Two Handed Master

You gain the following benefits:

• On your turn, when you roll a 19 or 20 with a 2-handed melee weapon, you can make one melee weapon attack as a bonus action.

• Before you make a melee attack with a heavy weapon that you are proficient with, you can choose to take a - 5 penalty to the attack roll. If the attack hits, you add +10 to the attack’s damage.
