City of Heroes Enhancement Guide
This guide assumes you understand the basics of Enhancements - if you have more general questions, check out this highly detailed Guide on the Official Forums.
General Mechanics
The Principal Rule of Enhancements: Single Origins are always better than Dual Origins, which are always better than generic training enhancements.
Base SO Percentage at equal level are either 20% or 33.33%
Base DO Percentage at equal level are either 10% or 16.67%
Base Generic Percentage at equal level are either 5% or 8.33%
Range/Cone Range, Damage Resistance, and Defense Buff use the lower value (5/10/20). All other enhancements use the higher value.
You get diminishing returns for each enhancement of the same type you put in a particular power. For example, take a series of endurance reductions with a base cost of 100:
Net Endurance Cost = Base Endurance Cost / (1 + (Sum of Enhancements slotted))
1 SO Slotted: 100 / (1 + .33) = 75
2 SO Slotted: 100 / (1 + (.33 + .33)) = 60
3 SO Slotted: 100 / (1 + (.33 + .33 + .33)) = 50
4 SO Slotted: 100 / (1 + 1.33) = 43
5 SO Slotted: 100 / (1 + 1.66) = 38
6 SO Slotted: 100 / (1 + 2) = 33
For 'add' enhancements, such as accuracy, the example runs as follows:
Chance to Hit = Base Chance * (1 + (Sum of Enhancement Percentages))
[The Base Chance to hit a 'white' foe is 75%]
Combining Enhancements
You can combine enhancements of the same type (or of the same effect, with Dual Origins) to create a higher level enhancement. If successful, the final enhancement will be one level over the higher of the two combined enhancements. If unsuccessful, only the higher of the two enhancements will be kept. A 20++ enhancement is identical to a 22 enhancement.
+3 = *1.15
+2 = *1.10
+1 = *1.05
0 = *1.00
-1 = *.90
-2 = *.80
-3 = *.70
So, for example, if you're level 15, and you have a 15++ generic damage training enhancement, the modifier to your damage is 8.33 * 1.10 = 9.1%.
Type 1 (most) Enhancers:
| Level Diff | -4 | -3 | -2 | -1 | 0 | 1 | 2 | 3 |
| Training | 0.00% | 5.81% | 6.64% | 7.47% | 8.30% | 8.72% | 9.13% | 9.55% |
| Dual Origin | 0.00% | 11.69% | 13.36% | 15.03% | 16.70% | 17.54% | 18.37% | 19.21% |
| Single Origin | 0.00% | 23.31% | 26.64% | 29.97% | 33.30% | 34.97% | 36.63% | 38.30% |
Type 2 (Defense & Range) Enhancers:
| Level Diff | -4 | -3 | -2 | -1 | 0 | 1 | 2 | 3 |
| Training | 0.00% | 3.50% | 4.00% | 4.50% | 5.00% | 5.25% | 5.50% | 5.75% |
| Dual Origin | 0.00% | 7.00% | 8.00% | 9.00% | 10.00% | 10.50% | 11.00% | 11.50% |
| Single Origin | 0.00% | 14.00% | 16.00% | 18.00% | 20.00% | 21.00% | 22.00% | 23.00% |
Balancing Damage vs. Accuracy
You cannot reduce your chance to miss below 5%, so the general consensus is that the best bang for the buck is a 2:1 ratio of damage to accuracy.
With a base 100 damage:
6 DO Dam Power - 20 attacks, 15 hit, 200 damage, total = 15x200 = 3000
4 DO Dam/2 DO Acc Power - 20 attacks, 19 hit, 167 damage, total = 3173
