How about the obvious?(SCIENCE)

Quest Unlocked: How about the obvious?
Create an illusion barrier to go practice in. Seriously, do it, John. Hell, I’ll throw in a cool reward if you do. I’m tired of watching you this closely to ensure that no one walks in on you practicing magic and I have to smite you. I have other things to do.

Reward: One cool item. Seriously. It’s cool.

Quest Complete: How About the Obvious?
You followed my exact wording and summoned an illusion barrier. Honestly, you don’t deserve this, but here. It’s been on my shelf gathering dust for the longest time, and I miss the guy who used these. Make his memory proud.

Reward: Lunettes de Lecture Magiques
