Curse of Jealousy
This curse causes the affected to become notoriously jealous. Of everything. Your party member buys a new ring? You want one too. Your favorite NPC talks more with another character than with you? A scandal!
Here, you have all the freedom to go wild. Are you in a relationship with another character? Everything they do makes you jealous. Don’t have a relationship? No problem, you’ll find things to be jealous about.
This curse is especially suited for groups that play harmoniously and where you can rely on the fact that friction does not lead to conflict outside the game.
Curse of the Anime Hero
With this curse, you announce everything you do. This can be your attacks or specific actions that you must elaborate on or emphasize with iconic exclamations.
This curse is particularly nasty for rogues and characters who prefer to operate in secret. Imagine wanting to sneak up on someone but having to loudly announce that you are about to strike.
Experience shows that this is a type of curse that is at least partially still used afterward. Especially bards and barbarians seem to like it significantly more than some dungeon masters would like.
