The Shovel Knight amiibo was first announced August 27th 2015. It unlocks features in the Wii U, 3DS and Switch versions of Shovel Knight: Treasure Trove, a boss fight in Azure Striker Gunvolt 2, as well as a few miscellaneous features in other Nintendo amiibo compatible games.
To be used with the original 3DS, 3DS XL, or 2DS consoles, a NFC Reader/Writer accessory is required.
Features in Shovel Knight: Treasure TroveEdit
The main feature of the Shovel Knight amiibo is Custom Knight. With this Shovel Knight levels up by collecting Gold. Each level unlocks more health and magic, relics, charge attacks, abilities, and cosmetics. Custom Knight data is saved to the amiibo.
Note: Custom Knight is only playable on the Shovel of Hope campaign.
Previously Co-op was exclusive to the Wii U version of Shovel Knight and could only be accessed via the Shovel Knight amiibo, however on January 11th 2017, Yacht Club Games announced their intention to release Co-op Mode on all platforms and removing the need for a Shovel Knight amiibo to activate it on the Wii U. As this feature is now available on all platforms, and the amiibo is no longer needed to access it.
Co-op mode is also compatible with Custom Knight although for both players to use Custom Knight requires the use of two different amiibo.
Scanning the amiibo at the challenge screen unlocks new challenges for Challenge Mode. Unlike with the other amiibo usage this only needs to be scanned once to permanently unlock the challenges. The 3DS version unlocks 5 new challenges centered around Custom Knight, but the Wii U and Switch versions have the 5 regular custom knight challenges, as well as 5 additional Co-op challenges.
On March 1st 2017, Yacht Club games announced Madame Meeber, a fairy-godmother themed character for the amiibo, who is capable of summoning a fairy companion for the player after scanning the amiibo. The only fairy available currently is the Fairy of Shovelry, designed around Shovel Knight, and is available in all campaigns. The fairy is purely cosmetic and doesn't affect the gameplay whatsoever.
Azure Striker Gunvolt 2Edit
Scanning the amiibo in Azure Striker Gunvolt 2 unlocks a boss battle against Shovel Knight. This was added due to Yacht Club Games publishing Azure Striker Gunvolt: Striker Pack (a physical bundle of both Gunvolt games) in North America.
