General Recommendations

• Avoid using Pokemon with a weakness to Flying, Grass, Ghost, or Fighting moves. Fainting in battle reduces the timer, and if it reaches zero before Decidueye is defeated, everyone will fail the raid battle.
• Avoid using Ice-Type Pokemon. Although Ice is strong against Grass, Decidueye has Fighting-Type moves, which are super effective against Rock-Types.
• Use Level 100 Pokemon to maximize your chance of successfully completing the raid.
• Use Vitamins to maximize your Pokemon’s key stats to increase your chance of successfully completing the Raid.
• Use Cheers when necessary
  • Go For It! ~ Boosts Attacking stats.
  • Heal Up! ~ Heals HP and cures Status conditions.
• Use moves which reduce Decidueye’s stats
  • Reduce Def or Sp.Def to take it down faster.
  • Reduce Atk to prevent it from fainting your Pokemon.
• Use Pokemon with a Fire, Flying, Bug, Poison Tera-Type to take down its Tera Shield.
