True Punishment

While Channeling is active, the True Punishment mod increases your Critical hit chance but decreases Channeling efficiency.

Trivia

 * 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, Enduring Strike , Warrior's Grip, Quickening and Corrupt Charge, all of which are channeling mods.
