Overall
Serennia is an obsessive single-target specialist who binds herself to whichever enemy holds the highest attack rating, her Dearest. Her ultimate flags that target for exclusive focus and drains their health into an undispellable shield that locks down their skills, converting any leftover value into damage against every other enemy. Her active skills deepen the bond: she disables the Dearest while cannibalizing their health into team-wide damage, marks them to block outside healing and shields, and repeatedly saves them from fatal blows by sacrificing the rest of the enemy team's health instead. Using her abilities triggers an Enthralled state that cuts her damage taken, spreads her attacks to everyone, and punishes active skill use against her. Once the Dearest is finally allowed to die, she turns them into an exploding, taunting phantom.
Skills
Fatal Love Pact
UltimateDesignates the highest-attack enemy as her Dearest and focuses normal attacks on them. Drains their health into an undispellable shield that locks their skills; leftover value becomes AoE damage. Entering an Enthralled state afterward cuts damage taken, spreads her attacks to all enemies, and punishes active skill use.
Sinking Affection
ActiveInflicts heavy health loss on her Dearest, rooting them in place and forcing them to face her. Converts part of that loss into AoE damage on other enemies while healing her Dearest slightly. Resisting drains their energy and Enthralls her; retaliating afterward turns the heal into bonus AoE damage instead.
Lovesick Requiem
ActiveMarks her Dearest, causing health loss and blocking healing and shields they receive. An invincible or untargetable Dearest Enthralls her instead. Enemies that buff the Dearest are struck by her spines, losing health and permanently losing attack rating, up to 3 stacks, after which they take increased damage from her.
Love's Burial
ActiveSacrifices the other enemies' health to save her dying Dearest, stunning, shielding, and silencing them up to 3 times per fight, permanently reducing the damage and health loss she takes from them. On the final kill, she turns invincible and transforms the Dearest into an exploding, taunting phantom.
Signature Item
Deepwater Spines
Extends Enthralled stuns on Dearest's death, boosts crit rating and stuns at range, traps at close range, and permanently steals attack rating whenever Enthralled.
Furniture

Passive: At the start of battle, Serennia designates the enemy hero with the highest initial Attack Rating as her Dearest (excluding the enemy Serennia). While the Dearest survives, Serennia's normal attacks will target only them. Active: Inflicts health loss to absorb 20% of Serennia's Dearest's max health (max 900% of Serennia's Attack Rating) and converts it into an undispellable shield called "Aquatic Cage" for 2s, which prevents the Dearest from using skills. When the Aquatic Cage expires, any remaining shield value is converted into Dragonspeak Damage and dealt to all other enemies. If the Dearest is the only surviving enemy hero, the shield will not be applied. After using her Ultimate, Serennia enters the Enthralled state for 7s. While in the Enthralled state, Serennia takes 75% less damage, her normal attacks target all enemies, and her spines awaken. The spines attack any enemy that uses an active skill other than an Ultimate, causing them to lose health equal to 350% of Serennia's Attack Rating and take 45% more damage for the next 6s.
Serennia first inflicts health loss equal to 400% of her Attack Rating on her Dearest, renders them unable to move or use active skills other than their normal attack for 8s, and forces them to face her. Next, 35% of the health lost by her Dearest is converted into Dragonspeak Damage and dealt to all other enemies (max 650% of Serennia's Attack Rating), while her Dearest recovers up to 10% of their max health (max 200% of Serennia's Attack Rating). If Serennia's Dearest dies, these effects will target the default unit for normal attacks.
Serennia applies a special mark on her Dearest, inflicting health loss equal to 350% of her Attack Rating. The mark lasts for 8s and cannot be dispelled. While the mark is active, whenever Serennia's Dearest receives healing or shield effects from any unit besides Serennia, the healing or shield effect is reduced by 75%. If Serennia's Dearest dies, these effects will target the default unit for normal attacks.
When her Dearest takes fatal damage, Serennia evenly sacrifices the health of the other enemy heroes, inflicting health loss on them. She also heals her Dearest for 30% of their max health, up to 850% of Serennia's Attack Rating. At the same time, her Dearest is stunned for 2s, becomes invincible and untargetable, and cannot cast skills. This effect can trigger up to 3 times. It does not apply to bosses.
Deepwater Spines
Enhances: Possessive VisionWhen her Dearest is killed, Serennia remains permanently in the Enthralled state, and her spine attacks stun the target for 1s.
When her Dearest is killed, Serennia remains permanently in the Enthralled state, and her spine attacks stun the target for 2s.
If her Dearest is beyond a certain range, Serennia grows anxious, increasing her Crit Rating by 20. Her next critical strike also stuns the target for 4s. This effect can trigger once every 2s.
If her Dearest is within a certain range, Serennia becomes exhilarated, and her next normal attack traps the target inside her Aquatic Cage for 2s. This effect can trigger once every 6s.
At the start of battle, Serennia enters the Enthralled state for 7s. Each time she enters this state, she permanently steals 15% of her Dearest's Attack Rating (stealing a max 100% of Serennia's initial Attack Rating).
Enhances: Resonant Tide
Whenever Serennia's Dearest receives healing from an enemy, the enemy unit that provided the healing will be attacked by her spines, inflicting health loss equal to 400% of Serennia's Attack Rating and preventing the unit from receiving healing for 8s. This effect can be triggered once every 0.5s. If the enemy unit is a boss, they suffer an extra spine attack every 2s.
If Serennia's Dearest takes damage from any source other than Serennia, 50% of that damage is transferred evenly to the other enemies. In boss battles, the damage is not transferred, but instead increased by 50% and dealt back to the boss.
While the mark is active, any enemy that applies an attribute buff to Serennia's Dearest is hit by her spines, suffering health loss equal to 400% of Serennia's Attack Rating and permanently losing 15% of their Attack Rating (max 3 stacks). This health loss can be triggered once every 0.5s. At 3 stacks, that enemy hero earns Serennia's grudge, permanently increasing the damage and health loss they take from her by 60%.
When her Dearest is killed, Serennia becomes invincible and untargetable for 1s, and turns them into an Abyssal Phantom for 8s. The Abyssal Phantom taunts enemies that deal damage to Serennia. When it expires, it explodes, inflicting health loss equal to 500% of Serennia's Attack Rating on enemies within range.
