Weapons and Tiers

By ScotUpdated

Tactical Quick Answer

CastleMiner Z weapons come from mining and crafting, never loot drops, so your damage scales with the materials you pull out of the ground. Pickaxes run six tiers from Stone through Copper, Iron, Gold, Diamond, and Bloodstone, while weapons and ammunition use four. Space Goo and Space Rock sit outside that ladder as the ingredients for energy weapons. Skip Copper tools, rush the Bloodstone Pickaxe, and save high tier ammunition for dragons and aliens.

Weapon progression in CastleMiner Z revolves entirely around the game's mining and crafting system. You do not find better weapons as random loot drops. Instead, you mine increasingly rare materials to craft stronger weapons that deal more damage and possess higher durability.

Material Tiers​

Your offensive capabilities scale directly with the materials you pull out of the ground. The game uses six tiers for pickaxes and four for weapons and ammunition, running Stone, Copper, Iron, Gold, Diamond, Bloodstone. Space Rock and Space Goo sit outside that ladder: they are energy-weapon ingredients, not a seventh tool tier, and there is no Space Rock pickaxe.

Stone and Copper (Tiers 1-2)​

Stone tools are the very first thing you craft. They break fast but get you into caves. Copper is the next ore you find, but Copper tools are a trap. They degrade so quickly that you spend more time replacing them than progressing. Skip Copper tools entirely and save all your Copper for crafting ammunition.

Iron and Gold (Tiers 3-4)​

Iron and Gold make up the reliable mid-game tier. Iron weapons are easy to mass-produce and durable enough to survive several nights. Gold weapons fire faster and deal slightly more damage, but the ore is harder to find in large quantities early on. Use these materials to craft your first shotguns and assault rifles.

Diamond and Bloodstone (Tiers 5-6)​

Diamond and Bloodstone represent the late game tiers. A Gold pickaxe is the lowest tier that can mine diamond, and Diamond or Bloodstone picks work too. You then need a Diamond pickaxe to mine bloodstone. Bloodstone generates in the deep underground and makes up much of the Hell biome terrain (roughly 40 blocks down, or about 3,400 blocks from spawn laterally). Bloodstone weapons are powerful and durable. A Bloodstone assault rifle or knife cuts through most standard zombie hordes and gives you a fighting chance against dragons.

Endgame Materials: Space Rock and Space Goo​

Space Rock and Space Goo are the rarest materials in the game, found only at Alien Crash Sites. Mining them triggers localized alien spawns, so come armed with Bloodstone weapons at minimum.

Space Rock is harder than Bloodstone and needs a Bloodstone Pickaxe to mine. Space Goo is the one a Laser Sword can also handle. The two materials divide by purpose: Space Goo crafts the energy guns themselves, while Space Rock makes laser bullets. Both also serve as blast-proof building blocks.

:::info Laser colors are not a power ladder The color of an energy weapon comes from the trim metal you build it with, not its strength. Iron makes red, copper green, gold pink, and diamond blue. A Blue Laser Pistol costs 2 Space Goo and 3 Diamonds against the Red's 2 Space Goo, 2 Diamonds, and 1 Iron, so blue is the diamond-expensive option and not a weaker one. Players who call the "Red Laser" the top tier are describing the cheapest trim. :::

The Laser Sword deserves a mention of its own. Built from 4 Space Rock plus 4 bars of your chosen metal, it works as both a melee weapon and a mining tool.

Weapon Classes​

CastleMiner Z divides weapons into clear classes, each suited for a different combat range.

  • Knife: Your basic melee weapon. A bloodstone knife is surprisingly lethal and saves you ammunition.
  • Pistol: You spawn with one in every mode, so this is your actual starting firearm, not the knife alone.
  • Submachine Gun: Fast-firing close-quarters option that bridges the gap before rifles.
  • Assault Rifle: A versatile, all-purpose weapon. It performs well at medium range and handles single targets effectively.
  • Rifle: Delivers massive single-target damage from a distance. Players usually call this the sniper. Use it to pick off dangerous enemies before they reach your base.
  • Shotgun: The best choice for early game defense. A shotgun blasts apart zombies at close range and provides excellent crowd control.
  • Light Machine Gun (LMG): Features a huge magazine size and fast fire rate. Perfect for holding the line against massive swarms.
  • Explosives: The RPG plus Grenades, TNT, and C4. Your answer to boss tier enemies and large groups, at the cost of expensive ammunition.

Your Axe, Pickaxe, and bare hands also function as melee options in an emergency.

Ammunition Management​

Guns are useless without bullets. You must manage your ammunition carefully, especially in Endurance mode. Running out of bullets during a night raid or a dragon attack leaves you completely defenseless. Always carry a strong melee weapon as a backup.

warning

Crafting bullets requires a constant supply of materials. Do not waste diamond or bloodstone ammo on weak surface zombies. Use iron or copper bullets for low tier threats to save your high tier ammo for dragons and aliens.

Tool Durability​

Not all pickaxes are created equal. The durability curve in CastleMiner Z is heavily skewed toward the top end.

  • Stone and Copper: Break extremely fast. Copper tools are a net-negative investment. Skip them.
  • Iron and Gold: Reasonable durability for mid-game mining. Gold is also the cheapest pickaxe that can mine diamond.
  • Diamond: Strong and long-lasting, but still degrades over extended mining sessions.
  • Bloodstone Pickaxe: The best tool in the game, crafted from 10 Bloodstone blocks and 3 Diamonds. It mines other blocks around four times faster than Diamond and is the only pickaxe that can handle Lava and Space Rock. It is not unbreakable, though: expect roughly two to three hours of real playtime before it wears out.
tip

Rush the Bloodstone Pickaxe as your top priority once you reach the deep underground. It will not last forever, but it mines fast enough that you spend far less time replacing tools, and it opens up Space Rock.

Frequently Asked Questions​

What is the best weapon in CastleMiner Z?

Energy weapons sit at the peak of the technology tree. You craft the guns from Space Goo and their bullets from Space Rock, both found at Alien Crash Sites. Their color reflects the trim metal used, not their power, so red is not a higher tier than blue.

How do you craft a Bloodstone Pickaxe?

You need 10 Bloodstone blocks and 3 Diamonds. It mines roughly four times faster than Diamond and is the only pickaxe that handles Lava and Space Rock, though it still wears out after about two to three hours of use.

What pickaxe do I need to mine Bloodstone?

A Diamond pickaxe. To mine diamond in the first place you need at least a Gold pickaxe, not an iron one. Space Rock is harder still and requires a Bloodstone Pickaxe, while Space Goo can also be mined with a Laser Sword.

Are Copper tools worth crafting?

No. Copper tools degrade so quickly that you spend more time replacing them than progressing. Save all your Copper for crafting ammunition instead.

Which ammunition should I use on regular zombies?

Use iron or copper bullets for low tier threats. Save diamond and bloodstone ammunition for dragons and aliens, since crafting bullets requires a constant supply of materials.
