Irreversible Choices & Permanent Decisions

Naming Your Buddy Pokémon: Once you nickname a Pokémon, you can change it anytime, so no irreversible decision here.

Evolving a Pokémon: Evolution is permanent. You cannot reverse it. Be certain you want that evolution, especially if the Pokémon has a Community Day move or is rare.

Using a TM (Technical Machine): Charged TMs and Fast TMs change one move randomly from the available pool. You cannot undo a TM usage. If you want a specific move, you may need multiple TMs.

Purifying a Shadow Pokémon: Purification costs Stardust and Candy and permanently removes the Shadow status. Shadow Pokémon have a 20% attack bonus but lower defense. Many high-level players keep Shadow Pokémon for raids and PvP. You cannot re-shadow a purified Pokémon. Think twice before purifying rare or meta-relevant Shadow Pokémon like Mewtwo, Metagross, or Dragonite.

Transferring a Pokémon: Transferring is semi-permanent. You can reclaim transferred Pokémon only if you have previously sent them to Pokémon HOME (via the GO Transporter) or if you contact Niantic support (rarely restores). Shiny, Legendary, or event Pokémon are especially valuable—never transfer them without checking stats, moves, and future usability.

Special Trades: Once you perform a Special Trade (shiny, legendary, or a Pokémon not yet in your Pokédex), that trade counts toward your daily limit. You cannot undo a trade.

Equipping a Buddy: Changing your buddy resets your current buddy’s progress toward that specific candy? No—candy progress is preserved. But if you swap buddies, you lose the current walking distance counter (it resets to 0 for that buddy). Plan ahead if you are close to earning a candy.

Missable Content & Time-Sensitive Events

Community Day: Exclusive moves, boosted shiny rates, and special field research. Moves can often be learned later via Elite TMs, but the chance to catch lots of one species is limited.

Special Research: Usually permanent but can be missed if you don’t log in during the event window to claim it. Some special research lines (e.g., “A Ripple in Time”) are permanently available after starting, but others like “Go Tour: Kanto” are limited.

Raids with Exclusive Pokémon: All Legendary and Mega Raids rotate. You cannot catch a specific Legendary outside its raid window unless it returns. Remote Raid Passes help but cost money.

Cosmetics & Avatars: Limited-time avatar items (hats, clothes, poses) are often one-off. If you miss an event, you may never get that item again.

Photobombs: During certain events, Smeargle or other Pokémon can photobomb your Snapshots. Miss the event window, lose the chance.

PokéStop Showcases: Limited-time competitions. If you don’t place your Pokémon during the showcase period, you can’t earn the rewards.

Meltan Mysterious Box: The only way to get Meltan is using Pokémon HOME to transfer a Pokémon to Let’s Go or to Sword/Shield. This opens a Mystery Box for 60 minutes. Missing the timer means you have to wait 3 days for the cooldown.

Difficulty Spikes

Gym Battles: Early on, you may face high-CP Blissey or Slaking. These are defense-heavy. Bring fighting types or Pokémon with high DPS. Teamwork makes it easier.

Raids: Tier 1-3 are soloable for most mid-level players. Tier 5 (Legendary) raids require at least 4-6 players with optimal counters. Mega Raids (Tier 5) also need groups. Use apps like Poké Genie or Go Friend to find raid groups.

Team GO Rocket Leaders: Sierra, Cliff, Arlo have strong Shadow Pokémon. The difficulty spikes at higher levels. You need super-effective counters and often shields management. Giovanni is even harder—you must complete a Super Rocket Radar quest line and prepare a specific team.

GO Battle League (PvP): Rank 20+ include Legendary Pokémon and skilled opponents. Master League requires level 40+ Pokémon with perfect IVs. Great and Ultra Leagues have CP caps, which are more accessible. Grinding for good IVs for PvP can be tedious.

Platinum Medals: Some medals, like “Fisherman” (catch 500 big Magikarp), “Pikachu Fan” (300 Pikachu), or “Guitarist” (catch 500 music-themed Pokémon) are very grindy and time-consuming.

Grinding Traps & Resource Management

Stardust: Most valuable resource. Do not waste it powering up low-IV, low-level Pokémon. Save for meta-relevant species with 80%+ IVs. Never spend on purified Pokémon unless they are top counters.

Candy: Rare species candy should be hoarded for legendaries. Do not waste Poffin to get candy from your buddy—Poffins are expensive.

Evolution Item Grind: Items like Up-Grade, King’s Rock, etc. are needed for certain evolutions. They drop from 7-day PokéStop streaks and sometimes from battling Team GO Rocket leaders. Don’t delete them accidentally.

Incubators: Free infinite incubator always used, but paid incubators are limited. Use them on 10km eggs (best for rare Pokémon and candy) or on 7km eggs (for regional forms). Don’t use premium incubators on 2km or 5km eggs unless you have too many.

Lucky Eggs: Use during 30-minute experience bonuses (e.g., friendship level-ups, evolving sprees). Do not pop one when casually catching.

Star Pieces: Use during Stardust events or when earning high Stardust from battles, raids, or eggs. Don’t waste on daily catches.

