Because you don't like to kill aliens, here is a mod to build their artifacts.

1 Alien artifact is given by :

• 15 Alien science pack
• 10 water
• 5 Sulfuric acid
• 1 Processing unit
• 30 sec

To get this receipe you will need to get "Alien Science 2"

• 250 of each science pack
• Requires "Alien Science"

Important : this mod require "Alien Science" mod

Water and Sulfuric Acid, that means you have to build it in a Chemical plant, right?

I've seen recipes built in assembler that need fluids. Though I've not seen one that uses more than one at a time.

It's impossible to build a recipe that needs two fluids in an assembler because it has only one input. In fact, no recipe with 3 fluids can be built because even the refinery and chemical plant have only 2 inputs.

Exactly, only the chemical plant, or oil refinery can accept 2 fluid inputs.

if you wanted something to be able to use more than 2, you'd need to make a costom factory for it.

Ah, thanks for explanation. Didn't realize that limitation

I see a major problem here:

With Productivity 3 modules, you can make 1.2 Alien Artifacts out of 10 Alien Science Packs (If productivity modules apply to the recipe, not tested) and take those to make 1.2*10*1.4 = 16.8 Alien Science Packs at the expense of 5 Sulfuric Acid and a Processing Unit, letting you produce an Alien Science Pack for:
5/(16.8-10) = 0.735... Sulfuric Acid
1/ (16.8-10) = 0.147... Processing Units
in the long run.

That completely destroys the balance of the Alien Science Mod you have as a Dependency.
If you have other mods with better modules installed, it's even worse.
You might want to increase the amount of Alien Science Packs needed to at least 17 to fight such exploitation at least in the vanilla case. Or do something about the cyclic dependency or the applicability of productivity modules to both recipes.

I think a 15:1 ratio of purple packs to artifacts is a reasonable ratio to prevent the player from creating extra artifacts out of thin air. At >50% productivity you're paying copious amounts of energy & time anyway.

New version with 15 alien science pack required.
