Okay so next up. There is another Mage who is a Frost Mage you can recruit. I'm going to try her and see if she is stronger than Marcurio. Rumor is that she's a Dragonborne like you

. I finally found out her location is in a tower Southwest of Riften. I've been searching for last 2 days with no luck. Darklight Tower is the name I believe. I really like Marcurio.... but I want to experience everything first time through so for future games I know how every companion plays firsthand.
Also I learned a couple Mage leveling tricks (I have yet to try but read them).
Conjuration leveling trick. Conjure up a bound weapon and keep it out... while you spam summoning spells and this supposedly will level you.
Restoration leveling trick. Use Illusion Spell which trades life for mana... then immediately use a heal. This will level both Illusion and Restoration (if rumor is true!).
Destruction leveling trick. Keep raising Zombies or Summons... then attacking and killing them with destruction spells.
I'm about to try these tricks and will let you guys know.
