Liche invincimonk?

Aura of the liche gives what, 1/2 max hp and 1/2 damage taken. This is a skill MADE for near-invincimonking. If you use armor-switching well, you easily can get to the 50s, I think.

Let's see.
1/2 of 450 is 225 -75 -75 = 75
So you just need 2 sups to get down to a good range (i THINK, haven't tested quite yet), and my character is a necro, so that reduces the cost of making this build by quite a bit. the problem is that it's a death skill, unlike the skills you might use for farming.

So, plenty of blood magic, enough death to roll over aura to a decent amount of time, and enough prot to keep bond from completely neutering me. Wait, no, Maybe I'll try using prot spirit and throw on a major, bringing life to 25...

Aura of the liche
Dark aura
blood renewal
touch of agony
barbed signet
plague touch
prot spirit
healing breeze (maybe... getting it to 5 regen aint hard, and thats all i need)

So, would this work? I'll try it soon and get back to ya.

EDIT: Nope. dark aura's life loss skipped over the prot limit, killing me quickly.
