A multi-layered jacket made of the hide of a terrible Wurm. It is supple and soft, yet retains many of the properties of the hardy beast it once belonged to.

This armor regenerates all damage done to it so long as it is not reduced to shreds. You have resistance to acid and bludgeoning damage while you wear this armor.

Verdant Heart. A Wurm never truly dies, no matter how it is slain or destroyed. As an action, you may venerate the Wurm that is the Jack and it will share with you a portion of its power. Your size doubles in all dimensions, and your weight is multiplied by eight. This growth increases your size by one category-- from Medium to Large, for example. If there isn't enough room for your size to double, you attain the maximum possible size in the space available. Until the spell ends, you have advantage on Strength checks and Strength saving throws. Your weapons also grow to match your new size. While these weapons are enlarged, your attacks with them deal 1d4 extra damage. This effect lasts for 1 hour.

Once used, the armor's Verdant Heart property can't be reactivated until the next dawn.

Made from tough but flexible leather, studded leather is reinforced with close-set rivets or spikes.
