Palworld Multiclimate Undershirt and Bellanoir Raid Boss offer unmatched survival and end-game rewards for daring explorers in hostile biomes.
In the vast and treacherous islands of Palworld, survival hinges on more than just a strong team of Pals. The environment itself can be a relentless foe. By 2026, players have charted the game's most hostile biomes, from the scorching sands of the Dessicated Desert to the frozen peaks of the Astral Mountains. Navigating these extremes requires specialized gear, and one accessory stands above the rest for its unparalleled utility: the Multiclimate Undershirt. This unique item offers a singular solution to the dual threats of extreme heat and bitter cold, making it an indispensable tool for any serious explorer or end-game strategist.
Unlike most protective gear in the game, the Multiclimate Undershirt cannot be found in chests or crafted at a workbench. Its acquisition is a true test of a player's progression and combat prowess. The only source for this coveted accessory is a specific, high-stakes encounter. It is a potential drop from the formidable Raid Boss, Bellanoir, or its even more challenging variant, Bellanoir Libero. This places the undershirt firmly in the category of late-game rewards, reserved for those willing to undertake a significant quest chain.
The journey to face Bellanoir begins with reaching player level 33 and constructing a Summoning Altar at a base. This structure requires 100 Stone and 20 Paldium Fragments. Once the altar is built, the real hunt begins. Players must venture into specific dungeons scattered across the Palpagos Islands to collect Bellanoir's Slab Fragments. These fragments are not guaranteed drops from every dungeon, requiring targeted exploration.
Here is a breakdown of the known dungeon sources for these fragments:
| Dungeon Name | Recommended Level | Rewards |
|---|---|---|
| Ravine Grotto | 19 | 1 Bellanoir Slab Fragment |
| Mountain Stream Grotto | 29 | 2 Bellanoir Slab Fragments |
| Cavern of Dunes | 35 | 2 Bellanoir Slab Fragments |
| Volcanic Cavern | 40 | 1 Bellanoir Slab Fragment |
| Volcanic Cavern | 40 | 1 Bellanoir Libero's Slab Fragment |
| Sacred Mountain Cavern | 45 | 2 Bellanoir Libero's Slab Fragments |
After gathering four fragments of the same type, players combine them at a crafting table to create either Bellanoir's Slab or Bellanoir Libero's Slab. This slab is the key to summoning the boss at the altar. Preparation for the ensuing battle is critical. Bellanoir is a Dark-type Pal, making it highly vulnerable to Dragon-type attacks. Players are advised to:
-
Equip the strongest available armor and weapons.
-
Assemble a team of high-level Dragon-type Pals.
-
Maximize the level of their battle base and station up to 15 powerful, preferably Dragon-type, Pals there for support.
Victory in this intense raid is not guaranteed, but the spoils are worthy of the struggle. Among the rewards, the Multiclimate Undershirt may appear, granting its wearer a significant and permanent advantage.
The ability of the undershirt is beautifully simple yet profoundly impactful. When equipped in an accessory slot, it provides complete immunity to environmental damage from both extreme heat and extreme cold. This single item nullifies the need for situational gear swaps when traversing the world's most dangerous regions. Players can freely explore Mount Obsidian's lava flows or the Astral Mountains' blizzards without a second thought.
This freedom unlocks critical late-game content. Harsh climates often guard valuable resources essential for progression, such as Coal and Sulfur deposits. Furthermore, several powerful Pals unique to these zones become accessible. Notably, three of the formidable Pal Tamer tower bosses have made their strongholds in these inhospitable areas, making the undershirt practically mandatory for those seeking to challenge them.
The true value of the Multiclimate Undershirt becomes clear when compared to alternatives. Players can obtain separate Heat Resistant Undershirts and Thermal Undershirts, but equipping both consumes two precious accessory slots. The Multiclimate version consolidates this protection into one slot, a massive efficiency gain. Beyond undershirts, the game's tech tree offers a wide array of armor with varying levels of climate resistance, from early-game Cloth Outfits to end-game Pal Metal Armor. However, these are primary armor pieces and do not offer the slot-efficient, universal protection of the unique Multiclimate Undershirt accessory.
In summary, the Multiclimate Undershirt is more than just a piece of gear; it is a milestone. Its acquisition signifies a player's readiness to conquer Palworld's final environmental challenges and claim the rewards they protect. By consolidating vital survival functions into a single inventory slot, it represents the pinnacle of exploration utility, freeing adventurers to focus on combat, Pal collection, and base building without the constant threat of the elements. For any player aiming to experience everything Palworld has to offer by 2026, securing this undershirt is a non-negotiable objective on the path to mastery.
