Your bond with the elemental might of giants grows, and you learn to infuse weapons with primordial energy.
When you enter your rage, you can choose one weapon that you are holding and infuse it with one of the following damage types: acid, cold, fire, thunder, or lightning. While you wield the infused weapon during your rage, the weapon’s damage type changes to the chosen type, it deals an extra 1d6 damage of the chosen type when it hits, and it gains the thrown property, with a normal range of 20 feet and a long range of 60 feet. If you throw the weapon, it reappears in your hand the instant after it hits or misses a target. The infused weapon’s benefits are suppressed while a creature other than you wields it.
While raging and holding the infused weapon, you can use a bonus action to change the infused weapon’s current damage type to another one from the damage type options above.
