The Pinnacle of Arthritis - Blood Mage Bone Cage Build

Synopsis
Ultimately this build boils down to many jagged pointy objects protruding into your enemies as opposed to yourself, though a little bit on yourself.

It provides a great deal of defensive benefit from applying pin, periodically, and consistently, stopping all pursuers in their place while you unleash wave after wave of your calcium catastrophe upon them.

Lifetap for Cast on Critical is crucial, as you do not want to run out of all mana the moment you cast on a boss, unless you have high mana regen, but who wants that? You're a blood mage after all, who needs mana when you have excess blood loss to achieve.

This leads me to the most important part of the build.
Blood Mage is crucial for this build, so instead of focusing passives on max mana or mana regen, or all that silliness, you can instead focus on critical hit chance and critical damage and spell damage.
And probably a bit of energy shield and evasion rating, but that's assuming your enemies have not been made into deceased pin cushions long before you could concern yourself with the damage you may or may not have taken.

Turning mobs into pincushions, I like it :)

I would just selfcast corpse explo. I mean i play the same build ;)
Its pretty useful for mass cleaing abyss and breaches etc.

but this would make it a 3 button class, so thats not for everyone.
but corpse explo - magnitude - spell echo - zenith - considered casting/bleed is is wacky.

I tried some corpse explode earlier in the build, I liked it because it was chaotic, but I wanted to stick with the theme of bones and phys damage.
