To make treasure a bit more interesting to find and collect, there are XP rewards for collecting Sets of items.
"Set collecting as a game mechanic is neither thematic or interesting on its own. It’s only interesting when there’s hidden knowledge (poker), competition for similar resources with a penalty for not getting them (rummy) or a cost to collecting the set (ticket to ride)"
Rules
The public list contains the bonuses for acquiring a complete set.
Individual items may be sold to merchants and experience gained for the amount they sold for (as usual).
Individual items may be sold to other players and experience gained for the amount they sold for. Extortion allowed. Only the original owner of the item (the person who picked it at treasure distribution) may gain experience points for items sold this way. There is no benefit to cyclically selling the item back and forth within the group.
Any incomplete set can be completed by a character by turning it into the GM. They keep the items and the set is marked as completed.
When a set is turned-in, the collector receives experience equal to their total value, plus the bonus multiplier, plus any bonus effects for as long as they keep the set.
The experience granted for the set item is subtracted from the other players experience point totals. This does not cause a loss of levels, but does increase the experience point required to reach the next level.
If a set is completed and experience received, and it is then sold or lost, the character loses the experience gained from the set (though if sold, they do receive the base gold piece value, without the multiplier value). The set becomes incomplete again.
Personalized set lists exist for different classes, locations, or rumors.
Example:
Eda collects five different gems worth 100gp, 200gp, 300gp, 400gp, and 500gp. They decide to "turn-in" the set "Any 5 gems of the same type and quality: 2x" and gain 3,000xp (1,500gp value x 2 set bonus). Eda's three other party members lose 1,000xp each.
Eda later decides so sell the gems for cash. They lose the set's 3,000xp but gain 1,500gp for the gem sale (and thus 1,500xp). They end up with the same 1,500gp and 1,500xp they would have had in the first place.
