A Blunt Rupture Identity that builds Courier Trunk to improve Coin Power and Rupture Count application. Finish enemies with at least 15 Rupture and 3 Count using S3 Poludnitsa... I trust you! Avoid using S1 or S2 on enemies in that state.
Core Mechanics
Courier Trunk - Sinclair: He gains 1 with Coin Ⅰ of S1 Courier Trunk - Decay Hammer (1 more below 15) and 1 with Coin Ⅰ of S2 Courier Trunk - Demolition Gadget (2 more below 15). All attack skills gain +1 Coin Power based on Courier Trunk or the target's Rupture (up to 2; the condition changes with Uptie).
Enemies with 15 Rupture and 3+ Count: Against enemies in this state, S1's and S2's on-hit effects do not inflict Rupture (or Count) and inflict 2 Defense Level Down instead (once per Coin). S3 does not inflict Rupture or Count, but gains +2/4 final Coin Power. If the target has 15 or more Rupture, the final Coin gains +3/4% damage per Courier Trunk, up to 90/120%. However, the loss from S1 and S2 no longer maintaining Rupture is larger.
Rupture Count: S1 inflicts 2 Rupture Count with Coin Ⅱ (1 more at 15 or more Courier Trunk). S2 inflicts 2 and 3 Rupture with Coins Ⅱ and Ⅲ, increasing Rupture Count by 1/2 only at 15 or more Courier Trunk. S3 inflicts 1 Rupture Count with Coin Ⅰ plus 1 per 10 Courier Trunk, up to 2/3.
Maintenance (retreat): With 15 or more Courier Trunk, his Defense skill activates as W-wait, I need to do some maintenance...! at Combat Start, granting Shield based on Courier Trunk, and he enters Strategic R&R Mode at Turn End. When returning from retreat in consecutive battles, Courier Trunk is halved (once per battle, rounded up).
Combat passive — A moment, please... (4 Gluttony Owned; unlocked at Uptie Ⅱ): At Turn Start, if he has 6 or more Speed or Haste, he gains Shield of (Courier Trunk)% of max HP, up to 20%. On retreat, gives 1 Clash Power Up to 2 allies next turn (+1 turn of duration per 15 Courier Trunk, up to +2).
How to Use
Build Courier Trunk with S1 and S2 while stacking Rupture. From 15 Courier Trunk, S2 can also increase Rupture Count. Once the enemy reaches 15 Rupture and 3 or more Count, stop landing S1 and S2 on it and aim to finish with S3. In consecutive battles with backup units, use the retreat through his Defense skill once Courier Trunk has built up, buffing allies and keeping the fight going.
