Band of the Elder

A simple headband woven from fine red and white silk intertwining with one another. While the attuned creature wears this band, its hit point maximum increases by an equal amount to their character level. When attuning to the item, or donning and doffing it, only the hit point maximum changes. If the current hit points exceed the hit point maximum, reduce the current hit points by an equal amount as the difference.
