You have slain the Iron Wyvern. This is a feat that will stay with you for ever.

• Increase your Strength by 1, to a maximum of 20.
• You gain the heavy impact ability. This ability grants you the opportunity to increase the weight of your weapon attack, increasing the damage by 1D8 once a day.
• Once per day, you can release a primal roar, forcing each creature of your choice within 30 feet of you to make a Wisdom saving throw (DC 8 + your proficiency bonus + your Charisma modifier). A target automatically succeeds on the save if it can’t hear or see you. On a failed save, a target becomes frightend of you for 1 minute. If the frightend target takes any damage, it can repeat the saving throw, ending the effect on itself on a success.
