The Legendary Cold-Resistant Ancient Armor is the top-tier version of Palworld’s cold-focused Ancient body armor, added in the 1.0 update. It carries the highest defense, health, and durability of the set, and it can only be crafted once you hold its Schematic 4. That schematic is a rare drop, so most players either grind a Hard Mode tower boss for it or build it up from lower-tier copies.
Quick answer: Cold-Resistant Ancient Armor Schematic 4 (Legendary) drops at roughly 5% from Marcus and Faleris on Hard Mode at the PIDF Tower. You can also craft it by combining five copies of Cold-Resistant Ancient Armor Schematic 3 at the Ancient Workbench.
Where the Legendary schematic drops
The Legendary schematic comes from Hard Mode tower boss fights, and it also has a small chance to appear in certain treasure rewards. Every source shares the same low drop rate, so expect repeated attempts rather than a single guaranteed pull.
| Source | Details |
|---|---|
| Marcus and Faleris (Hard Mode) | PIDF Tower, easternmost Desiccated Desert, ~5% chance |
| Victor and Shadowbeak (Hard Mode) | PAL Genetic Research Unit Tower, Astral Mountains |
| Treasure Box | Rare drop from certain boxes |
| Treasure Map reward | Rare drop when following a mapped location |
The same Marcus and Faleris Hard Mode run can also yield the Heat-Resistant Ancient Armor Schematic 4, so a single farming loop covers both Legendary Ancient armors.
Marcus and Faleris — PIDF Tower
This is the most reliable farm. Marcus and Faleris sit at the PIDF Tower at coordinates 556, 336, on the far eastern edge of the Desiccated Desert. On Hard Mode the boss has 526,800 HP, and the Legendary schematic rolls its ~5% chance on each clear.
Victor and Shadowbeak — PAL Genetic Research Unit Tower
Victor and Shadowbeak drop the same schematic on Hard Mode. Their tower is the PAL Genetic Research Unit Tower near the center of the Astral Mountains, at coordinates -149, 447. The drop rate here is also low, so plan on multiple clears.
Unlock and clear the Hard Mode fight
F begins the standard Join Boss Battle, while V begins Join Boss Battle (Hard). Only the Hard version can roll the Legendary schematic.Craft the schematic from lower tiers
If the drop refuses to appear, you can build the Legendary schematic instead. Cold-Resistant Ancient Armor schematics come in four tiers, and each higher tier is made from five copies of the one directly below it. Five Schematic 3 produce a single Schematic 4, which is the Legendary version.
| Schematic tier | Rarity | Made from |
|---|---|---|
| Schematic 1 | Base | Loot drops |
| Schematic 2 | — | Schematic 1 x5 |
| Schematic 3 | Epic | Schematic 2 x5 |
| Schematic 4 | Legendary | Schematic 3 x5 |
Lower-tier copies also turn up through World Tree fishing, relic recycling, and Treasure Maps, which all feed the same upgrade chain. Once you hold Schematic 4, the Ancient Workbench handles both the combining and the armor recipe.
Materials to craft the Legendary armor
With Schematic 4 in your inventory, you can craft the armor at the Ancient Workbench. The recipe leans on high-end late-game resources, so gather them before you start.
| Item | Materials |
|---|---|
 Legendary Cold-Resistant Ancient Armor | Paloxite Ingot x60 AI Core x10 Cryogenic Coolant x100 Ancient Civilization Parts x9 |
The finished armor carries Cold Resistance Lv. 3, Heat Resistance Lv. 2, Ice Damage Reduction Lv. 1, and Attack Up (S) Lv. 4. That mix makes it a full-cold-resistance set that still holds up in warmer zones and adds a small offensive boost.
Stats and rarity tiers compared
Every stat on the Legendary version beats the Common version, making it a straight upgrade. Defense climbs from 840 to 1092, health from 2400 to 3120, and durability from 25000 all the way to 100000.
| Rarity | Defense | Health | Durability |
|---|---|---|---|
| Common | 840 | 2400 | 25000 |
| Uncommon | 924 | 2640 | 37500 |
| Rare | 966 | 2760 | 50000 |
| Epic | 1008 | 2880 | 75000 |
| Legendary | 1092 | 3120 | 100000 |
The Attack Up (S) bonus also scales with rarity, rising from Lv. 1 at Uncommon to Lv. 4 at Legendary, so the top tier gives both the strongest defense and the largest attack boost.
Confirm the schematic dropped
After a Hard Mode clear, open your inventory and check the loot. A successful roll shows Cold-Resistant Ancient Armor Schematic 4 listed with Legendary rarity. If the run only gives you common rewards and no schematic, the roll failed and you need to run the fight again.
Keep the Schematic 4 in your inventory rather than in storage. The crafting recipe only appears while the schematic is carried, and with the materials on hand the Ancient Workbench will let you build the full Legendary Cold-Resistant Ancient Armor for the coldest regions of the map.
