Ignore Pain

You are so used to getting hurt, pain has become more of an annoyance than a real issue. As a result you may push past your healthy limits and choose to add 2 to your strength, dexterity, or constitution modifier whenever making a saving throw or ability check, whilst inflicting 1d4 damage unto yourself in the process. Additionally, when you gain your first point of exhaustion, you ignore its effects until you gain 2 points, after which your lack of stamina will hit you all at once and the condition will act as normal.
