SK Life Leech/Drain Health, dark attribute?

Are these attacks enhanced by dark attribute weapons?

yeah those are all dark attacks so if someone has dark rest it lessens the damge if someone has dark votra it do alot more that why if u ever do it to a angel it do alot of damge ALOT of damge

L2P does not have Life Leech & Drain Health listed as Dark attacks. So I'm a little dubious. Are you a SK with a dark weapon by chance?

they are dark atribute, I tested it with a friend of mine ..... when i used surrender to dark he gave more damage.
plus all the drains in the game are dark since C5 or T0(interlude)

alltogether i can honestly say the SK drains are almost useless skills anyways... they need to amp the damage a little more or at least make it 100% damage return as hp...

Life leech gives 100% dmg back, Life drain gives 20% but has greater power, vampiric cubic gives 40% back. All these are considered dark attacks. You will notice the difference clearly in catas, if you drain an Angel and then a Demon that have basically the same mdef. Angel is getting nuked by a drain. I have one shoted an angel in catas with mcrit of drain health.
