Plasteel Helmet
Armor · ArmorHead2★A Plasteel headpiece that raises defense while cutting weight, sitting at the edge of what the technology can do.
Plasteel Helmet is 15th of 202 head pieces by defense, at 338 against the 650 of Ancient Helm.
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 12 weight each it eats carry capacity fast, so bring a mount or park a chest nearby. At 151,020 gold it is worth real money to a merchant.
Plasteel Helmet Crafting Recipe
Crafting it takes 71 materials across 3 types.
Where to Find Plasteel Helmet
The recipe is not on the Technology tree — it is locked behind a schematic you have to find first. The best single source is treasure map digs (tier 4) at 6.4% per container, and the table below lists every tier and where each one drops.
Every Tier of Plasteel Helmet
The same piece exists at 5 rarities, and the gap is not cosmetic: defense runs 260 to 390, a 1.5x 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★ | Plasteel Helmet | 260 | 600 | 18000 |
| 1★ | Plasteel Helmet | 312 | 720 | 27000 |
| 2★ | Plasteel Helmet (this one) | 338 | 780 | 36000 |
| 3★ | Plasteel Helmet | 364 | 840 | 54000 |
| 4★ | Plasteel Helmet | 390 | 900 | 72000 |
Schematics That Unlock Plasteel Helmet
The Technology tree hands you the plain Plasteel Helmet at level 51 for 4 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 Plasteel Helmet schematic works out at roughly 30 containers against the 71 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 |
|---|---|---|
| 2★ | Treasure map digs (tier 4), Sakurajima chests, fishing in Sakurajima +4 more — best 6.4% (grade 5/6) |
Alternatives and Upgrades
Step up from here and you get Hexolite Helmet at 350 defense; step down and it is Plasteel Helmet at 312. That gap is the honest measure of whether an upgrade is worth the materials right now.
