Pokemon Scarlet and Violet trainers face an exceptional challenge as Decidueye bearing the prestigious Mightiest Mark arrives in 7-star Tera Raid Battles. This formidable opponent represents the pinnacle of raid content, requiring strategic preparation and coordinated teamwork.
The Grass and Ghost dual-type archer Pokemon, evolved from Rowlet originally discovered in the Alola region, presents unique tactical considerations. Its Flying Tera type transformation during battle introduces unexpected defensive advantages that demand specialized counter strategies.
Similar to the Charizard event in December, this Decidueye carries the exclusive Mightiest Mark designation, restricting capture to a single successful attempt per player. This limitation emphasizes the importance of thorough preparation before engaging in combat.
Securing this Pokemon remains exclusively possible through Tera Raid Battle participation. Decidueye doesn’t appear in Paldea’s regional Pokedex records and cannot be encountered through standard wild Pokemon encounters.

Decidueye Tera Raid Battle dates
Trainers receive two separate weekend opportunities to challenge this elite raid battle. During these active periods, you may participate in unlimited attempts against Decidueye, though the capture opportunity remains strictly limited to one successful completion.
The initial event window commences March 17 at 00:00 UTC, continuing through March 19 until 23:59 UTC. This three-day period provides ample time for multiple practice runs and strategy refinement before your capture attempt.
A second chance arrives the following weekend beginning March 24 at midnight UTC and concluding March 26 at 23:59 UTC. This scheduling accommodates players who missed the first window or require additional preparation time.
Pro Tip: Use your first weekend attempts for team coordination testing and move learning without pressure. Save your capture for the second weekend once you’ve optimized your strategy.
Where are the Tera Raid Battles?
Throughout the Paldea region, shimmering Tera Raid crystals mark available battle locations on your map interface. These radiant formations appear in varied colors corresponding to different difficulty tiers, with black crystals specifically designating the elite 7-star challenge level.

Successfully identifying these locations requires regular map consultation as crystal respawns occur daily. Prioritize checking areas you’ve previously visited, as familiar locations often yield higher-level raid opportunities.
Location Strategy: Concentrate your search in the central and northern regions of Paldea, where 7-star raids appear more frequently. Save time by using the map’s raid filter to highlight black crystal locations instantly.
Every 7-star Tera Raid Battle mandates a full four-trainer team, eliminating solo completion possibilities. The most effective approach involves organizing pre-arranged parties where members can assign specific roles and coordinate complementary move sets.
Random matchmaking through solo queue entry pairs you with unpredictable team compositions, significantly reducing victory consistency. Coordinated teams can implement sophisticated strategies like stat manipulation, type resistance stacking, and coordinated healing rotations.
Team Composition Essentials: Include at least one Pokemon with healing capabilities, one with stat-lowering moves, and two dedicated damage dealers specializing in super-effective attacks.
Common Mistakes to Avoid: Don’t bring Pokemon weak to Flying or Ghost moves. Avoid stat-raising moves that Decidueye can clear with its ability. Never use moves that might trigger its counter-attack patterns prematurely.
Electric-type Pokemon like Miraidon or Bellibolt prove exceptionally effective, while Ice-types such as Baxcalibur and Rock-types like Garganacl offer reliable alternative counters.
Before accessing these high-level raid battles, players must complete the primary storyline content, including the final credits sequence. This achievement unlocks tier five, six, and seven raid battles across the Paldea region.
Preparation should include leveling your counter Pokemon to at least level 75, ensuring they hold appropriate held items, and verifying their move sets counter Decidueye’s dual typing effectively.
Pre-Raid Checklist: Verify your Pokemon’s levels, equip items like Shell Bell or Expert Belt, and practice timing your cheers for maximum team benefit.
