LA ermor pretender question

[NTJedi]

2 in all paths? I would drop blood from 2 down to 1... then use the extra points elsewhere.

I would take 4 earth for the following reasons:

Sacred shroud armor will reinvigorate your mages.
Access to casting useful globals such as earth blood deep well, mechanical militia and forge of the ancients.
Access to summoning the earth kings, one which generates earth gems.
Great battle spells unaccessible or made stronger such as blade wind, petrify, marble warriors, and army of gold.
