Evolutionmon/Raids

A Raid is a special event that takes place within a Evolution Item House

Details
A Raid Battle is a cooperative gameplay experience that encourages Trainers to work with other Trainers to defeat an extremely powerful Pokémon known as the Raid Boss. Before a Raid Battle begins a large egg will appear atop the Inside The Evolution Item House. When the countdown above the egg reaches zero, the Raid Boss will be revealed.

There is also a special Raid called an EX Raid Battle which is an invitation-only Raid. A trainer will receive a notification along with with time, date and location; along with an EX Raid Pass to gain entry into the Raid.

Eggs start to appear at 5:00 AM and end at 7:45 PM local time (5:45pm for the Americas).

Raid Passes
Before a Trainer can battle the Raid Boss, they'll need a Raid Pass. Trainers can receive one free Raid Pass per day by visiting a Evolution Item House, but can only hold one at a time. A Premium Raid Pass may also be purchased from the in-game Shop.

Rewards
Completing a Raid Battle for the first time will always award 1,000 Stardust. After defeating a Raid Boss, Trainers receive a collection of rewards which depend on the tier of defeated Raid Boss.

Bonus Challenge
After successfully defeating the Raid Boss and being rewarded with Items, there are Raid Battle statistics shown to Trainer with amount of Premier Balls given to them. The player can then go to the Bonus Challenge, which is an opportunity to catch the Raid Boss as if it were a Pokémon in the wild, but with a significant difference. The player does not have their currently owned Poké Balls for use but only the Premier Balls that they have been rewarded for performance in won Raid Battle.
