Doloc Town Hats: All 20 Hats, Their Effects and Where to Get Them

Hats are not armour, with three exceptions

Hats occupy the head slot and most of them have a defense value of 0. Only three raise it: Cotton Winter Hat gives 3, Felt Mushroom Hat gives 2 and Mushroom Cap gives 1. If you are dying in the Old City Ruins, no hat in the game is going to fix that; the faction badge accessories and your drone loadout matter far more.

What hats actually do is change one system each. That is why the useful list is short and worth memorising, and why swapping hats before a specific activity is the normal way to play rather than finding one best hat and never changing it.

The six hats that change a mechanic

• Welder's Mask — immunity to acid rain damage. You are wearing it from the start of the game, which is why acid rain feels harmless early and then suddenly is not once you switch hats.
• Miner Hat — the Chinese wiki measures it as 10 extra gathering damage on every hit from a pickaxe-class tool, and notes the same bonus also fires for the Mechanical Greatsword, the Harvest Assistant and the Mining Rifle. The English wiki only says it increases mining efficiency with a pickaxe.
• Skull Hat — significantly increases critical hit rate. This is the only combat-stat hat in the game.
• Steel Helmet — the Chinese wiki gives the number the English wiki omits: canned food restores 50% more.
• Witch Hat — summons lightning that strikes nearby enemies at intervals. It is a passive damage source, not a triggered ability.
• Mask 66 — makes one machine series stop attacking you on sight. The Chinese wiki adds the catch: the effect breaks the moment you attack first.

Which hats are actually hard to get

Four hats are low-probability drops rather than purchases. Mask 66 comes from killing the machine it mimics and Chameleon Bug Hat comes from killing Chameleon Bugs or Acid Chameleon Bugs; both are documented on the Chinese wiki with a 200-kill pity counter, so they are a grind with a hard ceiling rather than a lottery. Skull Hat drops from gathering rock piles and large rock piles, and Chomper Hat drops from killing Chompers — neither has a documented pity threshold, which is the more annoying category.

Two hats sit behind exploration rather than combat. The Straw Hat is in a hidden chest out on the outskirts to the left of the farm, by the west cliff. The Miner Hat is in a hidden chest in the Rivervalley mining ruins, and that area only opens after you finish the Geological Scanner terraform, so it is gated by progression rather than by luck.

Three hats are festival-limited. Fried Egg Hat costs 7 Small Coppers from Kuma during the Long Night Festival. Year Beast Hat needs you to kill the Experimental Firework Machine (NY.II) in the Eastern Outskirts during the same festival, which then opens the exchange at Orlando's treasure shop. Felt Mushroom Hat costs 8 Boletus at the Mushroom Festival stall. If a festival is not running, these are simply unavailable.

The Red Pom-Pom Hat is the odd one out: it was added on Christmas Day 2025 and you get it by dialling 35123 at any phone booth in town, after which it arrives in your mailbox with the delivery letter.

Where the two wikis disagree

Two disagreements are worth recording rather than resolving. First, the English wiki's Mask 66 page says the mask makes the Type-33 series cease active attacks, while its own item description calls the mask a mimicry mask modeled after Drone 66, and the Chinese page says the effect applies to the Type-66. Three different machine designations for one item across two sources is not something we can settle from documentation alone.

Second, the Chinese wiki's hat category contains 19 pages and has no entry at all for the Little Bird Hat, which the English wiki documents with a full infobox and description. The hat is listed below on the English wiki's authority alone, with no independent confirmation and no source for how to obtain it.

All 20 hats

Effects and defense values come from the English wiki's infoboxes. Acquisition routes and the measured numbers come from the Chinese wiki, which is the only source that documents where most of these hats come from.
