Mercedes is a member of the Azure Gleam, having magical prowess as her strong suit. Giving her the Merc Whistle would provide you with the unique ability, Radiant Love. This ability acts as a support ability. When you attack, you will see the ability gauge filling up. That gauge restores your HP and, once fully filled, damages enemies and heals allies upon use.


She is a member of the Azure Gleam. Gifting her the whistle would give you her unique ability, Courageous Aria. this works just Radiant love. When the unique ability gauge fills, it reinforces your defenses and allies. This allows them to handle high damaging abilities without burning into a crisp.

She is a member of Azure Gleam. If you give her the Merc Whistle, she will provide you with the ability Icy Plunge. IT allows you to release an AOE attack. It displaces the enemies close to you, and those in the air explode to deal ice damage in that area.

Lorentz is part of the Golden Wildfire. She gives you the ability, Rondo of Roses. This ability also has an Ability gauge. Once this gauge fills, it allows you to pull in enemies a little far from you. It can be an excellent opener to initiate fights or end them.


Hilda is a long-standing member of the Golden Wildfire. She gives you the ability named Lightning Bound. Holding the button increases your damage by a little and adds the lightning element to them.

Next up, we have Marianne. She is a member of Golden Wildfire. Her unique ability is Snowslip. Once you have 300 hits, it spawns ice orbs that damage your opponents. The orbs keep on increasing as your hit count rises.

These are some characters that give you particular powerful abilities upon gifting them the Merc Whistle. There are other characters as well, but they fall pale compared to these abilities. It is up to you to choose which ability suits your team best and cover up the holes in it. Our recommendation would be to go for Divine Pulse, which you get from Byleth.

Divine Pulse is too good of an ability to pass up. The ability to pause time can allow you to take a breather in fights and hit back with a more potent attack than your enemies to gain the upper hand. However, if you think this ability isn’t for you, the other might be more to your liking.
