The Exact Evolution Trigger: Peat Block and Lunar Cycles
Ursaring evolves into
Ursaluna exclusively when exposed to a Peat Block while an in-game full moon is active. This mechanic bypasses level requirements entirely. The Peat Block functions as a consumable item, identical in application to an Evolution Stone. Once applied from the player's bag, the item is destroyed, and the evolution sequence begins.
The environmental condition of the full moon operates differently depending on the game engine. In Pokémon Legends:
Arceus, the lunar cycle is tied to the game's resting mechanic. Players can force cycle the moon phases by repeatedly resting at a base camp until nightfall. Checking the sky or verifying if the Peat Block reads as 'compatible' in the inventory confirms the correct phase.
In Pokémon Scarlet & Violet, the day and night cycle runs on a strict 72-minute real-world timer. Nighttime occupies approximately 34 minutes of this cycle. The moon phase advances by one stage every in-game night. Players cannot simply rest in a bed to skip to the next night; they must either wait in real-time or manipulate the Nintendo Switch system clock to bypass the 72-minute intervals until a full moon appears.
Procuring the Peat Block in Scarlet & Violet
Finding a Peat Block in Generation 9 requires accessing specific DLC areas or utilizing the auction system. A guaranteed static Peat Block spawns in the Timeless Woods, located in the Kitakami region introduced in The Teal Mask DLC. Players will find it as a sparkling overworld item near the center of the woods.
Players without the DLC must rely on the Porto Marinada auctions in the Paldea region. The auction inventory resets every in-game day (every 72 minutes) or when the player restarts the game after changing the system clock. To farm the item efficiently, save the game in front of the auctioneers, close the software, advance the Switch clock by two hours, and reload. Repeat this process until a vendor offers the Peat Block.
Auction prices fluctuate based on NPC bidding behavior. Players should bring at least 10,000 Pokédollars to secure the Peat Block, though aggressive NPC bidding can push the final price higher. Using the save-reset method ensures you do not overspend on a single evolution item.
Procuring the Peat Block in Legends: Arceus
In the Hisui region, Peat Blocks are hidden beneath the earth and require the
Ursaluna ride Pokémon to unearth them. The item drop rates are heavily weighted toward the Crimson Mirelands map. Players must mount
Ursaluna and follow the colored radar signals projecting from its head.
A yellow radar indicates a hidden item is nearby, while a red, flashing radar signifies the player is directly on top of the dig spot. Peat Blocks share a loot pool with Black Augurites, Evolution Stones, and various crafting materials. The drop rate for a Peat Block is approximately 5 to 10 percent per successful dig in the Crimson Mirelands.
To optimize farming, players should run a specific route through the Sludge Mound and Scarlet Bog areas, digging up every item node. Once all nodes are exhausted, return to Jubilife Village to reset the map spawns, then re-enter the Crimson Mirelands to repeat the loop.
Competitive Verdict: Is Ursaluna Worth It?
Verdict: 9.5/10.
Ursaluna operates as a tier-defining physical wallbreaker and Trick Room sweeper in both Singles (OU) and VGC formats. Its base 140 Attack stat, combined with the Guts ability, generates physical damage output that breaks through dedicated physical walls. The standard competitive set requires
Ursaluna to hold a Flame Orb, which inflicts a burn at the end of the first turn. This burn activates Guts, granting a 1.5x multiplier to its Attack stat while ignoring the standard damage penalty associated with the burn status.
The primary offensive tool is Facade. When a Pokémon is burned, Facade's base power doubles from 70 to 140. When combined with the Same Type Attack Bonus (STAB) and the Guts multiplier, a neutral Facade from
Ursaluna will 2HKO physically defensive staples like
Corviknight and
Dondozo. Headlong Rush provides a 120-base power Ground-type STAB option that eliminates Rock and Steel types attempting to resist Facade.
Ursaluna boasts excellent natural bulk with 130 base HP and 105 base Defense, allowing it to survive neutral hits comfortably. Its Normal/Ground typing grants critical immunities to Ghost and Electric-type attacks, providing safe switch-in opportunities against Pokémon like
Gholdengo or
Regieleki.
Weaknesses and Meta Counters
Despite its overwhelming power,
Ursaluna suffers from a base 50 Speed stat. It relies entirely on Trick Room support to move first. Without Trick Room active,
Ursaluna will take significant damage before it can execute an attack. Furthermore, the Flame Orb puts
Ursaluna on a strict timer. The chip damage from the burn, combined with entry hazards like Spikes or Stealth Rock, rapidly depletes its health pool.
Priority moves are
Ursaluna's greatest threat. Because Trick Room does not alter priority brackets, moves like
Rillaboom's Grassy Glide,
Urshifu's Aqua Jet, or
Dragonite's Extreme Speed will strike
Ursaluna before it can act. Players must pair
Ursaluna with support Pokémon like
Farigiraf or Indeedee-F, whose abilities (Armor Tail and Psychic Surge, respectively) block incoming priority attacks.
Ghost-type Pokémon with the Levitate ability or an Air Balloon completely wall
Ursaluna's dual STAB combination. Defensive Rotom-Wash and
Orthworm (with Earth Eater) can pivot into
Ursaluna safely and stall out its Trick Room turns while the burn damage accumulates.
Optimal EV Spreads and Movesets
A competitive Trick Room
Ursaluna requires a Brave nature to maximize Attack while lowering Speed. The ideal IV spread includes 0 Speed IVs to guarantee it is as slow as possible, ensuring it moves first under Trick Room conditions. The EV allocation is straightforward: 252 HP / 252 Attack / 4 Special Defense.
The standard moveset consists of Facade, Headlong Rush, Earthquake, and Protect. Protect is mandatory in VGC formats to stall out the first turn safely, guaranteeing the Flame Orb activates without taking unnecessary damage. In Singles formats, Swords Dance replaces Protect to punish passive defensive switches, pushing
Ursaluna's Attack to mathematically unwallable levels.
Alternative coverage options include Ice Punch or Fire Punch to hit specific threats like
Corviknight or defensive Landorus-Therian on the switch, though the raw damage of a Guts-boosted Facade often out-damages super-effective elemental punches.
Eviolite Ursaring vs. Ursaluna
Some players consider keeping
Ursaring unevolved to utilize the Eviolite item, which boosts its base 75 Defense and 75 Special Defense by 1.5x. While this provides
Ursaring with respectable mixed bulk, it fundamentally fails as a competitive strategy. Verdict for Eviolite
Ursaring: 3/10.
Ursaring lacks the secondary Ground typing that gives
Ursaluna its Electric immunity and high-base-power STAB options. More importantly, running Eviolite means
Ursaring cannot hold a Flame Orb or Toxic Orb. This forces players to rely on the opponent to inflict a status condition to activate Guts or Quick Feet, which is highly inconsistent.
Without the status orb,
Ursaring's damage output is mediocre by modern competitive standards. The sheer offensive pressure and superior physical bulk of
Ursaluna make evolving the strictly optimal choice for any competitive team.
The Bloodmoon Ursaluna Exception
It is mechanically impossible to evolve an
Ursaring into Bloodmoon
Ursaluna. Bloodmoon
Ursaluna is an entirely separate form with a different stat distribution, ability, and movepool. It functions as a Special Attacker rather than a Physical Attacker.
This specific Pokémon is locked behind a static encounter in The Teal Mask DLC. Players must complete Perrin's photography questline in the Timeless Woods to battle and catch it. Applying a Peat Block to an
Ursaring during a full moon will always yield the standard Ground/Normal physical
Ursaluna, regardless of whether the evolution occurs in the Timeless Woods or any other location.

Frequently Asked Questions About Evolving Ursaring
Does Ursaring need to hold the Peat Block to evolve?
No. The Peat Block is a consumable evolution item, not a held item. You select it directly from your inventory and apply it to Ursaring during a full moon to trigger the evolution sequence.
Can I evolve Ursaring into Bloodmoon Ursaluna?
No. Bloodmoon Ursaluna is a unique, static encounter tied to a specific questline in The Teal Mask DLC. Standard Ursaring will only ever evolve into the regular physical-attacking Ursaluna.
How long does a full moon last in Scarlet and Violet?
The game utilizes a 72-minute real-world day and night cycle. Nighttime lasts for roughly 34 minutes. The full moon phase persists for the entirety of that specific 34-minute night window.
Does Ursaring evolve by leveling up?
Ursaring does not evolve through experience points or leveling. While Teddiursa evolves into Ursaring at level 30, reaching the final stage strictly requires the Peat Block and the full moon environmental trigger.
