XP Cards with Added Effects!
Requires the Cypher System Rulebook from Monte Cook Games.
The Cypher System encourages the use of XP in many different ways, but it can be easy for players to fall into a rut. Whether they always reroll failures in combat, or refuse to spend XP on anything except tier upgrades, these habits can make it easy to treat CS games as if their goal was to reach max tier as soon as and as smoothly as possible, and ignore the fact that XP can be used to integrate player characters into the game world through the creation of NPCs, jobs, titles, and homes.
UXP cards offer a twist on standard XP spending rules, providing bonuses and penalties to push players into spending XP in a greater variety of ways. You could just replace the standard XP deck with these cards, and hand them out randomly, but they are perhaps best used by a GM who wants to, for example, discourage one person from spending all their XP on rerolls, while another player can be tempted into buying their character a day job to offset their superheroing expenses.
