The gym has gone dark — flat black on the map, with a purple flame flickering over the raid egg. You know what that means. But here’s the thing most players discover too late: walking into a 5-star Shadow Raid without Purified Gems is like showing up to a tank fight with a slingshot. The boss enrages at 60% HP, its defence triples, and your team chips away at a near-impenetrable wall until the timer runs out.
Shadow Raids play by rules that standard raids don’t. This guide covers all of them — what makes Shadow Raids distinct, how the enrage mechanic actually works (including the stat maths behind it), how to build a Purified Gem supply from scratch, and concrete strategies for clearing every tier, including 5-star fights that demand real group coordination.
If you haven’t done standard raids before, the Pokémon GO raid guide covers the basics of tiers, counters, and Premier Balls before you tackle the shadow variant.
What Are Shadow Raids?
Shadow Raids are a special raid type where the boss is a Shadow Pokémon — a corrupted Pokémon under Team GO Rocket’s control. Introduced in May 2023 as part of the Rising Shadows event, they now appear regularly at gyms that Team GO Rocket has taken over.
Two visual tells identify them on the map:
- The raid egg has a purple flame behind it
- Once the egg hatches, the gym turns black on the map
The most important rule first: Shadow Raids are in-person only. Remote Raid Passes cannot be used. There’s no remote join system, no friend invites for distant players. If you want a Shadow Legendary, you’re heading to a gym [1].
Shadow Raids run across three tiers on different schedules:
| Tier | Schedule | What’s Available |
|---|---|---|
| 1-Star | Daily | Shadow common Pokémon — easy solo |
| 3-Star | Daily | Shadow mid-tier Pokémon — soloable with strong counters |
| 5-Star | Weekends only (Sat–Sun) | Shadow Legendary Pokémon — group required |
Five-star Shadow Raids are the main prize — the only way to catch Shadow Legendary Pokémon and the only source of Shiny Shadow Legendaries in the game. Giovanni encounters cannot produce shiny Legendaries. Shadow Raids can [2].
The Enrage Mechanic: Why Shadow Raids Are Different
This is the single mechanic that separates Shadow Raids from every other raid content in the game, and it’s the reason preparation matters so much.
When the boss loses 40% of its HP — hitting the 60% threshold — it enters Enrage mode. A pulsing purple aura intensifies around the boss and its combat stats shift dramatically [3]:
- Attack: approximately 1.81× base attack, plus 15 flat
- Defence: approximately 3× base defence, plus 15 flat
The attack boost is noticeable — incoming damage spikes and your Pokémon start fainting faster. But the defence boost is the real obstacle, and most guides gloss over how severe it is. At 3× defence, your counters are dealing roughly a third of their normal DPS. A boss that would fall in 30 seconds now takes 90+ seconds to shift. On a 5-star boss with 15,000 HP, that means fighting through 6,750 HP of tank-mode combat — from 60% down to the natural-subdue threshold at 15% — with sharply reduced damage output the entire way.
Without Purified Gems, that 45% HP window is close to impossible to clear with a small group. The maths simply don’t work against a 3× defence wall on a countdown timer.
Natural subdue: If your group somehow pushes the boss to 15% HP while it’s still enraged, it automatically returns to normal stats. In 5-star raids, almost no group gets there without gems — but it does happen in large enough groups where raw DPS overwhelms the mechanic entirely.
Purified Gems: How to Farm and Use Them
Purified Gems are the direct counter to enrage. Throw one at the boss during the raid and it takes a debuff step toward Subdue — reverting toward its normal, non-enraged stats. Eight gems across the group force a full Subdue.
