Project Bronze Forever Catch the Regi Trio
Frostveil Catacombs puzzles, three chamber doors, and one chance each for Regirock, Regice, and Registeel.
Regirock, Regice, and Registeel sit behind Frostveil Catacombs, not behind a Port Decca yacht. Project Bronze Forever treats each chamber as a one-chance fight, the same rule as legendary birds. This page is the official catacombs route: Rock Climb down, two party slots, a button order, a Rock Smash wall, then three overworld doors. Plan on about seven badges so Harvest (Rock Climb) and Crater (Rock Smash) are already done. The gym walkthrough and controls pages list those gates. Play the live copy from the official play page.
Save in Options. Turn autosave off before you step on a chamber pad. Dusk Balls are the ball this hunt uses. If a Regi faints, that file does not get that Regi again.
Entering Frostveil Catacombs
Go to Frostveil City. Beside the Pokemon Centre, use Rock Climb and climb down into Frostveil Catacombs. If there is no climb prompt, you do not have the Harvest Badge from Fissy in Fluoruma (gym 6). Frostveil’s gym is Zeek, Dark-type, Contrast Badge, Surf — that is gym 7, and it is a 2D platformer, not the catacombs entrance. Do not walk into Zeek’s gym looking for Regirock.
Puzzle 1: Girafarig first, Dunsparce last
The first door tells you the requirement in its text. Put Girafarig in the first party slot and Dunsparce in the last party slot, then interact again.
Girafarig: Route 5. Dunsparce: Old Aredia.
Catch them before you drop into the hole if you do not already have them. The door is not a type puzzle and not a level puzzle. Wrong slots mean the door stays shut. Swap in the Menu, then try the door again.
Puzzle 2: button colors
Press the buttons in this order: red, green, red, blue, blue, yellow, green.
That sequence is the whole puzzle. If a room resets, start from red again. Do not invent a second code; this is the order from the official video.
Puzzle 3: Rock Smash wall
Smash the wall. That is gym 5’s HM from Prince Ryan’s Crater Badge in Aredia. If you cannot smash, leave the catacombs, finish Aredia, and come back. There is no alternate pickaxe.
Final room: three chamber doors
The floor grid in the last room opens three doors. Each door is a different overworld chamber. You still have to travel to the chamber after the grid; the catacombs are the key, not the catch arena.
Regirock — Calcite Chamber. From Brimber City take Route 6 and follow the right path.
Registeel — Martensite Chamber. Grove of Dreams outside Rosecove, up by the red Tree of Fire.
Regice — Dendrite Chamber. Route 15 near the Frostveil gate, go left.
Go to one chamber at a time. Save in front of the legendary, autosave off, throw Dusk Balls. Repeat for the other two. Bring a team that can chip Rock, Steel, and Ice without knocking them out; use the type chart. Your starter is not a required key for these doors — Girafarig and Dunsparce were the keys.
After the trio: Regigigas
When all three are in the party, Regigigas is available later at Titans’ Throng. This page does not add a second video or extra puzzle steps for that fight. Treat it as a follow-up that needs the trio caught, not as a fourth catacombs button. Keep the three Regis; do not trade them away if you want that later encounter.
Prep that is easy to skip
You want Rock Climb (gym 6) and Rock Smash (gym 5) before the hole. Seven badges is the practical checkpoint; gym 8 is not required to open the grid. Surf from gym 7 is for Crescent and for water, not for the climb beside the Centre. Codes from working codes can restock Dusk Balls after Silvent; redeem them with how to redeem. Story context for Brimber and Rosecove (the two cities you travel back to for Calcite and Martensite) is on Team Eclipse and gym leaders.
If the climb vanished after a re-upload, confirm the place on game status and Discord rather than assuming Harvest was wiped. Saves are designed to persist. For other one-chance hunts after the trio, use Volcanion, Rotom, Victini, and Eeveelutions. None of those replace Girafarig in slot one. Slot one is Girafarig, slot six is Dunsparce, buttons are red-green-red-blue-blue-yellow-green, then smash the wall and walk to Calcite, Dendrite, or Martensite with autosave already off.
