How to Play Sereniel

Ravage Enemies to Gain Various Benefits

Chaos Zero Nightmare - Sereniel HTP 1.png
All of Sereniel's cards benefits from Ravage, either when triggering it or when the enemy is already in that state. Make sure to remove the enemies tenacity bar as fast as possible to take advantage of effects such as Homing Missle returning to your hand or dealing more damage.

Use Selena to Refresh Enemy Tenacity Bar

Chaos Zero Nightmare - Selena Tactical Maneuver Card
One of the cards that synergizes well with Sereniel is Selena's Tactical Maneuver. This lets you recharge the tenacity bar of the enemy which enables Sereniel to decrease the tenacity of the enemy again to gain the benefits of ravage multiple times depending on how many copies you have.

(also >>5) Yeah this site's guides aren't that great especially for CZN, though I'll give that a pass since there's so many ways to go about setting up your characters in this game

Anonymous about 5 hours

s tier, because apparently summoning 5 to 20 beams per turn depending on the amount of enemies isn't worthy of anything higher
