Grown through druidic magic, this armor is attuned to nature and reacts to the wearer’s vitality. While wearing living wood armor, you can use your reaction to gain temporary hit points equal to your proficiency bonus when you are reduced to half your maximum hit points or lower. These temporary hit points last until the end of your next turn. Living wood armor costs the base price of the armor plus 1.500 gp. Only light or medium armor with the Natural Materials property can be made from living wood.