Step 1 — Farm Shadow Shards
Purified Gems are crafted from Shadow Shards. Shards drop from every Team GO Rocket encounter [4]:
| Source | Shards Dropped |
|---|---|
| Rocket Grunt (PokéStop takeover) | 1 shard |
| Rocket Leader (Arlo, Cliff, Sierra) | 3 shards |
| Giovanni | 4 shards |
| Shadow Raid victory (1-star) | 1 shard base |
| Shadow Raid victory (3-star or 5-star) | 3 shards base + possible bonus drops |
The fastest shard farm outside of raids is fighting Rocket Leaders — 3 shards per battle, no raid pass needed. If you have an active Rocket Radar, working through Leader battles between Shadow Raid weekends is the most efficient gem pipeline available.
Step 2 — Craft Gems Automatically
Four Shadow Shards automatically combine into one Purified Gem through the Shard Refiner — no manual crafting action needed. The refiner activates as soon as your count hits four [4].
Your inventory cap is 10 Purified Gems. The goal before any 5-star Shadow Raid weekend: farm up to 10 gems, so you arrive at the gym fully loaded across multiple fights.
Step 3 — Use Gems During the Raid
When the boss hits 60% HP and enrages, a gem button appears at the bottom-left of your battle screen. Tap it to throw a Purified Gem. The rules for gem use [3]:
- 5-second cooldown between throws — you can’t rapid-fire them
- Maximum 5 gems per player per raid — regardless of how many you’re carrying
- 8 gems total across all trainers triggers full Subdue, returning the boss to non-enraged stats
Because one trainer can only throw 5 gems and 8 are required, a single player can never fully subdue a Shadow Raid boss. You need at least two trainers for the gem system to reach its ceiling — this is by design.
Three-Star Shadow Raids: Strategy
Three-star Shadow Raids are accessible, and the enrage mechanic is far less punishing at this tier. The boss has only 3,600 HP — so at 60%, the enraged window covers just 2,160 HP. With strong type counters, a duo can often blast through that window before gems are needed.
Can you solo 3-star Shadow Raids? Yes — with max-level, type-effective counters. It’s tighter than a standard 3-star because the Shadow boss deals 20% more damage, but solo is achievable for experienced players with the right team.
Should you use Purified Gems in 3-star? Optional — save them for 5-stars. One or two gems ease the fight significantly if you’re solo or under-powered, but a well-matched duo can skip gems entirely and clear in the enraged window without issue.
Counter strategy: Identify the boss type, bring your highest-DPS counters for that weakness, and lean on Shadow versions of top attackers where available. For building your Shadow attacker roster, the Shadow Pokémon guide covers the top Shadow attackers by type — the same Pokémon that dominate standard raids are your best tools in Shadow Raids.
Current 3-star Shadow bosses (March 2026): Shadow Alolan Marowak, Shadow Lapras, Shadow Stantler [2].
Five-Star Shadow Raids: Strategy
Five-star Shadow Raids are the hardest in-person content in Pokémon GO. A 15,000 HP boss, the enrage defence wall, and the in-person-only restriction combine to make these a genuine group challenge — not just a numbers game.
How Many Players Do You Need?
| Group Size | Viability |
|---|---|
| 2–3 trainers | Very difficult — requires max-level Shadow counters and perfect gem coordination |
| 4–5 trainers | Solid — manageable with good counters and active gem use |
| 6–8 trainers | Comfortable — standard clear for most groups |
| 9+ trainers | Easy — raw DPS can overwhelm even the enraged phase without gems |
The sweet spot for most community groups is 5–6 trainers. Enough to share the gem load and absorb the enrage phase, without over-relying on any single player’s contribution.
Gem Coordination: Two Strategies
Every trainer should arrive with 5 Purified Gems — the per-raid maximum. You need 8 gems across the group to force full Subdue [3].
Strategy 1 — Stagger throws: One player uses a gem, waits 5 seconds (the cooldown window), the next player throws, and so on in sequence. Staggering chains the subdue effect across a longer total window, keeping the boss debuffed while the group pours in DPS. Best when you can communicate via Discord or in-person call-outs.
