The Pokemon Go Rising Shadows event will bring the Season of Rising Heroes to a close, so here’s everything you need to know about it – including details of the new Shadow Raid Battles.

It’s been a busy three months featuring Elite Raids and loads of Special Research quests, but the Season of Heroes is almost over. Before that happens, though, there’s one final event to enjoy: Rising Shadows.

You might have already guessed from the name, but this season-ending event is all about the villainous Team Go Rocket. This time, they’ll be taking over Gyms to introduce Shadow Raid Battles to the game.

Here’s everything you need to know about the Rising Shadows event in Pokemon Go.

Shadow Raid Battles make their debut

Shadow Raid Battles will finally make their Pokemon Go debut during the Rising Shadows event, with powerful 1-Star, 3-Star, and 5-Star Shadow Pokemon appearing at select Gyms that have been taken over by Team Go Rocket.

Shadow Raid Bosses will become enraged as you battle them, leading to an increase in their attack and defense. They can be subdued with Purified Gems, a new item that can be formed with Shadow Shards dropped by Team Go Rocket members.
