Update Guide

Slot Enchant System


The Slot Enchant system is a new system in RO that allows players to add new slots to existing gears. While only certain gears can be upgraded, a variety of new items are available only through the use of this system.

When slotting an item, the item cost and success rate varies based on the type and aproximate rank of the item and you wish to upgrade. The equipment you are upgrading is completely destroyed and you are made a new one in its place should you succeed. This means that any upgrades, cards, or other modifiers applied to the original equipment will be lost durring the enchantment. If the upgrade fails, the items and zeny are completely lost.

Only certain gears can be upgraded, and some items will show different properties than the items you were initially slotting. The full list of slottable items and changes are listed further on.

The following chart represents the success rates of slot enchant based on the rank of the item you are enchanting.

C Rank:25% Success
B Rank:20% Success
A Rank:15% Success
S Rank:10% Success
