Second Chance

Prerequisite: Halfling
Fortune favors you when someone tries to strike
you. You gain the following benefits:
•At level 5, increase your Dexterity, Constitution,
or Charisma score by 1, to a maximum of 20
•When a creature you can see hits you with an
attack roll, you can use your reaction to force that
creature to reroll. You can use this feature a
number of times equal to your DEX modifier.
Your uses reset when you finish a long rest.
