12. The Collection of Knickknacks - Invariably, someone at my table decides that their character will be keeping a collection of knickknacks. What these knicksknacks are varies from campaign to campaign, but it is often something extremely mundane (a copper from every town they visit, a tooth from every goblin they kill, etc.). These knickknacks serve no real purpose other than to exist, but the characters will do alarmingly stupid and amusing things in their attempts to acquire/hold on to their prized collections.
