You can reinforce your equipment to increase its strength if you are dissatisfied with the current power of your equipment. The maximum level you can reinforce all of your equipment to is +16.
Players have to go to visit an NPC named: Domi from the City of Heroes (19;-49) and click on Equipment Reinforcement. He will ask you to place the equipment you want to reinforce and to put it in Reinforced Sapphires into the Reinforcement Interface.
You can place 4 Reinforced Sapphires into the reinforcement interface to increase your success percentage. You may click [Yes] to confirm, when you are happy with the percentage and you want to try your luck.
1) SUCCESS: Your equipment will level up by one reinforcement level which will increase the general strength and basic attributes of your item if your Equipment Reinforcement succeeds.
2) FAILURE: The current reinforcement level of this item will be decreased by one level if the Equipment Reinforcement fails.
There is also the risk of your equipment disappearing. Your equipment will never disappear if you use an item called [Stone of Guard] and if your equipment reinforcement level is already +6.
3) + 3 reinforced equipment will never be lower than + 3 if the reinforcement fails.
4) + 6 reinforced equipment will never be lower than + 6 if the reinforcement fails.
5) + 9 reinforced equipment will never be lower than + 9 if the reinforcement fails.
6) + 12 reinforced equipment will never be lower than + 12 if the reinforcement fails.
7) + 15 reinforced equipment will never be lower than + 15 if the reinforcement fails.
The system will automatically give blessing affects to your basic attributes once you have 10 items equipped with Reinforced Level +6, +9, +12, +15.
You can check your blessing effects from the Character Interface (Press Shortcut key ---C) when your Blessing Attributes are activated.
