The Verdant Heart

This pulsing, mossy stone of unknown origin glows with the light of life. All around the bearer; plants thrive and prosper, with acorns sprouting into saplings and saplings into oaks even as the Verdant Heart passes by.
Any wood or finest that the hearer is within counts as very difficult terrain as long as the character remains wholly within the terrain feature. In addition, the bearer gains +1 to cast spells from the Lore of life.
