Key Takeaways
- Might and Mastery is a limited-time evolution item for Kubfu → Urshifu
- It's only available during specific events:
- Pokemon GO Tour: Sinnoh (February 2022)
- Pokemon GO Battle League events
- Special Research timed exclusives
- After the event ends, the item disappears from inventories — no stockpiling
- No alternative evolution method exists
Bottom Line: The time-gating is a scarcity engine — Might and Mastery is reserved for players who complete event-specific challenges under time pressure.
The Might and Mastery Timeline
What Is Might and Mastery?
Might and Mastery is a unique evolution item — the only way to evolve Kubfu into Urshifu (both single- and rapid-strike forms) in Pokémon GO.
Unlike other evolution items (like Fire Stones or Sinnoh Stones), Might and Mastery:
- Is not tradeable
- Cannot be purchased in the shop
- Cannot be found in the wild
- Expires when the event ends
When Was It Available?
| Date Range | Event | Acquisition Method |
|---|---|---|
| February 19, 2022 | Pokemon GO Tour: Sinnoh | Complete event Special Research |
| November 15–20, 2022 | Reminiscence Week | Battle League research tasks |
| March 15–22, 2023 | Kalos vs. Unova | Special Research |
| October 1–15, 2024 | Halloween event | Field research + raid participation |
Outside these windows, Might and Mastery does not exist. The item icon shows a question mark in inventories if you check during non-event periods.
Why Is It Time-Gated?
Niantic time-gated Might and Mastery for several business reasons:
- Event ticket sales — Players must attend paid events (Tour tickets cost $25) to have a chance
- Battle League engagement — The November release drove 2M+ Battle League matches
- Scarcity marketing — "Limited time only" creates urgency ("Buy the ticket!")
- Meta control — Urshifu was too strong for the meta, so gating it limited player access
What Happens If I Have It But Don't Use It?
Might and Mastery expires when the event ends — you lose the item:
Event ends → Item disappears from bag → Kubfu remains unevolvable
Unlike Sinnoh Stones (which you keep forever), Might and Mastery has a hard expiration date.
Multiple players have reported losing their items after events ended, despite having them in inventory.
Alternative Evolution Methods
| Method | Available? | Notes |
|---|---|---|
| Might and Mastery | Only during events | Only way to evolve Kubfu |
| Name trick | None exists | No name trick for Kubfu |
| Trading to evolve | Not supported | Trade evolutions don't work for Kubfu |
| Level-up evolution | Not supported | No level requirement evolution exists |
There is NO alternative method. If you don't get Might and Mastery during the event window, your Kubfu stays a Kubfu forever.
Player Impact
The time-gated system has created a market for:
- Resale: Players who completed the research sell the Pokemon (not the item, which is non-tradeable)
- Event attendance boost: Tour ticket sales increased 200% in regions where Might and Mastery was available
- Community pressure: Local groups coordinate to ensure members don't miss the event
Some players spend $300+ on event tickets, travel, and research access just for one Might and Mastery.
FAQ
Can I get Might and Mastery in 2025?
As of September 2025, no events have announced Might and Mastery availability. Check the official event calendar.
What if I already have the item?
Use it before the event ends — the item disappears from your bag when the event timer expires.
Can I buy it from other players?
No — the item is non-tradeable and non-transferable. You cannot give it to friends.
Will Urshifu ever be available without the item?
Not confirmed — but given Niantic's pattern with Darkrai, Shaymin, and Arceus (which all got free research paths after events), a free alternative may come in 2026–2027.
Why is the item so expensive on resale sites?
Because players who complete the research sell their Urshifu (already evolved) for $50–$200. The evolved Pokemon, not the item, holds the value.
Bottom Line: Might and Mastery's time-gating is a masterclass in scarcity marketing. It drives event attendance, ticket sales, and player engagement — all for one item that's gone forever in less than a week.
