Explosives and rockets: the loud ones.

The Rocket Bench

The Rocket Bench is a Forge Bench with extra metal, and it needs the Anvil Age. Everything made at a Workbench or by hand can be made there too. Rocket recipes include the Rocket Bench, and the ship rockets need the Corelight Age (steel and titanium) or the Temper Age (steel).

Grenades

Hold a grenade and press the fire button to throw it. The throw carries it a few metres, and it bounces off what it meets until its fuse runs out.

Grenade	Harm at the centre	Blast radius	Fuse	Made from
Frag Grenade (2)	200	3.5 m	2.6 s	2 iron, 2 gunpowder
Impact Grenade (2)	150	3 m	bursts on landing, up to 5 s	2 iron, 3 gunpowder
Incendiary Grenade (2)	60	4 m	2.4 s, then sets alight what burns round it	2 iron, 2 sulfur, 2 charcoal

The harm falls off across the blast: full at the centre, a quarter at the edge, and none beyond the radius. Blocks in the blast take their share, and a block whose armour is spent is broken. An Incendiary Grenade sets fire to the blocks round it that will burn.

Land mines

A Land Mine (3 iron, 3 gunpowder and 1 copper, making one) is laid on the ground in front of you with the fire button. It arms 2.5 seconds after it is laid. Then it bursts when a creature or any other player's foot comes within 1.3 metres of it. Your own foot does not set it off, and it bursts at once if the ground under it is dug away.

• Harm at the centre: 340. Blast radius: 3.8 m.
• You can have up to 200 mines laid in a world.
• Mines must go on solid ground, and not in another player's claimed ground.

Hand rockets

The Missile Launcher is a handheld rocket gun (see Guns, bows and crossbows). Its rockets are made at the Rocket Bench (2 iron, 2 gunpowder and 1 plant fibre make two). A crafted rocket does 25% more harm than a rocket loaded from loose gunpowder. The rocket flies straight, at 75 metres a second, until it strikes.

Ship rockets

Ships and fighters carry racks of rockets for their missile pods and gunships. Two kinds are made at the Rocket Bench:

• Dart Rockets (2 steel, 4 gunpowder, 1 glass for two; Temper Age): homing rockets that lock onto a target. A craft carries up to 12.
• Heavy Rockets (4 steel, 6 gunpowder, 1 titanium alloy for one; Corelight Age): one big unguided rocket that takes a hull apart. A craft carries up to 4.

Load them into a craft by using them on her. Using the ship's rocket key fires darts at a lock, or a heavy rocket if you have one loaded and no lock. A docked fighter is refilled with darts in its carrier's bay.

Fireworks

Fireworks come from the Rocket Bench, four at a time, and burst in red, gold, blue or green. Each is made from a piece of gunpowder, a plant fibre and a pigment: red ochre for red, salt for gold, azurite for blue, malachite for green. Light one with the fire button and it rises 20 to 26 metres before it bursts. They do no harm. They are just for show.

Tips

• Impact grenades are the best for clearing a doorway: they burst the moment they land.
• Lay mines along a path that creatures use, and stand back while they arm.
• Stand well outside the blast: the harm reaches 3.5 to 4 metres.
• Iron and steel armour cut explosion harm. See Armour.
