Under Trick Room, Ariados's terrible Speed becomes its best asset — it 'outspeeds' nearly everything when turns are reversed. Only weak to Fire, Flying, Psychic, and Rock. Known as the Long Leg Pokemon. Built to hit on the physical side.

Ariados's spread isn't flashy. Attack leads, Speed trails, 1 stats clear the bar. Moderately hard to find and worth 2 Attack EVs, on a fast 800K XP curve.

Focus Sash guarantees Ariados survives one hit from full HP. That's enough to get Toxic Spikes up and fire off Sticky Web before going down. Sniper and max HP and Attack EVs maximize first-turn impact.

Ariados can't be caught in Scarlet & Violet. Transfer Spinarak from Gold, Crystal, or HeartGold and evolve through the 2-stage line to get it. The step cards below map the full chain.

How to Obtain Ariados in Scarlet & Violet

  1. Ariados
    Step 2Ariados
  • Ariados has a 400 base stat total and ranks as C-Tier — a situational pick that fills a niche. It works best as a trick room.

  • Ariados's biggest threats include Charizard (Fire), Aerodactyl (Flying), and Espeon (Psychic), all carrying super-effective STAB moves. Rock-type attackers are also a problem. At base 40 Speed, Ariados won't outrun any of these threats so switching to a resist is usually the safer play.

  • Spinarak evolves into Ariados at level 22. Ariados is the fully evolved form. It sits at 400 BST in its evolved form.

  • Swarm is the go-to ability for Ariados. It strengthens bug moves to inflict 1.5× damage at 1/3 max HP or less. Its hidden ability Sniper can work in specific setups. Insomnia is the other option — pick based on what your team needs.

  • Ariados fills the trick room role. It's leaning toward the physical side (base 90 Attack). Base 40 Speed is low. Priority moves or Trick Room are the way to go. And it's enough bulk to take a hit or two.

  • Ariados appears in 17 games, including Gold & Silver, Crystal, and Ruby & Sapphire.

Ariados first appeared in Gold & Silver and has been available in 17 games across 8 generations. Obtainable through wild encounters in most titles where it appears.
