Heat Resistant Plasteel Armor
Armor · ArmorBody4★Plasteel Armor, improved and highly resistant to heat.
Heat Resistant Plasteel Armor is 38th of 145 body armours by defense, at 640 against the 1,092 of Cold-Resistant Ancient Armor.
Wearing it also carries the effects Cold Resistance Lv. 1, Heat Resistance Lv. 2, Fire Damage Reduction Lv. 1, Attack Up (S) Lv. 4, which matters more than the raw numbers in the biomes that punish you for the wrong outfit.
Nothing is crafted from it — it is an end product, so anything you make is meant to be used rather than banked as a component.
Details
At 35 weight each it eats carry capacity fast, so bring a mount or park a chest nearby. At 324,720 gold it is worth real money to a merchant.

Where to Find Heat Resistant Plasteel Armor
The recipe is not on the Technology tree — it is locked behind a schematic you have to find first. The best single source is sea base enemy camp loot in the Sakurajima at 1.1% per container, and the table below lists every tier and where each one drops.
Every Tier of Heat Resistant Plasteel Armor
The same piece exists at 5 rarities, and the gap is not cosmetic: defense runs 400 to 640, a 1.6x swing. Which one you end up with is decided by the rarity of the schematic you built from, not by the recipe — so a legendary copy of this is worth more than the next item up built from a common one.
| Rarity | Item | Defense | HP | Durability |
|---|---|---|---|---|
| 0★ | Heat Resistant Plasteel Armor | 400 | 1300 | 18000 |
| 1★ | Heat Resistant Plasteel Armor | 520 | 1560 | 27000 |
| 2★ | Heat Resistant Plasteel Armor | 560 | 1690 | 36000 |
| 3★ | Heat Resistant Plasteel Armor | 600 | 1820 | 54000 |
| 4★ | Heat Resistant Plasteel Armor (this one) | 640 | 1950 | 72000 |
Schematics That Unlock Heat Resistant Plasteel Armor
The Technology tree hands you the plain Heat Resistant Plasteel Armor at level 53 for 5 Technology points, but nothing above that base version — the rarer builds are schematic-only. One schematic grants the recipe, and they are world loot — chests, boss Pals and the late-game pools — rather than anything you research. Higher-rarity copies of the same schematic raise the quality of what you end up crafting.
Fastest route. The fastest route is sea base enemy camp boss stashes in the Sakurajima, and the reason is the ladder rather than the top rung: that pool stocks every tier, so the common copies it hands you fuse upward into the one you want. Counting them, a top-tier Heat Resistant Plasteel Armor schematic works out at roughly 38 containers against the 94 the 4★ drop rate alone suggests. Spare low tiers are progress, not clutter. Schematics fuse five-to-one, so a lower tier with better odds can beat the top tier outright. Counts are containers of that source, not time.
| Schematic | Rarity | Where it comes from |
|---|---|---|
 Heat Resistant Plasteel Armor Schematic 4 | 4★ | Sakurajima sea base camp loot, Treasure map digs (tier 4), Sakurajima sea base camp stashes +6 more — best 1.1% (grade 5/6) |
Alternatives and Upgrades
Cold Resistant Plasteel Armor matches it exactly at 640 defense — those two differ in what they resist and what they weigh, not in raw defense, so picking between them is a swap rather than an upgrade. The next real step is Lightweight Hexolite Armor at 660; below it is Lightweight Plasteel Armor at 640.
