FFXIV: Getting the free Wind-up Moon Minion!
This little one has been introduced in the patch 3.5. There was already the Sun one before.
Go to Aleport, take the Ferry to the Isles of Umbra, spot the pot and trade with him: hi-elixir for the Moon minion, elixir for the sun one. These minions are fun - but they won't follow you!
