Holding mastery over 14 spells is quite impressive when comapared to the populus indeed. However, it is not guarantee membership in the Tower. I myself had nearly 20 before I got in, and now, I am in the high 30's. I will say though, that before the departure of our leaders Khalan and Elendiel, he along with Caralee were the top prospects that we were looking at. Now that Caralee is among the Sages, perhaps Pug's time will come soon, if he continues to be dedicated to his cause.
