How to get it
- Earn it from an event reward track that explicitly includes this cap. Past releases have used paid GO Pass Deluxe tracks.
- These are not routine PokéStop, raid, or Gift drops.
How to use it
- Choose an eligible Pokémon with at least Good Buddy friendship, select the target stats, and complete its Hyper Training tasks.
- Shadow Pokémon are ineligible. Check both the cap’s activation deadline and the training deadline shown in game.
Worth knowing
Increasing IVs can raise CP and change eligibility or performance in CP-limited leagues. Evaluate the intended build before training.
A Gold Bottle Cap can train multiple stats in one course; a Silver Bottle Cap is useful when only one stat needs work.
Two different deadlines
The unused cap can expire on an event-specific date. Starting Hyper Training begins a separate 365-day task window. Having a year to train does not mean you have a year to activate an unused cap.
Why higher IVs are not always a better league build
IVs contribute to both battle stats and CP. Under a league’s CP ceiling, an increase can force a Pokémon to stay at a lower level than another individual of the same species. That is why a perfect appraisal is not a universal target for Great League or Ultra League.
Compare a Great League Golem with 15/15/15 IVs at level 17.5 against a 12/15/15 Golem at level 18. In that example, the lower-Attack-IV individual has slightly higher effective Attack as well as better Defense and HP. The comparison is between two builds, not a way to lower IVs with a cap.
For a Pokémon intended for a CP-limited league, check its final CP, level, and role before selecting the training target. For a species that stays below the limit even when fully powered up, maximizing IVs can make much more sense.
Training progresses one point at a time
Keep the trainee as your buddy while completing its tasks. Each completed task increases the relevant IV by one point, and only one task per stat can progress at once. A completed increase cannot be reversed.
The current Help Center also excludes already-perfect Pokémon and says Hyper Trained Pokémon cannot be sent to Pokémon HOME. Check these consequences before committing a collectible you may want to transfer later.
