Retainers

[MistakeNot]

For a list of what you can send your retainer to get:

Note, while the amount says 10 it tends to start on 5 when retainer just gets on the level and then grows to 10 as they level past it.

If you send your retainer out on a Quick Exploration I think it can bring back nearly anything. Including rare drops if you are really lucky.