Strategy 2 — Simultaneous burst: Multiple players throw gems at once for an immediate, sharp subdue. Simpler to coordinate on the fly — “everyone throw now!” — but less efficient in total subdued duration compared to staggering.
For most in-person groups, stagger wins when you can communicate. If your group is scattered and coordination is chaotic, the simultaneous burst is easier to pull off and still gets the job done with enough players.
Current 5-Star Boss: Shadow Latias (March 2026)
Shadow Latias is Dragon/Psychic type. Her weaknesses are Ice, Dragon, Ghost, Bug, Fairy, and Dark [5].
| Pokémon | Type | Best Moves |
|---|---|---|
| Shadow Salamence | Dragon/Flying | Dragon Tail + Outrage |
| Shadow Dragonite | Dragon/Flying | Dragon Tail + Outrage |
| Shadow Garchomp | Dragon/Ground | Dragon Tail + Outrage |
| Shadow Weavile | Dark/Ice | Snarl + Avalanche |
| Zacian (Hero form) | Fairy/Steel | Snarl + Play Rough |
| Shadow Gengar | Ghost/Poison | Shadow Claw + Shadow Ball |
| Togekiss | Fairy/Flying | Charm + Dazzling Gleam |
| Shadow Mamoswine | Ice/Ground | Powder Snow + Avalanche |
Weather tip: Fog boosts Ghost and Dark moves — a natural advantage for Shadow Gengar and Shadow Weavile. Snow boosts Ice, helping Shadow Mamoswine. Windy weather boosts both Dragon-type counters and Latias’s Psychic/Dragon attacks — a double-edged boost. For the full type-to-weather mapping and how to plan around it, the weather boost guide covers every combination [6].
Shadow Attackers: Your Best Counter Option
The Shadow combat bonus applies in raids just as it does in gyms and PvP — and in a DPS race against a timer, that 20% attack edge is the most reliable advantage you can bring.
Shadow Pokémon deal 20% more damage and take approximately 20% more damage compared to standard equivalents [7]. In raids, the extra offence almost always wins. A faster boss kill means fewer faint cycles and more Premier Balls. The added fragility matters less when the fight ends sooner.
The attack bonus stacks multiplicatively with STAB and type effectiveness. Shadow Weavile using Snarl into Avalanche against Latias — Ice is 2× effective against Dragon, Weavile gets STAB on Ice, plus the Shadow multiplier: roughly 2.3× base damage output. That’s the kind of multiplier that pushes through enraged phases fast.
If you’re raiding with your regular group, levelling up friendship adds a further attack bonus that stacks on top of everything else. Ultra Friend gives 1.05× and Best Friend gives 1.1× — worth maximising for anyone you raid with weekly.
Counter-building framework for any Shadow Raid boss:
- Identify the boss’s type weaknesses
- Select top-DPS Pokémon for each weakness — Shadow version first
- Lead with a Mega Pokémon of the relevant type if you have one, for the group damage bonus
- Check the weather and align your counter type with active boosts where possible
Rewards: What You Get
Premier Balls
Premier Balls are awarded after a Shadow Raid victory based on damage dealt, battle accolades (Ace Raider, Rival Felled, etc.), and Rocket Grunt bonus. One key difference from standard raids: Shadow Raids do not award the gym team control bonus that standard raids give. You can’t top up your ball count by holding the gym beforehand [1].
The Catch Encounter
The boss appears as a Shadow Pokémon in the catch encounter — not a standard or purified form. Key differences from standard raid catches [3]:
| Stat | Standard Raid Catch | Shadow Raid Catch |
|---|---|---|
| IV floor | 10/10/10 | 6/6/6 |
| Shiny possible? | Yes | Yes |
| Form | Standard | Shadow |
| Mega Eligible? | Yes | No (unless purified) |
The lower IV floor (6/6/6 vs 10/10/10) means Shadow Raid catches can have worse individual stats. For Shadow Legendaries, this rarely matters in practice — the 20% attack bonus in raids more than compensates for a lower-IV catch in most DPS scenarios. If you’re chasing a specific PvP IV spread, though, you’ll need more attempts.
