Personally I max it before I put points into the other auxiliary skills. I I’m not short on points then it stays but I take away some from it if I need it on the others.
A tiny tweak: if you swap one of the Spellscorched to the belt, you’ll gain a small amount of armor for every slot.
nice catch! 
Thanks for the tip! Doesn’t add much more armor though, but still a nice touch 
Nice build, added to my thread. 
Glad to see after my double blitz commando another blitz build.
