"Mining damage needed" is damage reduction + 1 (below that you deal no damage). "Pickaxe that can mine it" is the lowest-level pickaxe whose base mining damage alone exceeds the damage reduction. Your actual mining damage also adds the mining skill (+100 at Lv.100), gear, food and upgrades, so an earlier pickaxe may already work. Blocks with high reduction, such as Fossil Block, need more mining damage from upgrades or skills first.

Craftable walls and their health (10)

Blocks made at a crafting station that can only be placed as walls (they have no ground form). Most are decorative, and many have the same health and damage reduction as the block they are made from.

Explosive walls (4)

Walls that explode when hit. Their damage reduction is 0, so any pickaxe can hit them. Break them from a distance so you aren't caught in the blast.

Doors, fences and other wall-like placeables

Placeables that can block a path or build an enclosure instead of walls. Health values are taken from the game data; how many hits they take to break is not confirmed (according to the game's patch notes, doors regain health over time like other placed objects).

• Doors: placed between walls on both sides, they turn horizontal or vertical to match. If you break a supporting wall, the door breaks too. You can walk through an open door. Doors take no damage from ranged attacks.
• Fences: connect to nearby fences and fence gates of the same type. You can't walk through them, but projectiles can be shot over them. Fencing in a farm stops wandering cattle from eating your crops (use a fence gate of the same type as the entrance).
• Fence gates: open and close by interacting, just like doors.

How wall health and damage reduction work

• Health: the total damage needed to break the wall.
• Damage reduction: if your mining damage is equal to or lower than the damage reduction, you deal 0 damage (the game tells you your mining damage is too low). Blocks with 9,999,999 reduction can't be broken.
• Raising mining damage: pickaxes (base values in the best pickaxe rankings), the mining skill (+1 per level, +100 at Lv.100), and armor, accessories and food with mining damage. Upgraded values are on the maximum mining damage page.
• Mining skill XP: you get 1 each time you deal 12 or more damage to a wall in one hit. Hitting several tiles at once with a sledgehammer still gives at most 1 per swing.
• Ground health: blocks placed as ground only have health, and you dig them with a shovel's digging damage.