Shiny Shadow Legendaries: Shadow Raids are the only source. Giovanni encounters do not yield Shiny Legendaries. If Shiny Shadow Latias — or any future Shadow Legendary — is on your target list, the 5-star Shadow Raid during its active rotation is your only window [5].
Shadow Shards and Other Loot
Shadow Raids drop Shadow Shards where standard raids would drop Fast TMs and Charged TMs:
- 1-star victories: 1 Shadow Shard base
- 3-star and 5-star victories: 3 Shadow Shards base, with possible bonus bundles
The loop is intentional design — Shadow Raids feed their own gem supply. The more you run, the more Shards you accumulate for next weekend’s 5-star. You also receive standard raid loot: Rare Candy, Golden Razz Berries, and XP.
Can You Solo Shadow Raids?
| Tier | Solo Possible? | Notes |
|---|---|---|
| 1-Star | Yes | Straightforward — bring appropriate type counters |
| 3-Star | Yes (with effort) | Max-level Shadow counters recommended; gems optional |
| 5-Star | No | 8 gems to subdue require 2+ trainers; boss HP too high for 1 trainer |
The 5-star no-solo rule is mechanical, not just a difficulty setting. You can bring 5 gems and throw all of them — but 5 is less than 8, so the boss never reaches full Subdue. An un-subdued Shadow Legendary sitting at 3× defence for 45% of its HP bar is close to unkillable before the timer runs out. You need at least one other trainer to hit that 8-gem ceiling.
Frequently Asked Questions
Can you use a Remote Raid Pass for Shadow Raids?
No — Shadow Raids are in-person only. Remote Raid Passes don’t work and there’s no remote invite system for Shadow Raids [1].
How many Purified Gems does it take to fully subdue the boss?
Eight gems thrown across all participating trainers. One player can throw a maximum of 5, so you need at least two trainers to hit the 8-gem subdue threshold [3].
What’s the maximum Purified Gems I can carry?
Ten. You can only use 5 per raid, so a full inventory gives you two fights’ worth of gems on a Shadow Raid weekend.
When do 5-star Shadow Raids appear?
Weekends only — Saturdays and Sundays — unless a special event changes the schedule. One-star and 3-star Shadow Raids run daily.
What’s the IV floor for Shadow Raid catches?
6/6/6 — lower than the standard raid floor of 10/10/10. Each stat rolls between 6 and 15.
Do Shiny Shadow Pokémon exist?
Yes. Shadow Raids are the only source of Shiny Shadow Legendaries — Giovanni encounters never produce shiny Legendaries. The rate during featured Shadow Raid periods is approximately 1 in 64 [5].
Are Shadow Raids worth doing if I’m not chasing Legendaries?
Yes. Three-star and 1-star Shadow Raids are your primary source of Shadow Shards outside of Rocket battles, feeding your gem stockpile for 5-star weekends. They also offer Shadow Pokémon that aren’t always available through Grunt and Leader encounters.
Conclusion
Shadow Raids are one of the few pieces of Pokémon GO content deliberately designed for in-person group play. The no-remote rule, the 8-gem coordination floor for 5-stars, and the weekend-only schedule for Shadow Legendaries all push you toward gathering at a gym with a group — which is exactly when this game feels most like itself.
The mechanic isn’t complicated once you understand it: the 3× defence wall is the real obstacle, and 8 Purified Gems are the key. Farm Shadow Shards from Rocket Leaders all week, arrive on the weekend with a full gem inventory, stagger your throws when the boss hits 60%, and push DPS hard in the Subdued window.
Shadow Legendaries are the highest-DPS versions of themselves in the game — and a Shiny Shadow version is a trophy you can only earn by being there. That’s worth the in-person coordination.
