Capabilities of Life Tap

[ak404]

OK, I'm perfectly aware that Life Tap imparts 50% life leech to whatever's cursed by it. Does this also work on enemies that'd normal be unleechable like skeletal mages, skeletons, and what not? What about PI undead being hit by a paladin with a Sanctuary aura up?

And (I really don't know this) does Conviction pierce physical immunity?

[adeyke]

Life tap works any time you deal physical damage. So it does work on unleechable monsters. Sanctuary allows Paladins to ignore physical resistance of undead, so with it, they can deal physical damage to PIs, so life tap would also work.

Conviction only lowers fire, lightning and cold resistance (and defense). It has no effect on physical, magic or poison resistance.

[Obi2Kenobi]

Only Amplify Damage (-100%) and Decrepify (-20%, I think, I suddenly forgot...) lower physical resistance.

[adeyke]

Decrepify does -50%.

Against PIs, amp does -20% and decrepify -10%.

...which means that a paladin can leech life with his smite skill with it.
