Primal Vigor

Your body is a conduit for the raw, untapped lifeforce of the ancients. You gain the following benefits:

• Your Constitution score increases by 2, as does your maximum for that score.
• You can cast enlarge/reduce without using a spell slot or material components, but you may only target yourself, and you may only choose the "enlarge" option. Wisdom is your spellcasting ability for this spell. Once you cast the spell this way, you can’t cast the spell in this way again until you finish a short or long rest.
