So, I’ve been considering using some sort of Wealth rules.
You’d have a Wealth rating just like a Skill. At chargen, you can buy it like any skill. After chargen, you can only change it with a narrative justification. Or double XP. Or somesuch.
Instead of a cost, every item has a Cost Rating similar to the Rarity Rating (1-10, difficulty is halved and rounded up). You’d still use Rarity Rating to know if you can even find an item, before buying it.
When you want to buy something, you roll Wealth against difficulty. Success means you bought it. Failure means you didn’t. Treasure would be handed out as free Boosts. (So the goblin king’s hoard has 10 Blue Dice to be split amongst the group. Note on character sheet. When you want to get something, add 3 Blue Dice, mark it off, etc.)
Obviously, this would require some thought with regards to the Negotiation skill.
Thoughts?
