Corrupt Charge

Corrupt Charge increases the Channeling damage of melee weapons while reducing Channeling efficiency.

Stats

Rank	Channeling Damage	Channeling Efficiency	Cost
0	+25%	-10%	4
1	+50%	-20%	5
2	+75%	-30%	6
3	+100%	-40%	7

Channeling increases most weapon's melee damage by +50%. Corrupt Charge increases Channeling's damage based off this value, thus at max rank it increases Channeled melee damage to +100%.
- This can be combined with Killing Blow for +220% Channeling damage, or a total damage increase of +160% while Channeling.
A -40% decrease in Channeling Efficiency translates to an additional 2 Energy per hit while channeling. Without Channeling Efficiency mods, using Corrupt Charge increases Channeling cost to 7 Energy per hit.

When this mod was released, only a fully ranked version could be acquired. It was patched in Hotfix 10.3.1 (2013-10-09).
As of Update 13.0 (2014-04-09), this is the only Corrupted mod that does not feature any sort of Prime equipment on its portrait.
- Prior to Update 13, the mod depicted a Frost Prime brandishing Fang Prime.
Due to a bug introduced around Update 13.0 (2014-04-09), Corrupt Charge could be obtained through Transmutation up until late 2014. This made it one of two Corrupted Mods that could (unintentionally) be obtained outside of Orokin Vaults (a similar bug occurred with Anemic Agility, which was a potential drop from Ballista from Update 13.0 (2014-04-09) to Hotfix 15.7.2 (2014-12-19)).
Unlike most mods, the picture shows an Excalibur wearing the Pendragon helmet, his Immortal Skin, as well as a different color scheme. This is a rare instance of a mod depicting a non-default character loadout. The other examples are Life Strike, Second Wind, True Punishment, Enduring Strike, Warrior's Grip and Quickening, all of which are channeling mods.
