City of Heroes/Enhancements

Types of Enhancements

There are five known types of enhancements in City of Heroes: Training Enhancements (TO), Dual Origin Enhancements (DO), Single Origin Enhancements (SO), Trial Reward Enhancements (TR), and Hamidon Enhancements (HO).

Enhancements are broken down into two categories. Range, cone range, defense and damage resist enhancements use the lower of the two numbers in the following table; all other enhancements use the higher number.

Value of Enhancements

Training Enhancements:	8.25%/5%
Dual Origin Enhancements:	16.5%/10%
Single Origin Enhancements:	33%/20%
Trial Reward Enhancements:	25%/15% (affects multiple aspects of a power)
Hamidon Enhancements:	33%/20% (affects multiple aspects of a power)

Effect of Level

The level of the enhancement does not directly affect the benefit that enhancement. However, the level of the enhancement relative to the level of the hero does. An enhancement that is one level higher than the hero using it has a +10% bonus to the enhancement's base bonus. A level below is -10%. This works up to three levels. Example: a level 35 enhancement used by a level 32 hero has a 42.9% bonus. $TotalBonus=EnhancementBonus*1+((EnhancementLevel-HeroLevel)*10\%)$

When calculating the strenght of a power when it's enhanced, use the following formula for damage, defense, resistance, buff, or debuff type powers

$PowerStrength=BaseStrength*(1+(TotalBonus*NumberOfEnhancements))$

When calculating for a recharge, interruption reduction, or other similar power, use:

$RechargeTime=BaseRechargeTime\ (1+(TotalBonus*NumberOfEnhancements))$

These formulas basically mean every recharge reduction SO slotted in a power reduces the power's recharge time by 25%.
