lvl 70 - dying too fast - help please!

if you gonna go blood magic again. i got some useful info for ya. ( feel frre to correct me if i'm wrong ^^')

with blood magic and malee type char, you prolly want to use life leech or life on hit.

The maximum you can have hp regen per second is 20% of max HP (if i recall), however, quality life leech gem will increase the max % u can regen per second.
So if you have 3k HP you will regen 600 HP/sec at max.

life leech gem is count as hp regen, but life on hit is not a regen.

i have a tip, high level it can be good to drop blood magic to get the % aura's, then use a BM gem on your skill and you'll be back were u started(should be your 5-6 link), this actually increases both offence and defense and with the aura reduction in tree you can get 4 40% aura's(w/ mana reduction gem 20q)

well you are 70 so im guessing you have finished act 3 merc in which case your hp is fine, grind docks til 75 then start doing maps, you still got 5 easymode lvls left that you can cheese thru in a group, no reason to get more hp like the other posters say, but dont expect to solo maps without better gear.

I would much rather run a talent tree close to this

it will give you alot of hp to survive merciless

but its not all about spec make sure you upgrade your gear and have +health on basicly all the pices

You're in duelist tree, so with the upcoming patch, you should be getting a full respec. Should be nice.

Seriously? So I dont need to reroll? xD I just started and lvl 28 lol xD

Regarding the tree, why go for Body and Soul over going north like Grekenfailed is proposing?

Thank you everyone who helped!
While I started rerolling (lvl 28 by the time the patch arrived) I got a full free respec.

With the respec I have now 2769 HP along with 3884 armor. I've lost roughly 200ish dps but I've gained a lot of survivability! I'm going to keep playing this one and see how it goes!

Again thanks alot!
