I'm assuming that fortune dice bought for characteristics are used any time that characteristic is is tested right? So buy a fortune die for strength and any time you test strength or a skill derived from strength you get the die?
What about talents or career cards that give a die when you test a specific characteristic? Would that only be available when specifically testing the characteristic or even on skills that use the characteristic?
For example, the Tactic card Might Makes Right. When spending fortune on a "strength test" you get to convert Boons to successes. So is this only valid on generic strength tests or could you also use it when testing Weapon Skill?
