Disenchantments

Ever wondered what it would be like if enchantments worked backwards? No? Too bad!
List of enchantments so far:
Bluntness: Lowers the damage of your weapon
Fire Absence: Grants fire resistance to attacked mob for 4 or 8 seconds depending on level
Decaying: Damages equipment when EXP is collected
Breaking: Adds a chance to take double damage each use
Blessing of Arthropods: Reduces damage dealt to arthropods and gives the arthropod Speed IV

Numbers are the same as the normal enchantments, but flipped!
