How to Join the Tandemaus Raid Event

How to Join the Tandemaus Raid Event
Connect to the Internet Check the Map for Sparkling Tera Raid Crystals Join or Host an Event Tera Raid

Connect to the Internet

To encounter the Tandemaus of this event and spawn these special Tera Raid Crystals, you needed to connect your game to the Internet to update the game data. Once done, event Tera Raid crystals would appear on your map!

To connect to the Internet, simply press the X button to open the menu and press the L button to connect to the Internet.

Check the Map for Sparkling Tera Raid Crystals

After connecting to the Internet, unique Tera Raid Crystals will start appearing in the overworld. These are distinct enough from regular Tera Raid Crystals and will sparkle, as seen in the overworld, so you can determine which ones contain an Eevee!

Look for Sparkling Tera Raid Icons

Icon	Explanation
	Event Tera Raid icons will sparkle compared to regular Tera Raids.

Event Tera Raids will also appear differently on the map, as their icons will sparkle!

Join an Event Tera Raid

After connecting to the Internet and having your game data updated, you can immediately group up with other players and join Tera Raids through the Tera Raid Battle menu in the Poke Portal screen, which can be accessed from the main menu by pressing the X button.

Event Tera Raids will have a Tandemaus icon displayed in a yellow box, and the Tera Type will be shown on the upper right.

Hosting Event Tera Raids

Alternatively, you can also host Tera Raids once you find a sparkling Tera Raid Crystal in the overworld.

You can either challenge Tera Raids as a group with other players, or you can face them solo.

Event Tera Raids in Yellow Cards

An important note to keep in mind is that event Tera Raids will have yellow event cards, which can be observed from the Tera Raid preparation screen or the Tera Raid Battle Search menu in Poke Portal.

This is useful so you can determine if the Tera Raid you found or will join is an event raid, and not just a regular one!

Nintendo Switch Online Subscription Required for Online Play

Note that you need a Nintendo Switch Online subscription to host or join online Tera Raids with other players across the Internet!

Multiplayer Guide

Can Hidden Ability and Shiny Tandemaus Appear?

Tandemaus with Hidden Ability Available in 3★ Raids Up

Tandemaus with the Hidden Ability, Own Tempo, had a chance to appear in 3★ raids and up.

If you had planned on stocking up on Tandemaus with a Hidden Ability, this event was your opportunity to do so as all sparkling Tera Raid Crystals were guaranteed to have Tandemaus; you just need to check if they are 3★ or higher.

List of Hidden Abilities

Low Possibility for Shiny Tandemaus Raid

Shiny Pokemon can appear in Tera Raid Battles, but since there was no announcement that there are increased chances of Shiny Tandemaus appearing, the chances of shiny Tandemaus raids appearing may be similar to regular raids, which is low.

Best Tera Types

Normal: Same Type for Extra Damage Output

If you match Tandemaus' Normal typing with its Tera Type, you will be able to increase its offensive potential as it will now hit harder when when using a move that matches its type while it is Terastallized.
What is STAB? How to Use STAB Effectively

Ghost: Become Immune to Fighting

By Terastallizing Tandemaus to Ghost, you remove its only weakness, Fighting, and replace it with an immunity instead! Ghost will also allow Tandemaus to hit Ghost Types for STAB super-effective damage, which otherwise are immune to its STAB Normal moves.

Fighting: Hit Types that Resist Normal for STAB Super Effective Damage

By Terastallizing Tandemaus to Fighting, it is able to hit Rock and Steel Types that normally resist its Normal Type STAB moves with STAB super effective Fighting Type moves.
