Slagsteel Cuirass (Patreon)

Armor (breastplate), legendary (requires attunement)

A jagged breastplate formed from heated stone and metal with a molten layer flowing below. This armor has 6 charges and regains 1d4 + 2 charges after a long rest. Properties of this armor ignore resistance to fire damage.

While this armor has at least 1 charge, it appears in its Igneous form. If it drops to 0 charges, it transforms into its Molten form until it regains a charge.

Igneous. You gain a +3 bonus to your armor class. You have immunity to fire damage.

While wearing this armor in its igneous form you can cast one of the following spells (spell save DC 14) by expending the necessary number of charges: Fire Shield (3 charges; warm shield only), Heat Metal (2 charges), Ice Knife (1 charge; +5 to hit; deals fire damage instead of cold damage), Wall of Stone (4 charges).

Molten. You shed the hardened exterior of this armor, unveiling its fiery core. The bonus to AC decreases to +1 and you have resistance to fire damage instead of immunity. While wearing this armor, your body exudes an intense heat that burns any flammable objects within 5 feet of you that aren't being worn or carried. While in its molten form, you gain the following properties:

• Your speed is increased by 10 feet.
• Your melee attacks deal an additional 2d6 fire damage.
• Whenever a creature comes within 5 feet of you for the first time on a turn, it takes 1d6 fire damage.

Many forget the might of the land, alive and breathing and moving all the while. Though we live comfortably upon the crust, the immeasurable energy running through the veins of our world seethes with impatience; bubbling just below the surface, ever threatening to burst from its stony prison at the first opportunity. Once unleashed, it becomes a force unstoppable as it surges forth to consume all in its path.
