Dungeon where Deoxys is the only enemy that spawns, and you can't request a rescue if you faint.
The stairs on each floor is protected by the real Deoxys, which must be defeated before you can advance.
Enemies can catch thrown items, so bring a Pokemon with Thrown Item Boost if you plan to use projectiles.
Deoxys has Pressure as its ability and Speed form has high evasion, so bring lots of Max Ethers / Max Elixirs.
A Dark type Pokemon with Feint Attack can be quite effective, but beware of Attack form's Superpower.
※ None of the wild Deoxys can be recruited in this dungeon.

Boss Strategy

Deoxys (1279 HP) - Cosmic Power / Calm Mind / Recover / Teleport

• The real Deoxys essentially tries to stall while the group of 3 mirage Deoxys attack your team.
  • Attack form has the strongest attacks, so prioritize defeating it first.
  • Defense form can use Light Screen, so consider bringing a Ban Seed if you're using special attackers.
  • Speed form has high evasion, so use 100% accuracy attacks like Swift or Shock Wave if possible.
  • If all 3 mirage Deoxys are defeated, 3 more mirage Deoxys spawn on the next turn.
• Nullify Orb can be used to disable Pressure, making it easier to use moves like Discharge or Blizzard.
