Best Team Compositions
Selena is the perfect sub-DPS for Sereniel, who can provide buffs and improve overall damage with her extra attacks. Her Tactical Maneuver card epiphany, which can reset the Tenacity bar, is especially helpful for Sereniel’s kit.
Cassius is the ideal support character for Sereniel. He can provide card draw, and his Triple 0 Quest is a perfect mechanic for Sereniel’s 0 AP Homing Lasers. He also provides some healing to top it off.
Alternative Team Members
| Character | Explanation |
![]() Rei | Can replace Selena as sub-DPS to stack morale and buffs. She can really ramp up Sereniel's laser damage value. |
![]() Nia | Can replace Cassius as a support, providing some card draw skills, damage boosts, and healing. |
![]() Khalipe | Khalipe is a great option, thanks to her ability to provide shields and increase Tenacity damage. With Overpower, Khalipe further boosts the chance to gain Ravage, which Sereniel’s cards rely on to deal more damage. |
Best Cards and Deck Build
Core Character Cards
| Card Name | AP Cost | Type | Effect |
![]() Homing Laser | 0 | Attack | 100% Damage. 1 Afterglow. On Ravage or at the start of the turn, move to hand. |

![]() Cobalt Light | 1 | Attack | 120% Damage to random enemies. Add 1 Hit for each Homing Laser in hand. |
Homing Laser: Pick the epiphany that returns this card to your hand at turn start and when enemies are Ravaged. You'll sacrifice some damage and Afterglow stacks, but you'll consistently get 4+ Homing Lasers each turn. This is your top priority for copying and upgrading.
Shining Core: Pick the epiphany that adds the Initiation tag and turns it into an upgrade card. It gives you 2 upgraded Homing Lasers after Ravaging enemies, letting you play more than 7 Homing Lasers per turn.
Cobalt Light: Pick the epiphany that increases hit count based on how many Homing Lasers you're holding. With the Shining Core setup above, you'll easily maintain 6+ hits, making this the strongest option.

Playstyle Tips and Strategy/How to Play

Sereniel's strength comes from exploiting the Ravage mechanic. Most of her cards become more powerful either when you break an enemy's tenacity bar or when fighting enemies already in a Ravaged state. Your main strategy should be breaking through enemy tenacity quickly to activate bonus effects like extra damage or retrieving cards like Homing Missile back into your hand.
Homing Laser is her key card for dealing massive damage. Make sure to use it as much as possible before triggering Ravage for maximum damage, which is why having characters and partners who can draw cards is ideal for her. After gaining Ravage, unleash hell with resurrected cards and finish off with Cobalt Light.
Make sure to clear your hand before Ravaging an enemy to make room for those Homing Laser cards to return from the Graveyard.
Increase her Critical Chance and Critical Damage as much as you can for the best result.
Strip enemy tenacity fast, trigger Ravage bonuses, and use tenacity-restoring effects to activate those bonuses repeatedly for maximum value.
