A Poise, Burn, and Bleed Identity whose full strength comes from using defense's Phantom Step [殘像步] to kill a House of Spiders ally with Slay the Heavens - Tiansha [天殺], gaining major bonuses in exchange. Requires multiple House of Spiders Identities to realize that potential.
Core Mechanics
Slay the Heavens - Tiansha [天殺]: At Combat Start on a turn she equips the Defense skill Phantom Step [殘像步], she designates the deployed House of Spiders ally latest in team order (up to 2 times per turn, once per Identity; Sinclair's The House of Spiders: The Pinky Apprentice has the lowest priority). When that ally finishes using their equipped skills, is staggered, or has no skill to use, she makes a one-sided attack with Tiansha. It deals fixed damage equal to 120% of max HP and can kill. She gains +1 Base Power for attacks (−1 Offense Level, 4 times per battle), inflicts 20 Bladetrail [Afterimage] on hit, and gains 20 SP and on defeating the target.
Buffs gained from allies' deaths: An effect of the combat passive Saikai [再会]. While a House of Spiders ally is dead, she gains 1 Entanglement, and each fallen Identity's unique effect lasts for the rest of that battle. For example, Outis's The House of Spiders: The Middle Nursefather gives −20% damage taken, and Yi Sang's The House of Spiders: The Index Nursefather makes the final Coin of her basic attack skills Unbreakable. If no Identity steps in from backup or returns, she gains +1 slot for every 3 deaths, up to 3 times. The combat passive Spacetime Afterimage Collapse also increases the number of Phantom Traces inflicted for every 3 deaths.
String Severance [絕緣]: +1 for each dead House of Spiders Nursefather Identity, up to 4. Each point reduces damage taken by 7.5%, and at 1 or more, Phantom Step designates one more ally.
Phantom Trace and Inevitable Termination: At Turn Start, inflicts Phantom Trace on enemies. When an enemy with Phantom Trace is the main target of a basic attack skill, she makes a one-sided attack with Inevitable Termination before use, once per turn. Basic attack skills against enemies with Phantom Trace have all-Unbreakable Coins and +1 Final Power. However, Phantom Trace disappears after Inevitable Termination's attack, so this bonus basically only applies to Inevitable Termination itself (except in Focused Encounters, where Phantom Trace does not disappear).
Dihui Star's Blade and Rend Space: The total Bladetrail she has inflicted, up to 70 and 25 per turn. At 50 or more, she triggers Rend Space - String Connection at the end of the turn, once per battle (unlocked at Uptie Ⅲ). After that, if she has 50 or more at Turn End, one basic skill turns into Rend Space - Echoshear. Tiansha's 20 Bladetrail makes it easier to build, but the 25-per-turn cap means she reaches 50 on turn 2 at the earliest.
How to Use
Deploy multiple House of Spiders Identities, and use the fact that Tiansha targets allies latest in team order by placing the allies you want to defeat first at the back. Defeating Nursefather Identities first increases String Severance and the number of designated allies, speeding up Tiansha. Early on, repeat Tiansha with Phantom Step, building Dihui Star's Blade while gaining buffs from the defeated allies. Once Rend Space is available, attack in combination with Inevitable Termination aimed at enemies with Phantom Trace. Note also that the damage redirection from Saikai does not work unless House of Spiders allies are deployed. There is no need to defeat every House of Spiders ally; in many situations it is better to fight normally after defeating 2–3. If you build around her, Burn teams fit better than Bleed teams.
