Dragon Turtle Plate
Armor (plate), very rare (requires attunement)
You have a +1 bonus to AC and resistance to fire damage while wearing this armor fashioned from a dragon turtle hatchling's shell.
As an action, you can exhale scalding steam in a 60-foot cone. Each creature in that area must make a DC 16 Constitution saving throw, taking 9d8 fire damage on a failed save, or half as much damage on a successful one. Being underwater doesn't grant resistance against this damage. The armor can't be used this way again until you complete a long rest.
If you are knocked prone while wearing this armor, flip a coin. If you lose the flip, you fall on your back. To stand up, you must succeed on a DC 10 Dexterity check on your turn and then use all your movement for that turn. Another player may use their action to get you on your feet.
To become a merknight of the Order of the Trench, you must undergo a perilous mission. This quest takes you into the nest of a dragon turtle, where you must slay a hatchling and acquire its shell. This bony carapace will become your suit of armor, so finding an appropriately sized hatchling is very important if you want to look good.
