You have 2 uses of the Dueling Adjustment feature. 

Dueling Adjustment: This ability can only be used when your character has A) already been damaged by the creature attacking you or B) failed a previous Saving Throw against a spell made by the creature in question. As a reaction you can activate this ability. Using this ability will cause the attacker to reroll their attack roll, or give you advantage on your saving throw for the spell or spell effect.
