Aotran Tseketon Thunderbird

You are a chosen warrior of the Mother of Storms. You gain the following benefits:

• Increase your Constitution or Wisdom score by 1, to a maximum of 20.
• When you deal lightning or thunder damage to a creature with a weapon or spell attack, you can reroll any roll of 1 on the lightning or thunder damage dice, but you must use the new roll, even if it is another 1.
• If a spell has the sole purpose of returning you to life (but not undeath), such as raise dead, a caster does not need  material components to cast that spell on you.
