You’re standing at a gym. It’s glowing with that ominous, swirling purple fire that signals a Pokemon Go shadow raid is about to kick off. You’ve got your Level 40 Mewtwo ready, your Revives are stocked, and you think you’re good to go. Then the raid starts. Your Pokemon are getting deleted in three hits. The boss is barely taking a scratch. Suddenly, the timer is at thirty seconds and you’ve barely made a dent.
Shadow raids are a different beast entirely.
Niantic introduced these as a way to spice up the gym scene, but honestly, they’re some of the most frustrating content in the game if you don't know the mechanics. Unlike your standard Tier 5 raids where you can usually coast with a decent group, shadow raids introduce the "Enraged" mechanic. This makes the boss’s Attack and Defense skyrocket mid-match. If you aren't using Purified Gems, you’re basically throwing your Raid Passes into a woodchipper. It’s brutal. It’s fast. It’s arguably the most "hardcore" thing Pokemon Go has right now outside of high-rank GBL.
The Enraged Mechanic: The Part Everyone Forgets
The biggest hurdle in any Pokemon Go shadow raid is the Enraged state. Usually, once the boss hits about 60% to 70% health, it starts glowing. That’s when the math changes. Their damage output jumps and they become significantly tankier.
You need Purified Gems.
These are crafted from Shadow Shards, which you get by beating Team GO Rocket grunts or leaders. You need five shards to make one gem. When the boss is Enraged, you tap that little gem icon on the bottom left of your screen. If your team uses eight gems collectively, the boss is subdued. It loses that massive buff and goes back to being a "normal" raid boss for a bit. If you’re soloing a Tier 3 shadow raid, you can use up to five gems yourself, which is usually enough to break the Enrage if you’ve got the DPS. But for Tier 5? You need a coordinated group. You can't just spam taps and hope for the best. Communication is actually required here, which is kinda rare for this game.
Real Talk on Shadow Mewtwo and the Legendary Rotation
Let’s look at the heavy hitters. Shadow Mewtwo is widely considered the holy grail of Pokemon Go shadow raid encounters. Why? Because a Shadow Mewtwo with a 0 IV (Individual Value) floor still outclasses a 100% IV (Hundo) regular Mewtwo in terms of raw damage. The 20% shadow attack bonus is just that broken.
When these legendary shadow raids rotate in during special weekend events, the meta shifts. You’ll see players traveling to high-density city centers because, remember, you cannot use Remote Raid Passes for shadow raids. This is the big "gotcha." Niantic wants people walking. They want people meeting up. If you live in a rural area, shadow raids are basically a giant "keep out" sign unless you can convince a few friends to drive out to a park with you. It’s a point of contention in the community, honestly. Some people love the "old school" feel of local-only raiding, while others think it’s a gatekeeping nightmare.
Why Your "Great" Team Is Getting Wrecked
The math behind shadow raids is punishing. Because the boss deals more damage, your glass cannons—think Gengar or Breloom—are almost useless. They die before they can even fire off a Charged Attack.
- Survivability is king. You need Pokemon that can tank a hit while the Enraged mechanic is active.
- The Shadow Bonus works both ways. You deal 20% more damage, but you take 20% more.
- Typing matters more than CP. A 2500 CP Pokemon with a type advantage is almost always better than a 4000 CP Slaking that’s just sitting there soaking up energy without dealing effective damage.
Most players make the mistake of not dodging. In a standard raid, dodging is often a waste of time—you want to maximize DPS. In a Pokemon Go shadow raid, missing a dodge on a move like Hydro Pump or Earthquake can mean your entire lineup is gone in ninety seconds. You have to watch the yellow flash. You have to move.
Navigating the Purified Gem Economy
Managing your Shadow Shards is a game within a game. You can only hold ten Purified Gems at a time. This is a weirdly low cap. If you’re planning a heavy raid day—maybe during a Shadow Entei or Suicune weekend—you’ll hit that cap fast.

You should be battling every Rocket Grunt you see in the days leading up to a big shadow event. Don't just ignore the "useless" Grunts like the ones with Rattata or Zubat. You need those shards. Also, keep an eye on your inventory space. Shards don't take up bag space, but the Gems do. It's a small detail, but it’s annoying when you try to claim a Gem and your bag is full of Nanab Berries you forgot to toss.
The Solo Tier 3 Strategy
Tier 3 shadow raids are the sweet spot for many solo players. Pokemon like Shadow Machamp or Shadow Alolan Marowak are soloable, but you have to be precise.
First, check the weather. If it’s Cloudy and you’re fighting a Shadow Machamp, its Fighting-type moves are boosted. You’ll get shredded. Wait for Windy weather to boost your Psychics or Fairies. Second, don't use your gems immediately. Wait for the Enrage. If you use them too early, you've wasted resources. If you wait too long, you’ve lost too much time and your Pokemon are fainted. It's about finding that rhythm.
I’ve seen people lose a Shadow Machamp raid with a team of Level 50 Rayquazas just because they ignored the Enrage mechanic and didn't use gems. It’s a humbling experience.
Is Purifying Actually Worth It?
This is the age-old question. After you win a Pokemon Go shadow raid, you get the chance to catch the Shadow Pokemon. It’ll have a minimum IV floor (usually 6/6/6), which is better than the 0/0/0 you might get from a Grunt.
Should you purify it?
Usually, no. The 20% damage boost is too valuable for raids. However, there are exceptions. If purifying it gives you a 100% IV Pokemon and that specific species has a Mega Evolution—like Swampert or Tyranitar—it might be worth it. A Mega Evolution is often better than a Shadow, and you can't have both at the same time on one Pokemon. Also, if you’re a heavy PvP player in the Master League, sometimes the bulk of a Purified Pokemon is better than the fragility of a Shadow. But for strictly raiding? Keep 'em dark. Keep 'em angry.
Practical Steps for Your Next Shadow Raid
Success in these encounters isn't just about tapping the screen until your finger hurts. You need a checklist.
1. Stockpile your Shards early. Don't wait until the legendary egg spawns to realize you have zero Purified Gems. You need at least 8 gems available across your group to instantly subdue a Tier 5 boss.
2. Scout the moveset. Use the "recommended" team as a hint. If the game is recommending a bunch of Aggrons, the boss probably has a move that hits your usual attackers for super-effective damage. Take thirty seconds to actually look at what you’re bringing.
3. Coordination is the only way. If you’re raiding with strangers, literally talk to them. Ask, "Who's using gems?" If everyone uses them at once, you break the Enrage faster. If nobody uses them, you’re going to fail. It's that simple.
4. Focus on the catch. Shadow Pokemon are notorious for being aggressive in the catch screen. They jump and attack way more than regular raid bosses. Use your Nanab berries if you’re struggling, but ideally, learn the "circle lock" trick. Wait for the attack animation to finish, then throw. Don't get impatient and waste your Premier Balls.
5. Check your local community maps. Since these are local-only, tools like Campfire are essential. Use the map to find where people are gathering. If you see a flare at a gym, get over there. You aren't winning a Shadow Lugia alone.
The meta for the Pokemon Go shadow raid continues to evolve as Niantic tinkers with the boss pool. Stay flexible, keep your gems maxed out, and stop purifying your high-IV shadows just for the "pretty" stars. The extra power is what wins raids.
