enchantencore:lovely_aura
A purely cosmetic enchantment. While the helmet is worn, you are surrounded by hearts and pink dust. The aura reacts to what you do: it trails behind you while you walk, grows stronger while you stand still (also on armor stands wearing the helmet), bursts when you get hit, and is also applied to your tamed pets and to most projectiles you shoot. It has no gameplay effect.
This enchantment has an anvil cost multiplier of 1. When combining it from an enchanted book, the cost is halved.
