Thunderbird

You have trained to fly in heavy metals, using their electrical conductivity to empower your martial ability. You gain the following benefits:

• Increase your Strength or Constitution score by 1, to a maximum of 20.
• You can use your Flight trait even when you're wearing medium or heavy armor.
• As a bonus action while you aren't touching the ground, you can channel the power of the storm into a weapon you are holding. For the next minute, your weapon attacks with this weapon deal an additional 1d6 lightning damage on a hit. Once you use your bonus action in this way, you can't do so again until you finish a long rest.
