The Lost Riches event in Genshin Impact allows you to earn Iron Coins that you can use to buy all manner of items in the event shop. When all other options are exhausted and you have searched all the Treasure Areas, you will find that you have just enough Iron Coins left over to buy one Mini Seelie.
There are three different types available, so which one should you choose? Truthfully, there is little difference between the Mini Seelie; the only thing that is different about them is their color. You can pick a blue one, a rose one, or a gold one.
Each has a slightly different write up in the game, but they all look the same, except for the color. If you want to visualize it in your head before choosing, then keep in mind that they look exactly like the Treasure Seeking-Seelie that has been helping you track down Iron Coins throughout the event.
You can equip the Seelie as a Gadget from your inventory, then call it out whenever you wish. They are pets and will float near your character and follow you around while you play the game, but they do not serve any other purpose. They do not provide any buffs or advantages, and they don’t have any hidden mechanics that we are aware of.
Which one you choose is entirely up to you, and will mostly depend on which color you prefer. It should be noted, the rose-colored one seems to stand out the most in the game and is quite bright, but we opted for the gold simply because it’s the color of luck in Genshin Impact, and we could use all the help we can get on those 5-Star pulls.
