Here’s the official invitation from Niantic, the developer of the phenomenal Pokemon Go as a celebration of the game’s first anniversary. It is the Pokemon Go Raid Battle feature finally lives now, horray!
The Simple Requirements:
- Have Pokemon Go installed (of course).
- Level 5 0r higher trainer.
- The countdown timer of the Egg above Gym reaches zero.
- Have the Raid Pass.
Since the release news from Niantic, trainers may see a large pink Egg above Gym, it has countdown timer with it, so you probably want to stick around at the Gym if the countdown is going to reach zero because the Raid Boss will appear. And don’t worry about the Raid Pass, you can have one freely everyday when you visit a Gym.
The system allows up to 20 trainers to work together to defeat the Raid Boss within three minutes time limit, and then, if you win you will have a chance to catch that Pokemon, in additional, you will also receive a selection of rewards, which can include Rare Candies, Golden Razz Berries, and two types of Technical Machines (Fast TMs and Charged TMs).
