Endgame Dungeons

Infernal Dragonspire and Blossom Manor are the Royal Level 25 endgame instances introduced with the Genesis–Kheldor merge update.

Dungeon Comparison

Dungeon	Usecase
Infernal Dragonspire	Obsidian Beads, Royal Key-Exchange, New Suit-Cards, Grid-Stones
Blossom Manor	Royal Key-Exchange, Royal Key-Upgrade, Grid Stones

Both dungeons use custom designed bosses, visual effects, music and unique time-based BossPhases. They are intended for coordinated parties that have already completed the whole Content before.

Do not enter only because the Royal Level requirement is met. Finish the relevant equipment, permanent power-ups and mechanic preparation first.
