 3 seconds. At level 2, that chance increases to 20%. When an enemy is frozen, they become completely immobile, though players are still able to move their camera and fight back. Note that Ice Aspect is incompatible with Fire Aspect and Web Snare.
Illuminating Dark Areas
While fighting in dark caves or night environments, visibility is key. You can apply the Luminosity enchantment to your chestplate up to level 3. Luminosity is available via the enchantment table, villager trades, and random loot.
Depending on the level you choose, Luminosity makes your character emit light directly into the surrounding environment. Level 1 emits a light level of 5, level 2 emits a light level of 10, and level 3 emits a full light level of 15, letting you navigate dark areas safely without constantly placing torches.
