Rune Modules

Rune Modules are etched runes you slot into machines to make them faster, more efficient or more productive. A Rune Beacon shares its modules with every machine around it. Modules arrive in Epoch 4 with the research Rune Crafting.

Modules

Three kinds, each in three tiers. Values change the machine's base speed and energy use.

Module	Speed	Energy use	Productivity
Rune Module Speed MK1	+20 %	+50 %	–
Rune Module Speed MK2	+30 %	+60 %	–
Rune Module Speed MK3	+50 %	+70 %	–
Rune Module Efficiency MK1	–	−30 %	–
Rune Module Efficiency MK2	–	−40 %	–
Rune Module Efficiency MK3	–	−50 %	–
Rune Module Productivity MK1	−5 %	+40 %	+4 %
Rune Module Productivity MK2	−10 %	+60 %	+6 %
Rune Module Productivity MK3	−15 %	+80 %	+10 %

• Effects of all modules in a machine (and of beacons around it) add up.
• Speed and energy use never drop below 20 % of the base value. Two Efficiency MK3 already reach that floor.
• Productivity collects bonus with every finished craft. Each time it reaches 100 %, the machine makes the result twice. If the extra result does not fit into the output, it is lost, so keep the output emptied.
• Productivity works on every recipe the machine can make, and on drills.

Which buildings take modules

Building	Slots
Fabricator T2	2
Fabricator T3	4
Electric Furnace	2
Auto Drill	3
Oil Processor	3
Chemical Plant	3
Big Stone Golems Refinery	2
Goblin Research Center	2
Golem Research Center	2
Rune Beacon	4

Other buildings have no slots. In the research centers only the speed part counts.

Putting modules in: hold a module, crouch and Use the building. One module goes into the next free slot. Grabbers can also feed modules into a building, one per free slot.

Taking them out: crouch and Use the building with an empty hand while its output slot is empty. The module inserted last comes out first. Breaking the building gives the modules back.

Rune Beacon

	Rune Beacon
Epoch	4
Unlocked by	Rune Crafting 2
Size	3 × 3
Energy	480 kW electric
Slots	4
Range	4.5 blocks
Recipe	20 Advanced Circuit + 10 Rune Slate + 10 Steel Plate + 10 Copper Cable

• The beacon passes its modules on to every machine within 4.5 blocks, at half their effect. A Speed MK3 in a beacon gives +25 % speed and +35 % energy use to each machine in range.
• It only works while it has power. Without power its modules do nothing.
• Several beacons can reach the same machine; their effects add up. Beacons do not affect other beacons.
• Use the beacon to open its window. Click a module in your inventory to put it in, right-click a slot to take that module out. The window shows whether the beacon has power.

The beacon also boosts crafting machines, furnaces and drills that have no module slots of their own. A typical layout puts a row of beacons between two rows of Fabricators, so each beacon serves both rows.

Recipes

All modules are made in a Fabricator. Times are at speed 1.

Module	Unlocked by	Epoch	Recipe	Time
MK1 (any kind)	Rune Crafting	4	5 Advanced Circuit + 5 Electronic Circuit + 2 Rune Slate + 1 Golem Core	15 s
MK2 (any kind)	Rune Crafting 2	4	4 MK1 of the same kind + 5 Advanced Circuit + 5 Processing Unit + 2 Rune Slate	30 s
MK3 (any kind)	Rune Crafting 3	5	5 MK2 of the same kind + 5 Advanced Circuit + 5 Processing Unit + 5 Rune Slate	60 s

Rune Slate comes from the Chemical Plant (1 Stone Brick + 2 Gold Wire + 5 Sulfuric Acid, research Rune Etching), see Oil Processing. Golem Core comes with Golemcraft, see Golems.

Tips

• Put Speed modules into bottlenecks and Efficiency modules into machines that run all the time.
• Productivity pays off most on expensive products, but it costs a lot of power. Check your grid in the power window.
