Fire Emblem Warriors: Three Hopes - How to Get the Merc Whistle and Who to Give it To

gamerant.com:

The Merc Whistle is a one-of-a-kind item in Fire Emblem Warriors: Three Hopes, and this guide will explain where to find it and who to give it to. While the game lacks Fire Emblem: Three Houses' S Rank Supports, the Merc Whistle acts as a sort of substitute while also granting a powerful gameplay benefit.

Fire Emblem Warriors: Three Hopes is a hack and slash action RPG developed by Omega Force. Set in an alternative timeline of Fire Emblem: Three Houses, the appearance of new character Shez and his mysterious ally Arval quickly throws the plot off of its original course. Acting as a mercenary commander for one of the three factions, players cut their way across the battlefield in true Musou style.

Beginner Tips for Fire Emblem Warriors: Three Hopes

The Merc's Whistle is unlocked shortly after the end of chapter 10 and is a special gift item. It can only be given to a unit if Shez has support rank A with them.

It will trigger a short piece of special dialog when gifted to a unit, and Shez will receive a unique accessory in exchange that, when equipped, replaces a unit's personal ability with that of the unit the whistle was given to.

This makes it possible to further diversify a unit's build and moveset, allowing for an extra layer of customization. As such, choosing who to give the Merc's Whistle to is a huge decision.

The Merc's Whistle also grants a short extra scene at the end of the game which differs depending on whom the whistle was given to.

Using the Merc's Whistle can provide powerful benefits, so from a gameplay standpoint, it's good to pick someone with a unique skill that the player especially likes or that is especially powerful/useful. Examples of these would be:
