Rowlet, Dartrix, and Decidueye look like one evolution line with one type chart. They aren’t. Swap the region from Alola to Hisui and the final stage keeps the name, the silhouette, and the archer gimmick — but not the typing, not the signature move, and not the single defensive trait that made the original worth building around. Standard Decidueye is immune to two entire attacking types. Hisuian Decidueye is immune to none of them, and picks up a 4x weakness in exchange.
This is what actually changes between the two forms, verified against each form’s own single-type defensive chart rather than a pre-merged summary — dual-type charts are one of the easiest facts to get wrong in a Pokemon comparison, because merging two type charts by hand produces different results than skimming a page that already tried to merge them.
The Answer at a Glance
| Form | Typing | Signature Move | What It Loses | What It Gains |
|---|---|---|---|---|
| Standard Decidueye | Grass/Ghost | Spirit Shackle (Ghost) | — | Immune to Normal + Fighting |
| Hisuian Decidueye | Grass/Fighting | Triple Arrows (Fighting) | Both immunities, gains a 4x Flying weakness | Wider resist list (6 types vs. 4), higher Attack/bulk |
Same Line, Two Different Evolution Endpoints
Rowlet evolves into Dartrix at level 17 in every game it appears in — that part never changes.[1] What changes is the second jump. In Sun/Moon, Sword/Shield, and Scarlet/Violet, Dartrix evolves into standard Decidueye at level 34.[1] In Pokemon Legends: Arceus, the regional Hisuian Dartrix evolves into Hisuian Decidueye two levels later, at level 36[2][3] — a small gap, but it’s one of several small evolution-level shifts Legends: Arceus made across its Hisuian forms, similar to how other Pokemon in that era picked up entirely new evolution conditions tied to specific locations or methods (Crabrawler, for example, only evolves at Mount Lanakila in Sun and Moon and needs an Ice Stone everywhere else, while Charjabug has four separate ways to become Vikavolt depending on the game).
You don’t get to pick which endpoint you land on by choice of level-up alone — the game version decides it. Play Legends: Arceus and Hisuian Decidueye is the only Decidueye you can raise. Play any other mainline game and you get the standard Grass/Ghost form, full stop, unless you transfer a Hisuian one in through Pokemon Home.
If you’re playing Legends: Arceus and want Hisuian Decidueye on your team as fast as possible, the fastest-safe path is simply keeping your starter Rowlet in your active party and letting normal story-mission experience carry it past both thresholds. There’s no battle facility, evolution stone, or side quest gatekeeping either jump in that game, unlike several other Hisuian lines that do require a specific method or location.
The Full Type Chart, Recomputed From Scratch
Grass alone is weak to Fire, Ice, Poison, Flying, and Bug, and resists Water, Electric, Grass, and Ground.[6] Layer Ghost on top and the picture changes completely: Ghost is weak to Ghost and Dark, resists Poison and Bug, and is flatly immune to Normal and Fighting.[4] Multiply the two charts together — not read them side by side, actually multiply — and Poison and Bug both cancel out to neutral (Grass’s 2x weakness times Ghost’s 0.5x resistance equals a flat 1x), while the Normal and Fighting immunities pass straight through untouched.
| Standard Decidueye (Grass/Ghost) | Hisuian Decidueye (Grass/Fighting) | |
|---|---|---|
| Immune (0x) | Normal, Fighting | None |
| 4x Weak | None | Flying |
| 2x Weak | Fire, Ice, Flying, Ghost, Dark | Fire, Ice, Poison, Psychic, Fairy |
| 0.5x Resist | Water, Electric, Grass, Ground | Water, Electric, Grass, Ground, Rock, Dark |
Swap Ghost for Fighting and the immunities disappear entirely.[5] Fighting has no immunities of its own to contribute, so the merged chart falls back to whatever Grass alone provides — which is nothing but weaknesses and resistances, no free passes. Worse, Grass’s existing 2x Flying weakness stacks with Fighting’s own 2x Flying weakness, producing a 4x weak spot that standard Decidueye never has to think about.[5][6] The trade isn’t neutral: Hisuian Decidueye picks up two extra resistances (Rock and Dark, both from the Fighting half) to partly compensate, but a 4x weakness to a common attacking type is a real cost, not a wash.
The Poison case is worth walking through once, since it’s the one most summaries get backwards. Grass takes double damage from Poison on its own, a 2x multiplier. Ghost resists Poison at 0.5x. Multiply the two together (2 x 0.5) and the result is exactly 1, a flat neutral hit, not a weakness and not a resistance. Standard Decidueye’s Ghost half is quietly canceling out a weakness its Grass half would otherwise have on its own. Hisuian Decidueye doesn’t get that same cancellation, since Fighting is neutral to Poison, so the Grass half’s 2x weakness passes straight through untouched. That’s why Poison shows up as a genuine 2x weakness on the Hisuian side of the table above but not the standard side.
What Losing the Ghost Immunity Actually Costs You
The Normal immunity rarely matters — most Normal-type attackers aren’t threatening enough that dodging their neutral hits changes a game plan. The Fighting immunity is the one that bites. Fighting is one of the most common attacking types in both the wild and competitive play, and standard Decidueye simply doesn’t care: a Close Combat or a Focus Blast aimed at it does zero damage, full stop. Hisuian Decidueye takes that hit at a neutral 1x, because Fighting-type Pokemon are neutral to their own type.
There’s a second, sneakier cost. Ghost-type Pokemon can’t be trapped by moves and abilities that normally prevent switching — things like Mean Look or Shadow Tag simply don’t work on them, and they can always flee a losing matchup.[4] Standard Decidueye keeps that escape valve for free. Hisuian Decidueye doesn’t; as a Grass/Fighting type, it can be shut in by exactly the trapping tools its predecessor laughed off.
Spirit Shackle vs. Triple Arrows: Different Jobs, Not Just Different Types
The signature moves aren’t reskins of each other — they’re built for opposite roles. Spirit Shackle is an 80-power Ghost-type physical hit that pins the target in place, preventing it from switching out for the rest of the fight.[1][9] It’s a lock-in tool: use it to guarantee a follow-up hit lands on the same Pokemon, or to stop an opponent from pivoting away from a bad matchup.
Triple Arrows is a 90-power Fighting-type physical hit with a 50% chance to drop the target’s Defense by one stage, a 30% chance to flinch it, and a boosted critical-hit ratio on top.[7][8] It’s a breaker, not a trap — the Defense drop softens up bulky targets for a follow-up, and the flinch chance can steal a turn outright against anything slower. Neither move transfers between forms; standard Decidueye can’t learn Triple Arrows and Hisuian Decidueye can’t learn Spirit Shackle, by design.
The Ability Change That Nobody Connects to the Type Swap
Here’s the detail most comparisons miss entirely. When Hisuian Decidueye first appeared in Legends: Arceus, its hidden ability was Long Reach — the same hidden ability standard Decidueye has always had.[3] By the time it showed up again in Scarlet and Violet’s raid content, that hidden ability had been swapped out for something new: Scrappy, which lets Normal- and Fighting-type moves hit Ghost-type Pokemon that would otherwise resist or block them entirely.[3][10]
That’s not a random tweak. It’s a direct patch for the exact immunity Hisuian Decidueye lost. A Grass/Fighting Pokemon using a Fighting-type signature move should, in theory, be walled cold by any Ghost-type opponent — Fighting doesn’t touch Ghost at all under normal rules.[4] Scrappy erases that wall specifically for this Pokemon, turning what looks like a typing downgrade into a way to threaten Ghost-type tanks like Gholdengo or Dragapult that standard Decidueye’s own Fighting immunity would never have let it approach.[10] The type chart took something away; the ability change gave back a narrow, specific answer to the same problem.
Which One Actually Wins a Fight?
Community competitive analysis on Smogon’s forums is blunt about it: Hisuian Decidueye isn’t OU-caliber, and the expectation is it settles into UU or RU as a specialized tool rather than a top-tier pick.[10] The core issue is Breloom — same Grass/Fighting typing, 130 base Attack against Hisuian Decidueye’s 112, better Speed, and access to priority Mach Punch that Decidueye simply doesn’t have.[10] On raw stats, Breloom wins the matchup almost every time.
What keeps Hisuian Decidueye relevant at all is the Scrappy-into-Triple-Arrows combination described above — a specific answer to Ghost-type walls that Breloom, without that same interaction, doesn’t replicate as cleanly.[10][11] A common competitive build runs Swords Dance, Triple Arrows, Leaf Blade, and Knock Off with a Jolly nature, Scrappy, a Lum Berry, and a Fighting Tera Type to round out its coverage.[11]
| If you are… | Prioritize this |
|---|---|
| New to the series, just playing story mode | Whichever form your game gives you — there’s no choice to make, so focus on hitting the level-17/34 or level-36 evolution windows on schedule |
| A completionist chasing a full living Pokedex | You need both — raise standard Decidueye in a mainline game and transfer a Legends: Arceus-caught Hisuian line through Pokemon Home |
| A casual competitive player | Hisuian Decidueye with Scrappy, specifically as a Ghost-type answer — don’t expect it to be your best all-around pick |
| A hardcore optimizer building a serious team | Default to Breloom for the same typing at a higher power ceiling; only run Hisuian Decidueye if you specifically need the Scrappy/Triple Arrows tech against a Ghost-heavy metagame |

Frequently Asked Questions
Is Hisuian Decidueye strictly worse than standard Decidueye?
Not strictly — it’s differently specialized. Standard Decidueye’s two free immunities make it a safer defensive pivot, especially against Fighting-heavy teams. Hisuian Decidueye trades that safety for a narrow offensive answer to Ghost-type walls that standard Decidueye’s own Ghost typing would never let it threaten in the first place. Judge it by role, not by a single stat line.
Why does a Hisuian regional form change type instead of just changing color?
Hisuian forms across Legends: Arceus consistently reflect a rawer, more instinct-driven version of their species — Decidueye’s own in-game flavor text describes the Hisuian form as fighting at close range rather than sniping from a distance, which lines up with a melee-coded Fighting typing far more than the original’s stealth-archer Ghost typing does. The type change isn’t cosmetic; it’s the mechanical expression of a different combat identity.
Can I put Spirit Shackle on my Hisuian Decidueye or Triple Arrows on my standard one?
No. Both moves are locked to their respective form and can’t be taught across the split, by breeding, TM, or any other method currently available. That’s a deliberate design choice — letting either form learn both signature moves would erase the reason to choose one over the other.
Which form should I actually raise if I only want to build one?
If you’re not deep into competitive team-building, raise whichever one your game gives you and don’t worry about it further — both are perfectly serviceable outside of high-level play. If you are optimizing for competitive Fighting-type coverage specifically, Hisuian Decidueye’s Scrappy interaction with Ghost-types is the more useful pick despite Breloom’s higher raw stats, because it solves a matchup problem Breloom can’t.
