FaustHeishou Pack - Mao Branch Adept
Use her S3 or defense on turn 1 and every 3 turns after to maintain her 
Strider【Mao】 giving her 5 
Haste every turn. All her skills gain more Power or damage based on speed and some get additional buffs at 10+ speed, so always keep it up.
Once her passive is active, she starts gaining 
Tianjiu Star's Blade whenever Deathrite effects or her 
Assist Defense are triggered. At 10+ stacks, her S3 is upgraded. If you're using a mostly Heishou team, having everyone use their S3 or defense on turn 1 to activate their buffs gives you enough 
to trigger her passive by turn 2.
Use her defense skill to give her Assist Defense which lets her redirect an unopposed attack on an ally (excluding herself) to herself. At 10+ stacks of Tianjiu Star's Blade, she consumes 10 to use her S3-2 when redirecting an attack. Using this every turn is self-sufficient to always trigger her S3-2 once you hit 10 Tianjiu Star's Blade for the first time.
Inflicts 
Deathrite【Haste】 with both versions of S3 and inflicts 
Deathrite 【Fissure】 with S3-2. Deathrites trigger additional effects on the target whenever 
Rupture is triggered with a certain condition, and deals additional damage based on Rupture when fully consumed. Deathrite【Haste】 inflicts +1 Rupture Count if the attacker had 10+ Speed, while Deathrite 【Fissure】 inflicts 1 
Bind. When Deathrite 【Fissure】 is consumed, she inflicts 
Mark of Decay on that enemy, increasing damage taken from or Deathrite effects. The application and consumption of these Deathrite effects on her S3-2 is what guarantees the self-sufficiency of her Assist Defense always triggering it.
Combos with [Hong Lu] The Lord of Hongyuan's S3. The buff gives him -5% damage received.
