Tap Battle: Illusory Dungeon

Tap Battle is a periodic event type that appears in Fire Emblem Heroes.

Overview
Tap Battle is an event that focuses on simple rhythm gameplay instead of the standard Fire Emblem Heroes strategy gameplay. Players take a team of four characters into a series of battles against foes that approach in time with the music. The player must tap the screen as an enemy closes in to strike in order for the party member they're attacking to strike first and defeat them. In Casual Mode, the player taps an icon representing the Summoner and Feh for each attack action. In Expert Mode, the player must tap next to each party member in the player's line-up for that party member to strike.

In Tap Battle, character levels are ignored and all characters fight at full power. Skills and other character and class-specific abilities are also not taken into account. A reward is given for completing each round of Tap Battle for the first time, but no rewards are given on subsequent attempts. A letter ranking is awarded based on the player's top combo score. Unlike the standard game modes, playing Tap Battle does not cost stamina.
