Guild Wars 2

I was just wondering about a crit-based life steal necromancer rather than the dozens upon dozens of MM or conditionmancers out there. Would life steal skills/sigils stack with each other?
Say you ran 4 superior vampirism runes/2 precision runes, and you had dagger/any offhand and axe/different offhand. You put Superior sigil of intelligence on the axe and Superior sigil of leeching on the dagger. Then most of your utilities here dont really matter except for Summon Blood fiend. Also, you might have omnomberry ghost for more lifesteal on critical hits.
What im wondering, is if you used Taste Of Death in combat and gained the lifesteal from Vampirism’s #4 effect, switched to axe, gaining the 100% crit chance then swapped back to Dagger for the Leeching sigil’s effect and used Life Siphon. Would all those effects stack up? or do certain sigils not work like that. Because the way I see it, you’d siphon health from dagger#2 (along with extra lifesteal from the sigil,) steal life from the food’s effect, and you’d gain health from your next attack after using a heal skill( taste of death/just summoning blood fiend.) That’s 4 sources that increase the total amount of life you stole (assuming that it all DOES infact, stack up) which might make the lifesteal at least twice as effective, if not, more. I didn’t even include trait bonuses either. this is just from armor and sigils. Anyone have any input on this????

the +50% crit chance on DS is only on DS, and in DS you dont get healed not even by lifesteal

Here’s what would happen using your given scenario:

1) Taste of Death would heal you for 3,960 (+ whatever you have in Healing Power).

2) You then attack and gain 975 health from Superior Rune of Vampirism’s #4 effect.

3) You swap to axe and gain a 100% critical chance on next attack from Superior Sigil of Intelligence.

4) You make an attack of some sort; either with your axe or a utility skill that causes direct damage.

5) This attack has a guaranteed crit due to #3 above. You then have a 33% chance to steal 341 health as a result of having eaten an Omnomberry Ghost. Ghosts do not automatically life steal on crit. First you must crit and then hope you process that 33% chance to life steal. So maybe you steal another 341 health.

6) You swap back to dagger, processing Superior Sigil of Leeching.

7) You use dagger #2 Life Siphon.

8) You heal for 847 health from Superior Sigil of Leeching and up to 1818 healing (+ 5% of healing power) from Life Siphon; assuming every pulse of Life Siphon hits your target.

9) All throughout your attacks, you also have the potential to process Omnomberry Ghost’s life stealing with each critical hit you land.

You will heal a guaranteed 5,782 health using the above sequence. You will very likely heal for even more when taking into account healing power bonuses, Life Siphon hitting your target, the potential to process Superior Rune of Vampirism’s #2 effect, the potential to process Omnomberry Ghosts a few times, and any life stealing traits you may have, as well.

Give it a try and let us know what your results are.
