Should I Keep The Thunderstone Kcd2?

When It Makes Sense

• Good fit: If you are targeting a late‑game evolution that requires a Thunderstone—such as evolving a Pikachu into Raichu after you have already completed most of the main storyline—keeping the item ensures you won’t have to backtrack for another one.
• Good fit: When you are playing a challenge run that limits item usage, retaining a single Thunderstone can serve as a strategic reserve for a critical moment, allowing you to trigger an evolution that provides a needed stat boost.

When You Should Avoid It

• Warning sign: If you already possess multiple Thunderstones or have access to a reliable source (e.g., a vendor or in‑game event) that can replenish them, keeping an extra one adds little value and occupies inventory space.
• Warning sign: In a speed‑run or time‑sensitive playthrough where every inventory slot matters, holding onto a Thunderstone that you do not plan to use soon may slow progress.

Pros and Cons

Pros

• Guarantees you can evolve a Thunderstone‑dependent Pokémon at the exact moment you need its upgraded abilities.
• Provides flexibility in builds, especially for players who like to experiment with different evolution timings.

Cons

• Consumes inventory space that could be used for consumables, loot, or other rarer items.
• If the Thunderstone is abundant in the game world, keeping one may be redundant and wasteful.

Decision Checklist

• Do I have a clear need for a Thunderstone later in the game (specific evolution or stat boost)?
• Is the Thunderstone scarce or easy to obtain again?
• Will holding the item limit my ability to carry more essential resources?

Alternatives to Consider

Instead of keeping the Thunderstone, you could trade it to a NPC for a different rare item, sell it for in‑game currency, or use it immediately on a Pokémon that benefits from an early evolution. If you are unsure about future needs, maintaining a diversified inventory of evolution stones (e.g., Fire Stone, Water Stone) can provide broader options.

Final Recommendation

If you anticipate a specific, valuable Thunderstone evolution later and the item is hard to reacquire, keeping it is sensible. In most other cases—especially when the stone is plentiful or inventory space is at a premium—trading, selling, or using it promptly is the safer route. As always, tailor the decision to your playstyle and consider consulting community guides for high‑level strategy.
