i need a 10-12 eth throwing spear rare
I actually managed to imbue one on a level 8 and it got the brutal mod which i want. I'm not sure what level i should be imbueing at for best results thowever. The imbue handbook only really references level 9s and i think it says the character level that is imbueing should be level 22. What level would be best for imbuing for the brutal mod which requires level 10? Or how can i figure out what i need

Affix Atribute item lvl
Brutal 41-50% Enhanced Damage Weapons(14)

I think if lvl 9 best is 22, and you're trying for lvl 10-12 then I'd probably just do lvl 22-25 ish. But worst case it rolls up to lvl 12-13, can always go Angelics/CK boots
