Granado Espada Clasique #30 Tetra Ruins Dungeon Quest Treasure Golem

Concept
There are 5 special boss rooms you can find on Granado Espada Classique.
You can access the boss room via the pioneer statue at the last dungeon level. Entrance is free. Each room contains its own special boss, which respawns every 3 hours. List of bosses and rooms:
Al Quelt Moreza, Hollow - Enter from Al Quelt Moreza, Arcade. Boss: Dilos Latemn.
Tetra, Antiquities Room - Enter from Tetra, Golden Road. Boss: Treasure Golem.
Porto Bello, St. Cathrina Saloon - Enter from Porto Bello, The Hold. Boss: Chimera
Instead of waiting ordinary spawn cooldown, you can summon the boss using a treasure chest placed in each room. Boss summon requires dungeon key, there is no cooldown on summon.
Dungeon room keys can be obtained from normal dungeon bosses' loot.
Also, there are two high-level boss rooms:
Jaquin, Corridor of Assize - Enter from Jaquin, Gehenna Bridge. Bosses: Chrysalis and Dr. Fran Mothein.
Room of The Dead - Enter from Skullic Dungeon, 3F. Bosses: Ravyn’s Heart of Room of the Dead and Ravyn the Unholy.
These bosses cannot be summoned and their respawn time is 3 hours. After killing the first boss of the room, the second will spawn automatically. To enter high-level boss room, you will need a key.
