Was playing as a stealthy mage:
I had just finished exploring a few dungeons, Fort Amol full of Mages, and Convangr Cave full of spiders and some Vampires. Upon leaving the cave, I was attacked by a Dragon. Upon looting it's various body parts, I realized I was overburdened.
"Lydia, get the f*** over here." I said aloud, as she ran over to me.
"I'm swoooorn to carry your burdens." I mocked as she said the same in her snarky tones. I barely open up her inventory anymore just to avoid her incessant nagging tone.
I dump a bunch of seemingly nondescript loot on her, including the dragon parts I just looted.
Thinking nothing of my choices, I continue to frolic on my merry-mage way towards Eldergleam Sanctuary, when I get ambushed by a pack of Wolves. I raised my firey hands and prepared to burn them to oblivion.
This is where I suddenly went "Wtf?!" and things got a little weird. Out of nowhere a Familliar erupts, making me look around wildly for the mage attacking me. This is the point when the Flames come blasting from behind me, killing all of the wolves.
With the wolves laying dead on the ground and a familliar sitting there and chilling, I turn around to look at Lydia to make sure a mage didn't eat her.
Oh wait, apparently Lydia has been studying from me. Why? She was DUAL-WIELDING two Flame Staves. And must have switched out at some point because she was also carrying a Staff of Familliars. I've given her staves before and never had her use them, which is why I was so flabbergasted.
A warrior class follower, with good quality weapons and armor, decided to dual-wield staves. Why? My theory is she was jealous of my Fireballs.
At this point I couldn't stop laughing for a good couple minutes, and my roommate got a good laugh out of it too.
Thought I'd share this, and see how many other people have an Epic Mage Lydia as their companion!
