Giant Foe 2014
Your experience fighting giants, such as ogres, trolls, and frost giants, has taught you how to avoid their deadliest blows and how to wield mighty weapons to better combat them. You gain the following benefits:
Increase your Strength score by 1, to a maximum of 20.
If you normally have disadvantage on attack rolls made with weapons with the Heavy property due to your size, you don't have disadvantage on those attack rolls.
When a giant attacks you, any critical hit from it against you becomes a normal hit.
Whenever you make an Intelligence (History) check related to the culture or origins of a giant, you are considered proficient in the History skill and add double your proficiency bonus to the check, instead of your normal proficiency bonus.
