A Slash attacker whose S2 and S3 gain substantial Power and damage as Courier Trunk - Rodion builds, while a large Shield helps her take attacks. Rupture teams enable her full strength early. In longer battles, defense also offers a way to retreat.
Core Mechanics
Courier Trunk - Rodion: Gained on Coin Ⅰ hit of S1 and S2 and on using her Defense skill (extra below 15). All attack skills gain +1 Coin Power if Courier Trunk is 10 or more or the target has at least 6 Rupture (+1 per 10 Courier Trunk or 6 Rupture, up to 2, at higher Uptie). S2 gains +2% damage per Courier Trunk (up to 40%), and S3 gains +2/4% (up to 40/80%).
S2 Courier Trunk - Gadget Reveal (core): 3 Coins. Gains Courier Trunk, grants 1 Haste next turn on Coin Ⅱ Heads Hit (+1 more at 15 or more Courier Trunk), and Coin Ⅲ inflicts Defense Level Down. If the target has 15 Rupture and at least 3 Rupture Count, it does not consume Rupture Count on hit.
S3 — I Trust Ya, Polu!: If the target has 15 Rupture and at least 3 Rupture Count, it reuses its last Coin instead of inflicting Rupture Count. Otherwise, Coin Ⅱ adds +3 Rupture Count (+1 more per 10 Courier Trunk, up to 2). At 15 or more Courier Trunk, Coin Ⅲ deals +15/25% damage.
Combat passive — Speedy Delivery (4 Gluttony Owned; unlocked at Uptie Ⅱ): At Turn Start, if she has 6 or more Speed or Haste, she gains Shield of (Courier Trunk ÷ 2 / Courier Trunk)% of her max HP, up to 15/20%. On retreat, gives 1 Clash Power Up to 2 allies next turn (+1 turn of duration per 15 Courier Trunk, up to +2).
Retreat: If Courier Trunk is 15 or more at Combat Start, the Defense skill Courier Support & Control Sequence activates as Just... a Strategic Time Off!, and she enters Strategic R&R Mode (retreat) at Turn End. When she rejoins in consecutive battles, Courier Trunk is halved (once per battle, rounded up).
How to Use
Early on, build Courier Trunk with S1, S2, and her Defense skill (it builds faster up to 15), and attack mainly with S2, which grows stronger as it builds. Against enemies with 15 Rupture and 3 or more Rupture Count, S3's last Coin is reused, so setting up the condition in a Rupture team before firing it deals big damage. S2's Haste also makes Speedy Delivery's Shield condition easy to meet. Once Courier Trunk reaches 15 or more, placing her Defense skill makes her retreat at Turn End regardless of whether the counter was used, so from then on it is a choice between continuing to attack and retreating. Above 30 Courier Trunk, self-damage begins (not mentioned in the Identity's effect text), but most battles end without her retreating. Think of retreat as an option for long fights or for swapping with a backup unit in consecutive battles.