Rare Candy: Use only on Legendaries or Mythicals that you cannot walk for candy easily. Do not waste on common species.

TM Drought: Charged TMs are scarce. Only use when you desperately need a specific move (e.g., for a high-IV Pokémon). Consider waiting for Community Day or events when you can learn exclusive moves.

Friendship Leveling: Sending gifts daily and opening gifts (up to 20/day) yields huge XP at Ultra and Best Friend milestones. Use Lucky Eggs before those interactions. Coordinate with friends to open gifts at the same time.

Online Etiquette & Anti-Cheat Notes

Spoofing: Using fake GPS to catch Pokémon from home is against Terms of Service (ToS). Niantic detects and issues strikes: first warning (7-day ban), second strike (30-day ban), third strike (permanent suspension). Do not spoof—it ruins the game for others and risks your account.

Multi-Accounting: Using multiple accounts per player is also against ToS. Niantic can ban all accounts. Legitimate players may have two (e.g., one for each child), but don’t use them to hold gyms or spoof.

Botting: Automated gameplay is strictly forbidden and leads to permanent bans.

Share Your Friend Code Wisely: Posting your code on public forums can lead to spam. Use places like r/PokemonGoFriends for safe swapping.

Be Respectful at Gyms: Do not kick out every Pokémon right after someone places it—wait if possible. Don’t use multiple accounts to hold gyms longer than necessary. Some communities have gym ethics.

Remote Raid Etiquette: When joining a remote raid, do not leave at the last minute as it wastes others’ passes. Communicate via apps if you need to back out.

Event Cooperation: During Community Day or Raid Hours, respect private property, don’t block traffic, and be polite to others playing.

Save Management & Account Security

Google & Pokémon Trainer Club (PTC) Login: Your progress is tied to your login method. You can link multiple accounts (e.g., Google + Facebook) for redundancy. Do not delete your account without unlinking.

Cloud Save: Pokémon GO saves progress server-side. You cannot manually save or load local backups. If you lose your account, contact Niantic support with purchase receipts or screenshots.

Transferring to Pokémon HOME: This is a one-way transfer (except for Meltan box). Once sent, you cannot get that Pokémon back into GO. The GO Transporter has a limited energy bar that refills over time. Plan your transfers for valuable Pokémon.

Device Transfer: Unlinking a Google account incorrectly may cause data loss. Always unlink accounts via the game settings and then remove from device accounts.

Screenshots: Keep screenshots of high-value Pokémon, especially shinies with good IVs, as proof in case of account issues.

Things Players Commonly Regret Not Knowing Earlier

IVs Matter in Leagues: For Great and Ultra Leagues, a perfect 100% IV is often worse than a 0/15/15 spread for some Pokémon due to stat product. Use a PvP IV checker (e.g., Poke Genie, Calcy IV) before powering up—or keep low attack IV Pokémon.

Shadows vs Purified: Many new players purify for the CP boost or cost reduction. Shadow Pokémon have 20% more attack and are better for raids if powered up. Purified cost less but perform worse. Only purify if you want a hundo or need a purified type for certain research.

Stardust Hoarding: You’ll need hundreds of thousands to power up meta Pokémon. Start saving early.

Don’t Power Up Until Needed: Wait until you have a specific purpose (raid, PvP league) before spending dust and candy. A level 30 Pokémon is good enough for most PvE until you reach level 35+.

Catch Everything: Early on, catching everything gives XP, stardust, and possible luckies. Don’t ignore common spawns.

Eggs Are Random: No trick to control egg hatches. 10km eggs from PokéStops have different pools than 7km eggs from gifts. 7km eggs often hatch regional forms and babies—save them for events.

Friendship Bonuses: Friends who trade with you gain increased candy for distance trades. Trade with friends from far away (100+ km) for extra candy.

PokeCoins & Boxes: Spend coins only on Premium Battle Passes (for raids) or storage upgrades (Pokémon/Item). Avoid buying single Incense, Lucky Eggs, etc. Save for boxes that offer bundles.

Research Breakthroughs: The weekly legendary encounter is often not the best. Check if the current month’s legendary is worth chasing before aiming for it.

Nest Locations: Certain spawn points become nests for a species every two weeks. Use Silph Road nest atlas to farm candy and shinies.

Rename Pokémon with Stats: Many players rename using IV percentage (e.g., “98% 15/14/15”) or PvP rank to quickly identify keepers. This helps avoid accidentally transferring a gem.

Final Warnings

Data Usage & Battery: Pokémon GO uses GPS and data constantly. Use Wi-Fi when possible and consider a portable charger.

Safety: Always pay attention to your surroundings. Do not play while driving or crossing streets. Niantic warns: “Be aware of your environment at all times.”

In-App Purchases: It’s easy to overspend. Set monthly limits and avoid buying during event hype.

Account Recovery: If you lose access, Niantic support is slow. Link multiple accounts and keep proof of purchases.

By keeping these notes in mind, you’ll avoid many common frustrations and enjoy Pokémon GO more efficiently.
