LIFE STEAL IS A LIE! Doesnt work the way you think

So ive been using Andarials Visage on my rogue
I immediately dropped the vampiric ability that adds hp per skill cast, as well as aspect of crowded sage
I figured i wouldnt need any other healing
Boy was I wrong
I started up a tier 100 to test this baby out. To my surprise i couldnt heal through damage even though i was literally doing millions of damage

Ive been comparing the healing, its VERY similar to the vampire healing ability
Feels almost identical

Life steal doesnt work the way you think it does…. The way every single game that has life steal works
Its not scaling with your damage. It appears to just be giving 3% of your hp pool per hit with the main difference being that the enemy is getting his life reduced

What i have found hilarious is that the healing is INFERIOR to “aspect of stolen vigor” that can heal well over 1.6k life per second (2.5k on neck)
Which i cant even use right now because andarials is taking over the slot

In fact defensively i would he better off with a helm with defensive stats that i could put my own life restoring aspect on.

The only reason i even keep using this item is because attack power + the poison aspect my possibly be scaling/have interaction with Xfals but i need target dummy to prove this

Considering putting this back in my bank

THIS ITEM IS NOT UBER

Im getting sick of these fake uber items
There are 3 ubers in the game as far as im concerned
Shako and the two swords

Could it be going off of base damage only?

I don’t have andarials, but I did take that power on my sever necro. I’m constantly corpse exploding, sever, and reap. I never have to use a potion. It might be class or class mechanics. However, I’m not 100 yet and haven’t run that high this season. So I might be wrong.

I tested mine at one of those vampire well things. Thinking with the vamp power plus this I could stand there and have loot raining on me. But unfortunately I couldn’t tell the difference between wearing it and not wearing it. Threw it back in the stash…

It’s probably something stupid like based on your base health.

didnt play rogue yet so i dont know their dmg structure, however from what i know it only applies to physical dmg components, not elemental dmg types. (which makes sense)
