I Know Your Flaws
From NsdWiki
Combat Trump
Expoint Cost: 2
Because of your extensive study and/or experience in dealing with (and likely fighting) a particular race of people, you have also learned where the flaws in their defense are located. Pick a humanoid race (listed in Chapter 5): you receive a +2 bonus to Damage Rolls against members of that race. You can take this trump more than once, each time for a different race.
