Enhancement Booster Salvage

Overview

Enhancement Boosters are Special Salvage available from the Reward Merit Vendor, Auction House, or as occasional drops. When applied to Invention Origin Enhancements (IOs), whether it is a set piece or a common piece, it increases the effectiveness of the enhancement by 5% per application, without changing the base level of the enhancement. IOs can be boosted by a maximum of 25%, or Level X+5.

Using Boosters

To use this salvage, enter the enhancement management screen. Click on the power that contains the slotted IO. Once in the combine screen, click on the enhancement to boost. This will cause the enhancement to slide into the left combine slot and will cause the Enhancement Booster salvage to appear in this screen. Click the Enhancement Booster to cause it to slide into the right combine slot. Click Combine to complete.

Procs and Globals are unaffected; however if they come with an enhancement portion, the enhancement portion is boosted (for example, with the LotG: Def/+Rech, the defense is boosted but the recharge bonus is not).

As an example, a level 30 Damage IO buffs damage by 34.8%. Boosting it with one Enhancement Booster brings it to 36.54% enhancement, which is just under a level 35 in enhancement value, while still allowing a level 27 character to slot it. Boosting it with five Enhancement Boosters brings it up to 43.5%, which is higher than a level 50 Damage IO, and still allows a level 27 character to slot it!

Due to the percentage multiplier, the higher level an IO is, the bigger the boost becomes; a level 50 Schedule A IO with five boosts goes from 42.4% to 53%!

Boosted enhancements function at their natural level; exemplaring does not break bonuses until exemplared more than three levels below the natural level of the IO, like normal. This means a build with a lot of Level 30 set enhancements that have been boosted can perform on par with or above Level 50 sets, and set bonuses will still function all the way down to level 27. However, the exemplar effect on enhancements still applies, if each individual enhancement portion is large enough.

Enhancement Diversification affects the total boosted values.

Boost Values

The following table shows the percentage multiple boosters grant, and by what multiplier an IO will be modified by, followed by specific enhancement examples.

On Attunement

Attuned enhancements (such as Archetype Enhancements or Store-Bought Enhancements) cannot be boosted and vice versa. To attune an enhancement, the boosted enhancement must be unslotted (or replaced at a loss) with a fresh copy that can be catalyzed.

Historical

This section contains information about changes that took place in City of Heroes/Villains. It is provided for historical purposes.

Prior to Issue 25, Boosted enhancements could not be traded to other characters. Attempting to do so directly would remove all Boosts, and all indirect trade methods were blocked by the game client.
