Enhancement Diversification

Overview

Enhancement Diversification, usually abbreviated ED, is a system of modifying the effects of enhancements when the total enhancement is above a certain percentage. Enhancement Diversification became effective on the production servers as of the release of Issue 6 and City of Villains.

Enhancement Diversification is based on a system of dimishing returns on enhancements slotted to raise bonuses to a very high level. It primarily affects Single-Origin Enhancements and Hamidon Enhancements, though it is possible that enough slotted Dual-Origin Enhancements may be affected as well.

Due to the diminishing returns of multiple enhancements of the same type, it is clearly inefficient to put more than three Single Origin enhancements of a given type in one power. For instance, three damage Single Origin enhancements will give you "the most bang for your buck." Note that Single Origin enhancements of another type will not experience the diminishing returns from the other enhancements. Example: If you put three damage enhancements into one power, and put an accuracy enhancement in the fourth slot, the accuracy would not be reduced to 4.99% because of the damage enhancements. The reduction only applies to enhancements of the same type.

What Enhancement Types are what bonuses (schedules)? The percentages in parentheses represent Single, Dual, and Training Origin enhancements, respectively. The numbers also assume that the enhancement is equal to your own level. An enhancement that is one or two levels greater than your level will work a little better; one or two levels lower than yours will provide a little less than these percentages.

Schedule A Enhancements (33.33%, 16.66%, 8.35%) are:

Accuracy, Confuse, Damage, Defense DeBuff, Drain Endurance, Endurance Discount, Fear, Fly, Heal, Hold, Immobilize, Intangible, Jump, Recharge, Recovery, Run, Sleep, Snare, Stun, Taunt, To Hit Debuff

These bonus types will see a 10% reductions when the bonus is 70% or more, a 30% reductions at a 90% bonus, and a 85% reductions at a 100% bonus or greater. Specifically, if you put six even-level Single Origin enhancements in one power, they will enhance the power to the following degree: 33.33%, 33.33%, 28.33%, 4.99%, 4.99%, 4.99%.

Schedule B Enhancements (20%, 10%, 5%) are:
