A slow-starting Poise and Rupture Identity that gains Serpent Arm, builds Poise, and attacks through enhanced critical skills. Aim for 20 Poise, giving 100% critical chance, and maximum Coin Power on every skill.
Core Mechanics
Serpent Arm (Poise source): Maximum 3. At Turn End, grants 3 Poise and +2 Poise Count for the next turn. When using a basic attack skill, she gains 5 Poise if the target has Rupture. It decreases by 1 at Turn End. She gains 3 Serpent Arm on using S3 Serpent's Mortal Flurry, 3 Serpent Arm for the next turn at Combat Start of the Defense skill Reversal Kick, and 1 on Coin Ⅲ Critical Hit of S2 (Uptie Ⅳ).
Poise and Rupture bonuses: All attack skills gain +1 Coin Power if her Poise Potency plus the target's Rupture Potency is 10 or more (+1 per 10, up to 2, at higher Uptie; +2 at a total of 20 is Uptie Ⅳ). Each Poise gives 5% Critical chance, so 20 Poise guarantees Critical Hits.
S2 — Snake Fang: 3 Coins. On Clash Win, +2 Rupture Count on the target and +1/2 Poise Count on herself. Coin Ⅲ inflicts Deathrite【Venom】, and at 30 or more Poise, spends 10 Poise to reuse the Coin once.
S3 — Serpent's Mortal Flurry: A 3-Coin Unfocused Volley (from the second Coin on, targets are random). Clash Power rises by her Serpent Arm. On Coin Ⅲ Critical Hit, the Coin is reused (up to 2 times per skill) and the target's Deathrite【Venom】 decreases by 1.
Combat passive — Heishou Mutation [Si] (5 Gluttony Owned; unlocked at Uptie Ⅱ): +5% damage while she has Serpent Arm, and +5% more if the target has Deathrite【Venom】.
How to Use
Early on, secure Serpent Arm with S3 or her Defense skill (the Defense skill takes effect at Combat Start, so it does not need to Clash with an enemy attack). Serpent Arm's 5 Poise is only gained when the target has Rupture, so pairing her with allies whose final Coin inflicts Rupture is important. Her ways to maintain Poise Count are Serpent Arm, S1 (+1/2 on use), S2's Clash Win (+1/2), and S3 (+2 on Coin Ⅰ hit; Coin Ⅱ also grants 2 Poise), so use S2 in Clashes it can win and send S1 to one-sided attacks. Firing S3 once Poise has built up reaches up to 5 Coins through Critical reuse. Deathrite【Venom】 is enough as a passive condition and is not the main thing to aim for. Her Defense skill has low Clash Power (up to 10/13). She is also fragile herself, so avoid relying on the Defense skill too much. She shows her true strength in long fights rather than short ones.
