Well.. I've thought of another Suggestion,
What about a training Space.. Its a place where we can rent (using toks or whatever), to add permanent stats,
up to 5 stats (or Whatever), on a decided stat, so vit/str/int/dex/agi/luk,
But limited to 3x usage.
So inside the space, there is going to be a totem, with a hp of 1m, or whatever, and our damage is only 1, den you have to hit it. until the totem dies.
then you will get 1 stat each time the totem dies. so if its up to 5 stats, there will be 5 totems. if they don't kill all totems, before they go out, they cant go back inside the same rooms, and their entrance quota will still be deducted by 1.
