How to Evolve Duosion

Duosion evolves into Reuniclus exactly at level 41. There are no trading requirements, evolutionary stones, friendship thresholds, or time-of-day restrictions involved in this process.

Since Duosion evolves from Solosis at level 32, you only need nine additional levels to reach its final stage. To speed up this process, equip Duosion with a Lucky Egg to boost experience yield by 50% during wild encounters or trainer battles.

Farming EXP Candies L and XL from 5-star and 6-star Tera Raids is the fastest leveling method in modern generations. Alternatively, battling high-yield normal-types like Chansey or Blissey in specific outbreak zones will push Duosion to level 41 in minutes.

Evolving Duosion grants you a base 125 Special Attack and base 110 HP stat monster. Reuniclus earns a solid 7.5/10 rating in competitive play, functioning primarily as a bulky Trick Room sweeper or a Calm Mind wallbreaker.

Its base 30 Speed makes it reliably outspeed almost the entire metagame while Trick Room is active. Without Trick Room, Reuniclus relies heavily on its natural bulk and the move Recover to survive hits before retaliating.

The defining reason to use Reuniclus over other Psychic-types is the ability Magic Guard. This ability prevents all indirect damage. Reuniclus takes zero damage from Stealth Rock, Spikes, Toxic, Leech Seed, Sandstorm, or Hail.

Reuniclus is a highly specialized Pokémon. It fits perfectly on dedicated Trick Room teams or bulky offense builds needing a reliable win condition against defensive stall teams.

• Pros: Magic Guard allows free use of a Life Orb, boosting damage by 30% without suffering the standard 10% HP recoil per attack. High natural physical bulk when invested allows it to set up Calm Mind safely against passive opponents.
• Cons: Base 30 Speed is dead weight against fast hyper-offense teams if Trick Room is not active. It is highly vulnerable to common Dark-type attacks like Knock Off and Ghost-type moves like Shadow Ball.

If you prefer fast sweepers like Dragapult or Cinderace, Reuniclus will disrupt your team's momentum. If you play methodical, bulky offense, Reuniclus acts as a premier stall-breaker.

Once Duosion hits level 41, Reuniclus needs a specific moveset to maximize its potential. The Calm Mind setup variant is the most consistent across standard singles formats.

Run Psyshock over Psychic to hit special walls like Blissey on their weaker Defense stat. Focus Blast provides essential coverage against Dark and Steel-types that resist or are immune to Psychic attacks.

Recover is mandatory to keep Reuniclus healthy throughout a match, allowing it to shrug off direct attacks. The final slot belongs to Calm Mind to boost Special Attack and Special Defense simultaneously, turning it into an unbreakable wall against special attackers.

To maximize Reuniclus's base 110 HP, competitive builds require a 252 HP EV investment. The remaining EVs depend entirely on your chosen role.

For a Calm Mind wallbreaker, invest 252 EVs into Defense with a Bold nature. This physical bulk allows Reuniclus to survive physical hits like Earthquake or Close Combat while Calm Mind boosts its Special Defense.

For a dedicated Trick Room sweeper, shift the 252 EVs into Special Attack with a Quiet nature. A Quiet nature increases Special Attack while lowering Speed, ensuring Reuniclus moves first under Trick Room conditions. Ensure its Speed IV is set to 0 for maximum Trick Room efficiency.
