This is a new system being implemented into City of Villains and City of Heroes (when City of Villains launches) to promote the use of more different types of Enhancements in powers. Using a system of diminishing returns, when slotting the same type of Enhancement into a power, you will begin to see less effect of that Enhancement when the bonus reaches a certain threshold. The effectiveness of Enhancements you are slotting in can now be seen in the Enhancement Slotting screen.

What does this mean? Simply, if you are slotting Enhancements and your bonus to a single attribute reaches 70% through Enhancements, you will begin to see a drop in the amount each Enhancement should be giving you. If you exceed 100% bonus, then the drop will be more severe. We have added to the Enhancement Slotting screen a display of how much bonus you are getting from your Enhancements. When you are adding in Enhancements that will be reduced in effectiveness you will be able to tell.
