• Tier 1 A single item worth 100 dinars or more, or a nonconsumable rare magic item
• Tier 2 A single item worth 1000 dinars or more, or a nonconsumable very rare magic item
• Tier 3 A single item worth 5000 dinars or more, or a nonconsumable legendary magic item
• Tier 4 A single item worth 50000 dinars or more, or an artifact

For example, if a level 2 party finds a gem worth 100 dinars, everyone gets 60xp.

In addition, whenever you find treasure (whether it meets the criteria on this page, or is of lower individual value, such as coins), you get the XP from the monsters that were guarding it. So let's say a level one, a level two, a level three and a level four character sneak past a skeleton (in our ruleset a 50 xp enemy) to find a 100 dinar value gem. They each get (50/4)+380 = 392 xp. Joy!

Every character doesn't have to make it to the treasure room in person. As long as you are part of the same expedition, part of the same venture, present in the session, and alive, you qualify. Absent players, dead characters, or characters who stayed in town while the other characters went to the dungeon get zilch. Merely unconscious characters do get a full share.

Alternatively, if you are using a domain game system, such as Worlds Without Number, when you are level 10 to 16, Tier 3 items give one domain treasure and Tier 4 items give 1d4 domain treasure. When you are level 17 or higher, Tier 4 items give 1 domain treasure. This is instead of character XP.

Some NPCs have it in their contract that they don't get any XP, others that they get full. Often enough the deal is that they get a halfshare of XP, calculated as follows:

Each halfshare of monster XP is the total monster XP divided by (Number of NPCs + twice the number of PCs). PCs get two halfshares.

So in the skeleton sneaking example, if two heroes would've been halfshare NPCs, then instead of dividing the 50 by four it would've been divided by 6 (2×2+2 = 6) and each player character getting two such halfshares. NPCs also get half of items' worth, so the NPCs would've gotten 198 and the players would've gotten 396. Slightly more joy!

A.k.a. making an honest living.

For every five dinars over the threshold you earn per month you get 1xp.

So if you are a level 5 character who earn 4000 dinars by trading, you get (4000-650)/5 = 670 xp. Your fellow party members don't get anything.
