Dungeons & Dragons 5e Element 133 Class Feature: Mountain: Giant's Havoc

You continue increasing your strength transforming you into a hulking force of destruction. You may increase your Strength ability score by one. In addition, you gain the following abilities:

Crushing Hurl. When you make a successful ranged attack with a thrown weapon using Strength, you can add your Rage Damage bonus (or +3 if you do not have the Rage feature) to the attack’s damage roll.

Giant Stature. Your reach increases by 5 feet, and if you are smaller than Large, you may choose to become Large, along with anything you are wearing. If there isn’t enough room for you to become Large, your size doesn’t change.
