So FATE doesn't seem to have anything on gears, probably because it's intended for magical items.
So I'm homebrewing a system for it.
My idea so far is that buying an equipment work like gacha. You pay the money, you get randomized stuffs. You have a finite amount of rerolls depending on the number of people doing the shopping and their skills.
Everyone roll Rapport as the default skill (they can use other social skills if they can convince me to, but that's neither here nor there). A person who isn't there /can/ participate in the rolling in certain special circumstances (like knowing the shopkeeper). If they got -1 or lower they get no rerolls, while if they get positive rolls the amount of rerolls for the goods they receive is the roll result + 1.
You pay a variable amount to determine the tier (1 is 1 fate die, 2 is 2 fate dice and so on) of the equipment, which is then used to determine its quality.
-2 - Terrible: Has a Class 2 Negative Effect.
-1 - Poor: Has a Class 1 Negative Effect.
0 - Mediocre: Boring.
1 - Adequate: Has Class 1 Positive Effect.
And so on.
The effects are triggered when you roll 3 lower than your opposition when they're negative, and when you roll 3 higher than your opposition when they're positive.
I'm not sure if this is too complicated. Also, I will write a table for effects, and I would appreciate if you guys have ideas for them and PM me about it. Please also note that the effects are supposed to be *minor* and are supposed to compound on the situation caused by the roll. For instance, a Class 2 Negative Effect should only be something like the weapon jamming.
