1- The Alchemist. What does it do? combine 2 identical buffs into one of a higher grade.
Max level of improved buff:5(?) To get the next tier of buff you need to have 2 (+ some other resource maybe?) of that grade. So for a say lvl 1 fishplatter you need 2 regulars, for a level 2 you need 2 lvl 1's etc etc. Time would just be double that of the original buff. (Which is why the extra cost in resources, maybe Saltpeter? Or a new one? dunno but I am sure it can be figured out)
2- Geological Survey station. Would have lvl 1-5 upgrades for each resources to decrease time and maybe increase amount of the resource found. aka 1-5% for each level (whcih needs to be researched at X cost of X resource) The increased amount refers to the Mine or Quarry. So instead of whatever it you find in that quarry or mine spot it will be increased by 1-5% depending on your upgrade level
ALSO!!! Would include a menu/slider to send Geo's to survey the same resource (So if you wanted to find Iron you could simply use the slider to send how many you want or a menu similar to sending generals to adventures, latter probably better due to skills)
3- Adventurers guild. Basically The same as the previous one. But of course it would include upgrades for decreasing time by 1-5%, increase amount of the resource found by 1-5%,increased amount of Map fragments by 1-5% and so on. Would also have a menu or slider but then for sending them on resource/ adventure searches.
This is basically a rough idea. But skimming through several posts I do tink it might be interesting enough for people.
