"only fires once" meaning each pillar must be mined and replaced to fire again or is useless entirely after a single use? Is there a cool down on use? What does this mean?

Sounds good but not knowing what it actually does makes it seem as sketchy as some of mods that just say "random" as their description.

Why would it only ever fire once?

"only fires once" <-- that's why! I'm asking what that mechanic specifically means because it can mean only once ever, to only once to per day, to only once every few seconds... it's vague.

A vague description on a mod from an author that just flooded the mod portal with mods is not exactly showing confidence. Nor does it deserve confidence or a download.

I asked for a better explanation cause it sounded like it COULD be interesting but if all I am going to get is backlash then obviously this is a piece of garbage mod and I wasted my time!

Test it.

A lot of Factorio mod authors don't speak English as their first language and expecting perfect grammar from them is a bit ridiculous.

You're being rude.

Considering you can go to a very professional website in English linked by this mod author that is a BS argument. A statement of "fires once" is by definition just that: firing once, ever! So when asking for clarification on that and how it actually works and refusing to download until getting a more definitive explanation of how this mod works is well within my right. Just as it is well within this author's right to refuse to post any more mods.

After all the copied mods and sketchy mods that appear here and on the forums you would have to be an idiot to just trust anybody enough to download their mod.
