Regolith Mantle [CARD] (Patreon)

Armor (half plate or plate), legendary (requires attunement)

A bulky set of stone armor that seems to be covered in perpetually flowing sand, though none ever falls to the ground. While wearing this armor, you gain an additional +3 bonus to your AC.

Terra Titan. While you are attuned to this armor, you can use an action to cause this armor to expand and reform itself into an enormous puppet made of earth and sand that encapsulates your being. You gain a number of temporary hit points equal to half of your current remaining hit points which last for 10 minutes. While you have these temporary hit points you gain the following benefits:

Your size becomes huge. If there isn't enough room for you to attain that size, you attain the maximum possible size in the space available.

You are not affected by difficult terrain, you cannot be moved against your will, and you have resistance to bludgeoning, piercing, and slashing damage.

You cannot cast spells and when you take the attack action you can only make unarmed strikes. Your unarmed strikes deal 2d8 bludgeoning damage.

Immediately after this ability ends you must make a DC 16 Constitution saving throw. If you fail, you gain one level of exhaustion. Once you use this ability it can't be used again until you finish a long rest.

Borne in the crust of the world; forged by rock and metal and time. Just as the bedrock from which it emerged, this armor bears no signs of damage save for the eons of erosion and weather that have taken their toll upon its surface. To don this hefty chassis is to bequeath your body to the earth itself, to become a force of nature; immovable, unbreakable, impossible. Listen now, the mountains shudder and the sand whispers of the coming force.
