I had an idea for a new minigame for one of the kingdoms , which I thought could be good fun.
It would basically be a gambling machine of some sort, like a one-armed bandit or something. Where you can win traitstones.
You would put in one of your existing traitstones and pay gold to have a spin, with a chance of winning multiple copies of the traitstone that you put in. This could be overpowered as a device for farming traitstones, so it would have to cost a fair amount of gold and have relatively low chances of winning numerous copies of your traitstones. Below is my guess at what might be fairish chances of winning & gold costs to play.
From one spin:
50% chance: x1 traitstone (ie, you don’t win, you just get the traitstone you put in back)
30% chance: x2 traitstones
15% chance: x3 traitstones
4% chance: x4 traitstones
1% chance: x5 traitstones
0.1% chance: x10 traitstones
The gold cost for each spin would vary depending on the rarity of the traitstone you put in:
Minor: 1,000 gold per spin
Major: 5,000 gold per spin
Runic: 20,000 gold per spin
Arcane: 50,000 gold per spin
Celestial: 100,000 gold per spin
This would act as another way of targeting specific traitstones you require, basically buying specific traitstones for gold. Also this would be a fun gold sink for those players with a lot of gold and not much to do with it. Maybe you could also do it with troop cards as well, same principal , a chance to win additional copies of your existing troops. If it seems too ‘cheap’ to do this this with gold, especially for the rare traitstones, then maybe it could cost glory or gems to have a spin.
I’m sure this could be fun and work fairly with the correct chances of winning and gold/glory/gems costs to play.
