You will be purchasing: a PREMADE ARCEUS meant for Tera Raids in Pokémon Scarlet and Violet. (YOU PICK THE PLATE)

Summary

Arceus' ability Multitype allows it to change its type by holding elemental Plates. This allows Arceus to freely change types to counter Raid Pokemon, either offensively or defensively.

For a Specially Offensive Arceus build, Calm Mind, Judgment, Giga Drain, and Acid Spray are the main moves as a general attacker, but can be slightly modified to be more specialized in a particular type.

Best Tera Type

By default, Arceus has a Normal Tera type, but in order to maximize your damage output, match Arceus' Tera Type with its Plate type. As a Special Attacker, Modest nature would be best.

Best Tera Types: Best Pokemon to Terastallize

EV Spread Explanation

Tera Raid EV spreads should lean towards Bulky Offense. Max out your HP and Sp. Atk EVs, while adding the remaining EVs into Def. Give it an Elemental Plate to change its type accordingly.

Tera Raid Strategy

Arceus Tera Raid Turn-by-Turn Counter Strategy
Turns 1~3	Use Calm Mind to boost Arceus' Special Attack and Special Defense.
Optional	Use Giga Drain to restore at least 50% HP.
Turns 4~6	Use Judgment to deal damage and build Tera Orb charge.
Turns 7+	Terastallize and continue using Judgment.

Start Tera Raid battles by using Calm Mind at least three times to boost your Special Attack and Special Defense. Depending on the damage you sustained during your setup, you can use Giga Drain to recover lost HP, allowing you to freely attack after.

Use Judgment to deal damage while also building Tera Orb charge. Once you have enough Tera Orb charge, Terastallize and continue using Judgment to deal Tera-boosted damage.

Depending on your fourth move, you can incorporate it into your strategy as well. Weather and Terrain moves are best used before you repeatedly use Judgment, while other damage dealing moves can be instead used to build Tera Orb charge, allowing you to conserve Judgment's PP.
