After claiming the Royal League title, the real test begins. Gym Mastery opens up a new rematch ladder where every one of the 13 leaders you beat on the way up returns — sharper, smarter, and ready to actually test you.
What is Gym Mastery?
Gym Mastery unlocks the moment you defeat Champion Leon for the first time. Every gym leader in the Zenith Region and every Royal League member is now available for rematch battles across three tiers of increasing difficulty: Easy, Medium, and Hard.
The level cap for each leader stays exactly the same as your first encounter — this isn't about grinding levels. It's about teambuilding, itemization, and out-thinking a tournament-grade AI within the caps you already know. Easy feels like a slightly tighter version of the original fight. Hard is a different sport.
How to access
Just talk to any gym leader in Zenith or any Royal League member in the Royal Hall once you've beaten Champion Leon. A new dialogue option will appear alongside the original gym challenge, letting you pick your rematch tier.
You can also accept the corresponding Journey tasks — one pair per region per tier — which track your progress and hand out rewards on completion:
Zenith Mastery: Easy / Medium / Hard— all 8 Zenith leadersRoyal Mastery: Easy / Medium / Hard— all 5 Royal League members
The three tiers
| Tier | Team size | Investment | Held items | Gimmicks |
|---|---|---|---|---|
| Easy | 4 Pokémon | Light EV spread | Basic utility | None |
| Medium | 5 Pokémon | Proper EVs (128 in two stats) | Competitive staples | None |
| Hard | 6 Pokémon | Full tournament spread (252/252) | Mega Stones, type-boosting items, Tera setup | Mega Evolution or Terastallization on the ace |
Each tier is the same species chart you remember, built sharper. Easy is your Gen 1 tutorial flashback. Medium runs proper competitive sets. Hard is the version the leader would bring to a World Championship.
Tier gating
Per leader, sequential: You have to beat a leader on Easy before Medium unlocks, and Medium before Hard. No skipping.
Across regions, parallel: Zenith mastery and Royal mastery progress independently. You can work through Zenith Easy and Zenith Medium without ever touching the Royal League rematches, or vice versa.
The Journey quests follow the same rule — Zenith Mastery: Medium won't start until you've completed Zenith Mastery: Easy, but you can grind Royal Easy at the same time.
Hard tier gimmicks
At Hard tier, every leader's ace Pokémon pulls out a gimmick when the team starts running thin. Expect the animation, the stat boost, the type shift, and a much less forgiving matchup.
| Leader | Ace | Gimmick |
|---|---|---|
| Roark (Zenith 1) | Houndoom | Mega Evolution |
| Vivienne (Zenith 2) | Beedrill | Mega Evolution |
| Iceland (Zenith 3) | Mamoswine | Terastallization |
| Marina (Zenith 4) | Wigglytuff | Terastallization |
| Sage Verity (Zenith 5) | Gardevoir | Mega Evolution |
| Marcus (Zenith 6) | Drapion | Terastallization |
| Cole (Zenith 7) | Mawile | Mega Evolution |
| Iris (Zenith 8) | Garchomp | Mega Evolution |
| Flora (Royal 1) | Gardevoir | Mega Evolution |
| Inferno (Royal 2) | Gengar | Mega Evolution (Chandelure backup Tera) |
| Tidecaller (Royal 3) | Garchomp | Mega Evolution (Kingdra backup Tera) |
| Sentinel (Royal 4) | Metagross | Mega Evolution (Aegislash backup Tera) |
| Champion Leon | Charizard | Mega Evolution Y (Dragapult backup Tera) |
The ace gimmicks when its team is down to its final few — don't expect an easy opening if you stall. Plan to burst the ace before it transforms, or bring answers for the post-gimmick form.
The Hard Gauntlet (Royal League only)
The Royal League's Hard tier works differently. Instead of five independent rematches, Hard Flora → Hard Inferno → Hard Tidecaller → Hard Sentinel → Hard Champion Leon form a single sequential gauntlet.
- Win all 5 in a row to clear the gauntlet and unlock the capstone reward.
- Lose any match and all 5 Hard-tier flags reset. You'll have to run the gauntlet again from Flora.
Your Easy and Medium clears are preserved — only the Hard-tier progress is wiped on a failed run. Your League Points aren't touched either. This is a rematch ladder, not a badge run — no rank is at stake.
Come prepared. Heal between fights. Bring a team that covers all 5 members.
Rewards
Each tier pays out in flavor, not just numbers:
- Easy — Pokédollars, Bottle Caps, and a lore-flavored TM from that leader's specialty
- Medium — Pokédollars, Ability Capsules, EV-reducing berries (Pomeg, Kelpsy, Qualot, Hondew, Grepa, Tamato), and a strategic setup TM
- Hard — Pokédollars, Ability Patches, Tera Shards matching the leader's type, and a top-shelf TM
Capstones stack extras on top: Gold Bottle Caps, Master Balls, a Charizardite Y for mastering Zenith Hard, and a Choice Specs ("Champion's Choice") for clearing the Royal Hard Gauntlet.
A full clear of all 6 Journey tasks pays out roughly ₽552,500, 4 Master Balls, 16 Ability Patches, 16 Ability Capsules, 65 Tera Shards across 13 types, 31 Bottle Caps, 3 Gold Bottle Caps, and 39 TMs. Don't min-max it — the real reward is the matchup.
Tips
- Stay within the cap. Your whole party is auto-capped at the leader's level. Over-leveled Pokémon can't challenge — the cap guard refuses the fight.
- Practice at Easy first. Don't skip straight to Medium. Easy is tuned so you can feel out each leader's new movesets and gimmick ace without burning resources.
- Medium is the teambuilding tier. This is where a thrown-together 4-mon party stops working. Proper EVs and item choices matter from here on.
- Hard asks for specialization. Expect to build a team for each leader. One generalist squad won't carry you through 13 tournament sets.
- The Royal Hard Gauntlet rewards patience. Five back-to-back matches with no heal between them (aside from your own potions/berries). Don't start the run unless you're rested and stocked.
Good luck, Champion. This is what you trained for.
