Historical Perspective Feat 14

General Skill
Prerequisites legendary in Society

Let’s learn about where these came from. When you attempt a check to learn about a creature using a non-Society skill check and succeed, not only do you learn about its weakness as normal, but the creature gains weakness 10 to all damage till the end of your next turn. You can only do this to a creature once per day, but you can attempt this against each creature you encounter. If you encounter multiple of a same creature, all creatures of the same type only gains weakness 10 to all damage till the end of your next turn, and you can not attempt this against another of the same creatures again that day.
