Updated: Our apologies, but there is a slight revision to make regarding the illusionary items, as per our revised news announcement:
Armor of Illusion, Bow of Illusion, and Sword of Illusion have no safe enchant limit -- players run the risk of blowing up these items with the first attempt at enchanting.
Here are the special "Illusion" event items and their stats:


Illusions should be weightles
Illusions should be weightless seeing as they are illusions.
