Mumei is a collaboration character from the series Kabaneri of the Iron Fortress. She is joining as a DPS crew member. Capable of doing multi-instance hits and decent AOE coverage with her Ultimate skill, she can also dodge attacks to generate cost. With great support, you are sure to consistently produce satisfying work with her
Playstyle and Key Mechanics
Mumei is a Red Card-focused DPS, greatly utilizing [Rend] and [Slash]; thanks to that, she can unleash more hits than usual. Unlocking her Resonance will help her juggle her cards
Let's begin with [Butterfly Dance]. This is a red card that deals 6 instances of damage to the target, not only that it also has the chance to trigger [Ignite] upon hit.
Next is [Ghost Dance], a skill that can reduce the target's ATK and DEF. This also inflicts [Injure] to increase the enemy’s DMG taken and inflict [Stun] to interrupt. Each hit is capable of inflicting [Slash] for additional damage.
Lastly, her Ultimate [Ephemeral Dance,] a 12 instance of damage capable of [Rend] and triggering [Wildfire], this also has a chance to trigger [Slash]
Investment
There are 2 important stopping points on obtaining duplicates of her: it's her Awakening 2 and Awakening 5. If you are unable to reach it due to a lack of currency, do not push it; she’s still capable at her base Awakening.
Awakening 2 - Adds an effect to [Butterfly Dance] and [Ghost Dance] to generate cost and heal from its damage dealt. Additionally, upon using [Ephemeral Dance] or dodging an attack, she can heal allies.
Awakening 5 - Using any Leader Skill or Ultimate will trigger [Butterfly Dance] or [Ghost Dance]. This makes use of her Awakening 2 more often. Additionally, using [Ephemeral Dance] will debuff all the enemies to take more damage.
Resonance
Resonance 1 — Adds [Butterfly Dance] or [Ghost Dance], respectively, depending on which skill is used.
Resonance 2 — Gives her a chance to dodge incoming attacks, and each successful dodge restores cost.
Resonance 4 — Always have a [Butterfly Dance] in your hand when the battle begins or the deck is shuffled. Mumei then drains an Ally's HP for him to gain Final DMG bonus and gain [Berserk] and [Hyperarmor] for 12 seconds. This has a similar effect to Ikoma.
Resonance 5 — Increases the number of attack segments for [Butterfly Dance], and after using [Ghost Dance], it will also increase [Ephemeral Dance]’s damage.
