Looking for an Agent? Here's where to find them.

You get the possibility of a Chaos Scroll from the "Today's Mission!" quest. Agent E gives you a box that gives a random prize. The Chaos Scroll only works on Agent equips though, and it expires after 24 hours if you don't use it. ;\

My friend and I got 10+ of the Intelligence Scrolls in one HPQ, so it isn't too hard to get those.
