Other types of liquids and rain.

That would fit under the liquid elements category.

I put your first two ideas in, but i'm unsure about those two at the moment.
Swamp water would just be regular water right? What would be the applications of it?

I suppose ink could work... I just need more clarification on the idea.

 

I think Swamp water is just ascetic. Maybe it could spawn new mobs

I read through your posts and I didn't see Quicksilver (Mercury) be mentioned as conductive to electricity (which I assume will be added into the game at some point)

 

I was watching a thread about the Viscons and i thought Ferrofluid should be added.
It's a magnetic liquid, it can be crafted and is rarely found in industrialized areas.It's attracted by any metal blocks, it can be used in metal detectors.

 

Very well then. Adding it to the top.

 

lava is molten metal/rock and would be WAAAAAAAY too heavy, change that to sulphuric acid(like on Venus)

 

Just remember that this is a game. Raining lava could work, especially on volcanic planets with eruptions going on.

 

actually eruptions just fire lava and ash into the sky and scattering the land around it with just that, lava and ash
it would make no sense for lava clouds to exist

 

Well, there's raining fish. Don't believe me? Read the first post here:

So there might as well be a lava rain. Perhaps there could be lava-geysers which throw lava into the air, there it gets snatched up by super-strong wind(like it is in some planets) and gets carried upwards a little. A drop by drop it slips through the wind and starts falling downward in the form of rain. It doesn't turn into rock because the climate around it is too hot. This is just an example of how could it rain lava. Just be creative and you will find a way.

 

raining fish could only occur if there was a tsunami or something causing a giant splash sending the fish into the sky then onto land

 

There you have it! See? It is possible to logically explain almost any weird thing if you only put your mind into it!
Einstein himself once said:

"Logic will get you from A to B. Imagination will take you everywhere."​

 

but it would make more sense for sulphuric acid and not lava, that would incinerate you and/or your ship upon entering the atmosphere

 

I wonder how big is the target audience for this game is...because as an avid Dwarf Fortress player I hope there will be blood

 

I'm thinking of bleach. Not the show but the liquid.

Bleach is a crafting only item that can be used to purify things or be used in poison recipes.

 

I love the idea of the bioliquid, it could be something harvested for healthpacks and the like allowing us to devastate the natural environment for our own gains

 

Just thought of rubidium. It explodes on contact with water.

 

Chocolate rain? Naw, maybe something like mercury rain that poisons the water would be interesting.

 

Tay Zonday approves! nitrogen rain would also be nice - freezes you unless your under a roof

 

Why, yes. That would work too.

 

I have put in a link to an open source game that i got some of my ideas from, maybe this would help people to come up with even better ideas.

 

A couple more liquid ideas for you:

Living Gel - A thick liquid that comes in various colours. Harmless, but will occasionally start moving of its own accord! When Living Gel wants to move, it forms into a sphere and rolls to another convenient place that can hold it as a pool before settling again. If you are swimming in the gel when it does this, you will be carried along with it! Living Gel never appears as rain.
Energel - A thick fluid used to make energy cells. Your energy rapidly recharges while you are swimming through it. On planets where Energel occurs naturally, gel rain may occur after a hurricane or tornado. Energel is frequently found in large reservoirs in highly advanced structures.
