Headwear

Headwear items are equipped in the "Head" slot. The player can only equip one headwear item at a time; picking up new headwear drops the player's current one.

Headwear	Effect	Notes
Miner's Cap	When the player moves, all walls adjacent to the player are automatically dug. Increases digging level by 1 to a maximum of level 3. Increases the player's light radius by 1. If no torch it equipped, it grants the light level of a Torch.	Increased digging level from Scroll of Gigantism is applied after the Miner's Cap. Likewise, autodigs aren't affected by Gigantism. Makes it impossible to perform "tactical digs". The player can still dig normally with the Pickaxe if the wall isn't destroyed first.  If used with the Blood Shovel, the player will still take damage from digging non-dirt tiles.
Monocle	Allows the player to see all items on the level, including those behind walls and in containers. Shows what item a shrine will drop if it is bombed. Reveals hidden Wraiths, Wights, Ghasts, and Ghouls.	Allows the player to determine whether or not a crate or barrel has items in it. Also shows walls that contain diamonds (or gold piles for All Zones Mode runs) or travel runes, even where the player does not have vision.
Telepathy Circlet	Allows the player to see all monsters and NPCs, even where they do not have vision. Reveals hidden Wraiths, Wights, Ghasts, and Ghouls.	Does not alert enemies of the player's presence.
Helmet	Provides 0.5 armor rating.	Stacks with other armor items.
Crown of Thorns	Heals 0.5 health for every 10 enemies killed. Deals 0.5 damage to the player upon picking up (this damage cannot be prevented).	The number of kills needed for a heal is halved when combined with a blood weapon.
Crown of Greed	Doubles all gold pick ups, but drains 1 gold per beat.	Drops from the Shopkeeper only. Will always kill the Monk upon picking up.
Crown of Teleportation	Prevents all damage from one hit, then breaks. Upon breaking, the player is teleported to the Shop. If there is no shop on the floor, the player is teleported to a random spot.	Glass items will not break when the player is hit while wearing this.
Glass Jaw	Doubles the damage dealt by the player's attack, including damage bonuses from other equipment. The player dies instantly upon taking damage. Breaks if the player takes damage.	Total attack damage can be calculated by this formula: ((weapon's base damage × weapon multiplier) + damage bonuses) × 2 = total attack damage The Glass Jaw is the only damage multiplier that includes damage bonuses from other equipment such as the Strength Charm. It also multiplies damage gained from other multipliers such as the Karate Gi. Taking damage with a Potion equipped will consume the potion and break the jaw without killing the player.
Blast Helm	Makes the player immune to the damage from explosions. Bombs the player uses instantly detonate. Gives 3 Bombs when picked up for the first time.	Being hit by any explosion (from bombs detonated by the player or otherwise) gives the player 2 frames of invincibility. Also immediately detonates bombs placed with the Bomb spell.
Sunglasses	Increases attack damage by 1, but enemies and NPCs appear as silhouettes.	The gameplay option "Always Show Enemy Hearts" does not work when the Sunglasses are equipped.
Spiked Ears	Increases attack damage by 2. The player does not trigger tempo traps and cannot be deafened. Breaks upon a missed beat.	Does not break when taking damage. Does not break when falling through trapdoors.
