Destructive Strength (5e Feat)
From D&D Wiki
Prerequisites: Strength 13 or higher
You increase your strength by 1 to a maximum of 20
Whenever you deal damage using a weapon with the strength attribute, you add double your strength modifier.
Your can put extra force into your attacks, driving your weapon deeper into your foes to maximize your damage. When you hit a creature with a melee weapon but before you roll for damage, you can choose to roll the maximum value possible instead of rolling it normally the attack's damage. For example, if a 4th-level character were to roll 2d6 damage, they could choose roll a 12. You can use this feature a number of times equal to your Strength modifier, regaining all expended uses when you finish a long rest.
