A talent in Darkness tier 2 15% doesn't seem to help look: Dark Charge Charges your lightsaber with dark energy, giving your attacks a 50% chance to drain life force from the target, dealing 179 internal damage and healing you for 130. This effect cannot occur more than once every 1.5 seconds. Increases your armor rating by 150%, shield chance by 15% and threat generation by 50%. While active, melee bonus damage is reduced by 5%. Requires a double-bladed lightsaber. Does not break Stealth. And Swelling Shadows Increases the chance your Dark Charge applies its effects by 15%. If you spec into Swelling dark charge will give your attacks 65% chance to drain life force from the target. It doesn't help at all because DC effects is on a 1.5 CD. Either ways the effect will proc, an extra 15% doesn't make to much of a difference... I could be wrong but that's why I posted
