pokemon rejuvenation flash: What It Unlocks

Flash is a key exploration tool in Pokémon Rejuvenation. It illuminates dark cave interiors, making switches, ledges, items, trainers, and branching paths easier to identify. The move is especially useful when the story sends you toward research areas containing Zubat and Crobat encounters.

Video Highlights:

  • Finding the route toward the casino and the Flash purchase.
  • Obtaining a Coin Case before spending Coins.
  • Returning to the cave and activating Flash for better visibility.
  • Exploring the research area after the lighting problem is solved.
Navigation Tip

Use Flash before attempting the cave’s puzzle routes. Better visibility helps you distinguish doors, vents, ledges, item balls, and blocked passages without wasting movement.

The important distinction is that Flash is not collected from the cave itself. You must leave the exploration route, visit the casino, secure access to its prize counter, and then return with the TM.

How to Get the Coin Case and Casino Access

The Coin Case is the first practical hurdle. In the Chrisola Hotel Casino, an NPC-related event involves a Coin Case being discarded through the sewer system. Follow the event route rather than searching every hotel room for a hidden item.

The sequence is easier if you prepare before entering the casino area:

  • Heal your party before moving between the hotel, casino, and sewer routes.
  • Keep a few spare healing items available for the return trip.
  • Check your Key Items after completing the sewer interaction.
  • Return to the casino only after confirming that the Coin Case is registered.

Before the Event

  • Visit the hotel casino area
  • Check nearby NPC dialogue
  • Save before entering the sewer route

During the Event

  • Follow the discarded Coin Case
  • Search the sewer room carefully
  • Confirm the item was collected

Afterward

  • Return to the casino
  • Inspect the prize counter
  • Save before spending Coins
Do Not Skip the Key Item

The casino counter will not solve the Flash objective until the Coin Case event has been completed. If Flash is unavailable, verify the Key Items pocket before leaving the area.

The Coin Case also helps prevent a common mistake: assuming that regular money is accepted at the prize counter. Casino purchases use Coins, so your standard currency balance does not replace the required amount.

Step-by-Step Flash Purchase Route

Use the following route when you want the shortest reliable process from discovery to cave exploration. The order keeps the casino objective separate from the later research task.

1

Enter the Chrisola Hotel Casino

Travel to the hotel casino and speak with the relevant NPCs. Advance the Coin Case event instead of immediately checking the prize counter.

2

Follow the Coin Case to the Sewer

Enter the sewer route connected to the event and inspect the location where the Coin Case was discarded. Pick it up and confirm it is added to your Key Items.

3

Return to the Prize Counter

Go back to the casino and open the prize exchange. Look for TM70 Flash and verify that you have at least 1,000 Coins.

4

Purchase TM70 Flash

Buy Flash, then check your Bag. If your intended user cannot learn it, select another compatible Pokémon rather than assuming the TM is missing.

5

Revisit the Dark Cave

Return to the cave near the research area and use Flash when prompted. Continue through the lit passages and investigate the Crobat encounter area.

Route Complete

Once TM70 is in your Bag and the Coin Case remains available, the main Flash objective is finished. You can now return to the cave without repeating the casino event.

Using Flash in Dark Caves

After obtaining Flash, return to the dark cave connected with the research sequence. The goal is not simply to brighten the screen; visibility makes the cave’s structure readable. This matters when several paths appear to loop or when environmental objects control access to new rooms.

Use a methodical approach:

  • Activate Flash before moving deep into the cave.
  • Mark doors and vents mentally as you pass them.
  • Check side paths for items before committing to the main route.
  • Watch for ledges that create one-way movement.
  • Treat unfamiliar panels and barriers as possible puzzle elements.
  • Save before engaging a major wild encounter or story battle.

The cave may include Zubat and Crobat encounters. If you want a Crobat, avoid knocking out every encounter automatically; weaken suitable Pokémon only when you are ready to capture them. Friendship-based evolution is also a possible long-term route for Zubat, but it requires consistent party use rather than a single item.

Cave Strategy

Flash improves awareness, but it does not reveal the correct puzzle solution automatically. Move one section at a time and revisit blocked branches after activating nearby mechanisms.

Cave Preparation Checklist:

  • Obtain the Coin Case from the sewer event
  • Purchase TM70 Flash for 1,000 Coins
  • Carry healing items and Poké Balls
  • Keep a compatible Pokémon available
  • Save before entering the research area

Flash, Encounters, and Progression Tips

Flash is primarily an exploration move, so choose its user based on convenience rather than battle role. If the Pokémon you want to use is already in your active party, teaching Flash can simplify the cave trip. If not, place a compatible utility Pokémon in your party temporarily and change your lineup after the exploration segment.

The surrounding progression may include story battles, hidden items, and optional detours. Avoid rushing directly to the objective if your team is already weakened. A short healing stop is usually more efficient than losing progress and repeating the route.

For Story Progress

Teach Flash to a convenient party member and focus on reaching the next objective.

For Collection

Carry Poké Balls, inspect side paths, and avoid defeating desirable Crobat encounters.

For Puzzle Safety

Save before experimenting with panels, vents, doors, or one-way ledges.

Team-Building Tip

Flash does not need to define your permanent team. Use a compatible utility Pokémon for the cave, then restore your preferred battle lineup afterward.

Flash is obtained as TM70 from the Chrisola Hotel Casino after completing the Coin Case event and collecting enough Casino Coins.

Q: How much does TM70 Flash cost?

The casino prize counter lists Flash for 1,000 Coins. Regular money is not the same as Casino Coins for this exchange.

Q: Why is Flash not available at the counter?

The most likely issue is that the Coin Case event has not been completed, or the required 1,000 Coins are not available.

Q: Do I need Flash to continue the cave story?

Flash makes the dark cave readable and supports the research route, but careful movement and puzzle awareness are still necessary after using it.
