GUIDEMechanics and How to Use

At a Glance

A Middle Blunt Identity that marks enemies for vengeance when hit, then collects those marks through attacks and counters to build The Book of Vengeance. His main payoff is reaching a total Envy Absolute Resonance count of at least 6, turning defense into an S3 Write 'em all down counter that takes hits and collects marks together.

Core Mechanics

  • Defense skill's counter changes (Uptie Ⅳ): At Combat Start, if total Envy Absolute Resonance is 4 or more, the Defense skill Warmup in the East uses S2 Payback with Interest when countering, or S3 at 6 or more (activating from the left-side slot skills on the dashboard, up to 2 times per turn). At Combat Start, he also gains Shield equal to 20/30% of HP lost (once per turn).
  • Combat passive — The Middle Never Forgets (3 Envy Owned; unlocked at Uptie Ⅱ): When he is hit, inflicts 3/5 Vendetta Mark on the attacker (once per turn). When an ally is hit, it inflicts 2, plus 3 more if the ally is a Middle member (once per turn per Identity). At the end of a basic attack skill or counter skill's attack, it spends all of the target's Vendetta Mark (up to 10) and grants that much Book of Vengeance [Sinclair].
  • Book of Vengeance [Sinclair]: Maximum 30. Damage increases by (value)%, up to 30%. As next-turn effects, he gains 1 Blunt DMG Up at 10 or more, +1 maximum Speed and 1 Power Up at 20 or more, and 2 Blunt DMG Up at 30. S3's damage also rises further with Book of Vengeance.
  • Offense Level Up through Resonance: At Combat Start, S2 and S3 gain Offense Level based on the highest Resonance (up to 2/3 for S2 and 3 for S3), doubled if that Resonance includes Absolute Resonance.
  • Middle teams: When Middle allies (Don Quixote's The Middle Little Sister, Meursault's The Middle Little Brother, Heathcliff's The Middle Big Brother) are hit, more Vendetta Mark is inflicted.

How to Use

Pair him with Middle allies, line up Envy skills, and build a total of 6 Envy Absolute Resonance to turn his Defense skill into an S3 counter. The counter collects Vendetta Mark right after it is applied by the hit, building Book of Vengeance most efficiently. The closer the Book gets to 30, the more damage all of his skills deal. S1 Is it You?! restores 5 SP on use (+1 Clash Power instead at max SP), and S1 and S2 also grant Aggro next turn on use. The bonuses on each attack skill for targets with 6 or more Bleed are hard to combine with the S3 counter, so there is no need to aim for them.

E.G.OCompatible E.G.O

  • Hex Nail: S2, S3, and his Defense skill are Envy, making it easy to build Envy Resonance and raise Attack Weight.
  • Tears of the Tarnished Blood [汚血泣淚]: His Defense skill is a counter that grants Shield based on HP lost, likely meshing with a buildup that relies on taking hits.
