Pokémon Go Field Research was a major addition for the game in 2018, introducing new Pokémon Go tasks for players to accomplish.
Completing Pokémon Field Research tasks also provides unique rewards as part of Research Breakthroughs, while Special Research taskschance to uncover never before seen Pokémon, including the elusive Mythical Pokémon Mew.
For a limited time, there are also Detective Pikachu Research tasks and rewards, which we detail below in full, too.
Field research tasks and rewards change every month, but now there are plenty of additions to that monthly cycle, with many special events and limited features getting their own Research quests as well.
Pokémon Go Detective Pikachu event research task rewards, including Seed Pokémon, Backpack Pokémon riddle solutions
The Detective Pikachu Event is live in Pokémon Go from May 9th, and brings several new wild spawns, raid encounters, a new photobomb to catch, avatar items and new limited-time research tasks and rewards, too.
The Detective Pikachu research tasks are available until the usual reset time of 9pm UK / 1pm PDT on Friday, May 17th, although tasks can be completed and rewards can be claimed at any point after that if you've picked up the task before the event ends and keep hold of it.
Pokémon Go May Field Research tasks and Research Breakthrough rewards
The May Field Research in Pokémon Go is the same as both January, February and March - and has the Research Breakthrough reward of various Legendary Pokémon from previous appearances in Field Research throughout the year.
Those May and June Research Breakthrough reward Pokémon are: Ho-Oh, Lugia, Latios and Latias. Usually, the rewards from PokéStops are based on the reward Pokémon's Type, but with so many available, there's no fixed Type for now.
Pokémon Go Field Research quests explained
Field research are daily missions collected one at a time by spinning a PokéStop, and will involve finding certain creatures, engaging in battles and more.
Every day PokéStops will give you a new quest, and each type of quest can have one of many different rewards, from previously Raid-exclusive consumables such as TMs and Rare Candy and common items such as Poké Balls.
Examples of quest types include:
Some of these quest rewards even give you the chance to catch a mystery Pokémon. There's nothing exclusive here, but there does include uncommon and rare Pokémon, such as Tangela and Chansey, depending on the quest in particular.
It's also worth knowing that the quests and associated rewards on offer rotate in a monthly basis. Additionally, some quests can have different rewards, so 'Make 5 Nice Throws' could offer you Balls or the chance to catch a mystery creature. So if you are after a particular Pokémon, make sure you get the variant that has the creature catch as a reward.
Finally, it's also worth knowing that if you pick up a quest, you are free to delete it and catch another by spinning another Pokéstop. You can also complete as many as you like in a day - so when you have space in your inventory, return to a PokéStop to start quest. Spin the same Pokéstop and you'll just get the same quest again though - Pokéstops give out set rewards, that are generally tailored to their location, which refresh every day at midnight. So if you want a new quest you'll need to spin another stop.
Research Breakthroughs explained
Completing one Field Research quest per day will give you a stamp. Get seven stamps - which will take seven days - completes something known as a Research Breakthrough.
These have even greater rewards - including Stardust and Mystery Items - as well as an encounter with a very rare or Legendary Pokémon.
You'll also receive plenty of other items too - including a chance at Rare Candy, Pokéballs, Berries, 2,000 Stardust, 3,000 XP, and a Sinnoh Stone.
The best news about these Research Breakthrough catches is they cannot run away - it has a flee chance of 0 per cent - so the pressure is off. However, it has the same catch rate as normal, so be prepared for it to break out of your balls.
This means you can use Pinap Berries, or even use it as a chance to rack up some of the harder throwing-based Special Research streaks, without any risk of it running away.
It also comes with strong IVs, too, as if the Pokémon was appearing in a Raid encounter or Egg. It always appears at level 15, which is the same for all mystery Pokémon caught from Field Research rewards.
If you're curious, here is all the Research Breakthrough rewards so far:
Research Breakthrough rewards in 2018:
Finally, the question is - when do the special reward Pokémon change in your Research Breakthrough progress? It's when you claim the reward for your final Field Research task.
So, you can complete the task, but just don't claim the reward for that task before 1pm PST / 9pm UK time of the first of the month, as doing so will activate the arrival of the Special Research reward at the top of the screen.
If it's before then, it'll be the reward for the month before (so in October, this was Suicune). Wait until after, it'll be the next month's (so in November, this is Shedinja).
To clarify further, this is when you complete the task, not open it. Even if you then open it after the change, it'll be the prior month's Pokémon. To be safe, wait until it's the new month if you want to get the latest creature.
What are Special Research quests?
Special Research quests, meanwhile, are story-based questlines with unique rewards. Unlike Field Research quests, these are fixed objectives that every player will face, and appear in the game infrequently.
The first available is 'A Mythical Discovery', with the arrival of the game's first Mythical creature - Mew - as the end reward.
Our A Mythical Discovery explains the eight steps required to unlock Mew, which includes finding specific Pokémon, participating in Raid and Gym battles, and reaching a certain Trainer level.
The arrival of Gen 2's Celebi suggests this is how other Mythicals - such as, we assume, Gen 3's Jirachi - will be released in the game, but as we've now seen with Spiritomb they won't always be restricted to Mythical Pokémon only.
Everything else you need to know about Research quests in Pokémon Go
Though the quest features are well explained in the game, there's some nuance that will help you get the most out of each objective you undertake.
