Vitality build is the best for survive only. With this
build we can't use Occult Ice, so our lock become very
poor, but we can use more interesting and powerful
skills (Faith for example) that can help us to stay
alive longer. Also with high Vitality and Magic we can
use more skill at a time and more often.
This build is more effective in large scale PvP or if
you need to stay alive (pulling catapult for example)
but almost useless in little PvP and PvE.
I suggest to use a Zeal because it has the lower
points on Dexterity that is the stat we don't need.
Strength: 5 or 25 or 50
(just for Solid Shield, depend only on how much your are
tanky, more tank less Strength need)
Tree of Protection
Heart of Steel or another Element
