Need advice please. No green gems?

[scarletgamester]

Thank you for your advice, but I don't think I explained myself very well. The problem is I am not finding any green mind runes on the map, not on the ground, in chests or as rewards, plenty of red might and blue magic runes but no green mind runes.
I know i'm playing as a mage, but, I still need some mind runes to develop my skills, If the only mind runes I get is when I level up (which is only one or two) I won't be able to do that by the end of the game. I know things are set in place randomly at the start of a new game, maybe I've had a bad roll of the dice.

I don't mind a challenge but I still need something to work with,.
