+X% Magic Shield bonuses from the intellect stat do not interact with the Magical Life talent (Converts magic shield to health).
Talents that increase +X% Magic Shield DO work however. Meaning they increase magic shield which therefore increases health.

Also for whatever reason, "+% All Elemental Damage" talents aren't increasing spell damage (But The All Elemental Damage increase from the Elemental Purity talent still does) and, even more bizarrely, +% Elemental Resist talents INCREASE elemental/spell damage, more than twofold as well (12% increased resistance talent gives me a 30.1% increase in damage on my fireballs)
Tested across different nodes for each and stays consistent. Also worth noting element specific talents like +7% fire damage still work.

This might take me a while to fix. The elemental res boosting damage is so bizarre

managed to fix the magical life issue!

!!! Awesome!
