Taught to advanced gladiators who show talent for using one handed melee weapons and have a high level of mobility

Focused Strike. Once per turn, when you make a weapon attack roll against a creature, you can cause the attack roll to have advantage. If the attack hits, you roll a d8 and add the number rolled as a bonus to the attack's damage roll. You can use this benefit a number of times equal to your proficiency bonus, but a use is expended only if the attack hits. You regain all expended uses when you finish a long rest.

Rapid Move. A number of times equal to your proficiency bonus, when using a weapon attack and wearing only light armor, you can make an additional move of 5 feet to close with an enemy, the speed of this movement gives any enemy other than your target/targets you attack, disadvantage on melee attack rolls on you. This ability is reset by taking a short rest.
