Destined Foe

10th-level Gladiator Feature

Your show skills are improved to the point that you know the maximum excitement comes, from a one-on-one fight. As an action, you may choose a creature within 20 feet to become your destined foe. While fighting a destined foe, you may add your charisma modifier to your attack rolls, damage rolls, and saving throws, as well as gaining a bonus to your AC equal to half your proficency bonus (rounded down).

If either you or your destined foe are damaged, healed, buffed, or otherwise affected by a different creature, then the one-on-one is broken. Afterwards, you subtract your charisma modifier from your attack rolls.

Once a minute has passed, deathmatch activates.
