Faerie Vines (Firbolg Racial Feat)

You call in one of the many favors you are owed by the natural flora of your world. Vines sprout at your feet and climb to surround and defend you. You gain the following benefits:

• Increase your Constitution, or Wisdom score by 1, to a maximum of 20.
• When you cast a healing spell, you can reroll any roll of 1 on the HP dice, but you must use the new roll, even if it is another 1.
• Whenever you cast a support spell, you can call on the Faerie Vines to protect you until the end of your next turn. While the vines are present, any creature within 5 feet of you that hits you with a melee attack takes 1d4 slashing damage.
