"secondary" Rune investment
 

Hi
As a mage my main runes are the magic ones. I also have shitloads of might/mind runes.

my question is: As a mage what should i invest my "secondary" runes in.
for example ive found out that reserve in the mind tree is excellent.

what have u invested your secondary runes in?

I usually invest up to reserve in the mind tree too then I focus on getting Onslaught in the might tree. Its very expensive but definitely worth it because your troops can act faster and weaken the enemy before they attack you on first turn (especially useful against black dragon, necromancer and other dragons as they have high initiative and speed).
You can also invest further in the mind tree (tolerance) instead if you're a fan of undead (vampires, cursed ghost, skeleton archer) and don't want them to clash with your other troops.

that you for your help, il check in to the onslaught skill

Best
