This page lists all of the enchantments added in AbyssalCraft, with information on their usage.
Sword Enchantments[]
Coralium[]
The Coralium enchantment functions like the Fire Aspect enchantment. Upon hit, it applies the Coralium Plague (instead of setting the entity on fire).
Dread[]
The Dread enchantment works like the Coralium enchantment, except it applies the Dread Plague.
Light Pierce[]
The Light Pierce enchantment works like Smite/Bane of Arthropods, but is effective against Shadow Mobs (such as the Shadow Creature, Shadow Monster and Shadow Beast).
Armor Enchantments[]
Iron Wall[]
The Iron Wall enchantment is a "anti-knockback" enchantment; ie. it negates any knockback from enemy attacks.
Potion Effects (more explained):[]
Coralium Plague deals 1 heart of damage per second (at a rate between Poison and Wither).
Dread Plague deals 1/2 heart of damage per second, while also reduces your food bar (like the Hunger potion effect does, de-saturating it).
