The festival banner runs a higher legendary rate and a much shorter guarantee than the standard Exalted Summon. Cassia Arden — the highest-ATK hero in the game — claims half of every legendary pull while it lasts.
Meroveil is in pre-release. Everything here is read from the game's live data, last verified 2026-08-30 — but balance updates ship faster than this guide, so treat every number as subject to change until launch.
The roster
38 summonable heroes across five elements. Eighteen named legendaries lead them, each with a faction, a story and a place in your formation.

The Abyssal Dragon: 500 million HP, worn down by the whole server.
Up to 50 members, with guild raids and territory war.
Chapters IV – VIIIFive more chapters170 stages in all. The campaign costs no energy, and a cleared stage can be swept.
