Normal and Fighting moves don't affect Decidueye at all — that's the advantage of Grass/Ghost typing. It needs some investment to avoid getting outsped. Known as the Arrow Quill Pokemon. Flexible enough to run physical or special sets.

Attack and Sp. Atk carry most of Decidueye's stat budget. Speed's the obvious dump stat. Tough to catch and yields 3 Attack EVs. Follows a 1.06M XP medium-slow curve.

It nocks its arrow quills and shoots them at opponents. When it simply can’t afford to miss, it tugs the vine on its head to improve its focus.

Ultra Sun

Decidueye can nock and fire an arrow at an enemy in a tenth of a second, so its battles are decided in the blink of an eye.

Decidueye Weakness

Avg

Decidueye is weak to Fire, Ice, Flying, Ghost, and Dark-type moves. On the flip side, it's immune to Normal and Fighting-type moves entirely. 4 resistances help offset the weaknesses. Decidueye's special bulk (base 100 Sp.Def) helps absorb special-type weaknesses, though physical moves exploit the lower Defense.

End of the line. Decidueye caps a three-stage chain that started at Rowlet. Breeding produces the base form, and eggs are quick to hatch. Attack grew the most through evolution (+52 over Rowlet), and Decidueye peaks at 530 total stats.

For a setup attacker, Decidueye wants flexible EVs EVs and Decidiumz. The Hardy nature tilts toward balanced duty, and Overgrow contributes without taking a move slot.

Egg moves make a real difference. Decidueye gets Baton Pass and Confuse Ray exclusively through breeding, filling gaps that TMs and level-up can't touch. Coverage across 7 types rounds out the picture alongside Frenzy Plant and Leaf Storm.

You're catching Rowlet first, not Decidueye. Rowlet appears at moderate rates in the encounters below. The step cards map the full 3-stage chain with evolution methods between each stage.

    Step 3Decidueye
  • We rate Decidueye B-Tier — a solid choice for the right team. At 530 BST, it fits the attacker role. Base 107 Attack stands out.

  • Decidueye's biggest threats include Volcarona (Fire), Lapras (Ice), and Dodrio (Flying), all carrying super-effective STAB moves. Ghost and Dark-type attackers are also a problem. With 5 weakness types, most competitive teams carry at least one counter.

  • Dartrix evolves into Decidueye at level 34. Decidueye is the final evolution in a 4-stage line starting from Rowlet. At 530 BST, it's got solid stats to work with.

  • Overgrow is the go-to ability for Decidueye. It strengthens grass moves to inflict 1.5× damage at 1/3 max HP or less. Its hidden ability Long Reach can work in specific setups.

  • Base 70 Speed is workable — faster than some, slower than many. On offense, Decidueye is a mixed attacker — base 107 Attack and 100 Sp. Atk. Defensively? Enough bulk to take a hit or two. Best used as an attacker.

  • Decidueye can be found in Scarlet & Violet, Legends: Arceus, Sword & Shield, Sun & Moon, and Ultra Sun & Ultra Moon.

Since debuting in Sun & Moon, Decidueye has appeared in 5 titles over 3 generations. Along the way, it received a Hisuian form in Generation 8, keeping it relevant across different competitive metas.
