What is the max resource on a planet? I have a 15x Mega Rich toxic mining production and I have a Toxic Purifier and it won't let me use it on that 15x planet. Is 15x the limit? Not sure if this is a bug.... thanks...

-TS...

It is, yes.

15X is the limit if you modify the planet with Terraformers, Toxic Purifiers, etc. There are planets out there that "naturally" already have higher outputs than this though; I believe they can go up to 48X. The limits have also been added in the last month or four, so it's entirely possible that there are planets that were modified past the 15X limit before Dan added in the 15X limit.

Actually, if you get lucky and get a planet with a certain starting point, you can go up to x16. Something to do with even numbers.

Ya if you get a world that has extremely rich mineral production when you start out and you only use the purifiers on it will be able to go from 14X to 16X. If you get one that starts out on very rich and go from there you will not. In order to get it so you can get the 16X you will have to use a terraformer on it before it gets to 15X. It can be at 13X when you use the terraformer and go to 14X then you can use a purifier and take it up to the 16X mark.

Just for your info 15X gives you a 575% increase in production where as 16X gives you a 600%

For me I have a 15X that has a mineral production count at 32 and it is giving me 432 minerals an hour. At the same time I have a 16X that has the same mineral production count giving me 448 an hour. So its up to you on what you want.

So there's this for toxic planets, Planet Data Optimizer for any planet (max x15 I would think as well), nothing for artifacts perm increase to planet. I get the Rogue LabPod that drops Planet Data Optimizer a lot more than the Blade Harvester, actually it's the most common rare that I encounter.

I wish I was you. I see Lazuli Factory Complex like they're going out of style! Looking at the list, there are many things I've never even seen!

Well there are some I don't think you can see past a certain rank, but mostly commons that are replaced with a similar NPC with higher stats (like Dark Velocitor -> Dark Warpers). Most matched probably can spawn regardless how high your rank. Rank 65 Sha'din Infiltrator is an uncommon that gets replaced with Rank 125 Sha'din Ambusher I think. I'm not sure how many item drops are unavailable after achieving higher ranks (without a corresponding higher level item on a higher rank NPC). I long for an artifact quality boosting item for planets, I don't know of any NPC drops that can do that.
