I am stealing this from a great new Gumshoe game called Swords of the Serpentine by my friend Kevin Kulp. What are the three things your hero would say to answer this question? Unlike in “Conan the Barbarian,” there is no wrong answer.
The point is to give yourself, the DM and other players a bit of a thumbnail sketch of who you are.
These can change as your character develops
Being tested in single combat // Besting multiple opponents // Seeing the horror in their eyes when they realize they’ve made a mistake
Wealth & comfort // Privateering, profiteering & orienteering // Living to fight another day
Salt on your beard // Grog in your gut // A vigorous rut with my lady-wife
You can tap these like mini-hero points for +X circumstances bonuses here and there, either to attack, or for bonuses to damage or skill checks, etc. You just have to be creative and remember to ask. If your character does or says something particularly cool related to one of your three WIBILs (that is to say, totally in character), I may award Hero Points (if I remember or am reminded!)
You can also stack them with Hero Points and Plot Twists to do something narratively cool.
