I bow before you my friend. I don't think I would have kept playing a Mage had I not invested in the sigils. The fact that you're a high level Mage is a testament to your determination.I have 20 sigils? Ish, lol.
I have friends ask me if they would like the game and I tell them all to give it a go, but don't play a Mage unless you're willing to use real money to get sigils or spend several minutes between mobs to regain energy.
