Brutish Attacker

You use your own weight and the weight of your weapons and armor to fuel your vicious attacks. You must be using a weapon with the heavy property to use any of the benefits of this feat. 

You may use one of the following abilities once per turn:

• Before making an attack roll, you can choose to suffer a -5 penalty to the roll. Doing this gives +5 to the damage roll, and if the damage dice for this attack read lower than your strength modifier, reroll them.
• You can fully commit yourself to a single, massive attack you give yourself advantage on one attack roll and a +5 bonus to damage but you cannot take reactions until the start of your next turn and you cannot use the extra attack feature and this one in the same turn.

As a bonus action, you may give yourself +3 bonus to attack and damage rolls for 1 minute or until you are incapacitated. You can use this feature once per long rest.
