Feats

Feats are properties a creature can choose to gain when leveling up. Usually, certain levels will offer a choice between two points of Ability Score improvement, and choosing a Feat instead, though some Feats also bring a single point of Ability Score improvements with them.

Athlete	Increase Strength or Dexterity by 1, to a maximum of 20. When you are Prone, standing up uses less movement.
Defensive Duelist	When attacked with a melee attack, use your reaction to increase your Armour Class by 2, potentially causing the attack to miss. Prerequisite: you must be wielding a Finesse Weapon with which you are Proficient.
Dual Wielder	Gain a +1 bonus to Armour Class while wielding a melee weapon in each hand. You can use two-weapon fighting even if your weapons aren't light.
Great Weapon Master	When an attack with a Melee Weapon scores a Critical Hit or kills a creature, you can make another Melee Weapon Attack as a Bonus Action that turn. When attacking with Heavy Melee Weapons you are Proficient with, attack rolls take a -5 penalty, but their damage increases by 10. (Toggleable Passive Effect; see Great Weapon Master: All In.)
