The Illusion equipments can be enchanted by using Modification Modules, given by Rebellion (sp_cor 108, 130).
You can exchange 30 Unknown Parts (25669) and 5 Cor Core (25723) for a random Modification Module.
To apply the Modification Modules, equip the Illusion armor and then speak with RS26 (sp_cor 106, 136). The enchanting process consumes the Modification Module and never fails.
Every Illusion equipment can receive up to 3 modifications, but each Module type can only be applied a certain number of times, depending of the equipment piece.
For Legendary Enchants however, only one can be socketed at any given time, even if they're not the same.
The following table lists the available modules, their effects and their enchantment limitations.
