NsdWiki:Trump Cost

The bonuses a Trump conveys should be compared to the bonuses that can be achieved by other means.

• It costs 5 Expoints to purchase a new Ability point. A character can use an Ability point in many different tasks.
• It costs 2 Expoints to purchase a rank in a skill (including magic schools and weapon skills)

For example, a Trump that inflates a character's attack roll should consider that it takes 2 XP to buy another rank in the weapon skill.
