Ever since Mathem's A New Reign update log has been removed, @Hobgoblino and myself have thought about opening a thread containing everything added in the A New Reign DLC in its current up to date state.
Crafted Items & Structures

Moondial - Prestihatitator tier, 1 Blue Moonlens, 2 Moonrocks and 2 Ice - Reflects the moon phase on the water surface at any time of the day. If empty it means it’s a new moon. Will always be empty in caves. Emits light based on the moon phase: No light for new moon, waxing crescent or waning crescent, a bit of light for first or third quarter, decent light for waxing gibbous or waning gibbous and a lot of (pointless) light for full moon.
Feather Pencil - Science Machine tier, 1 Twig, 1 Charcoal and 1 Jet Feather - Used to craft a Map Scroll or to draw on a Mini Sign.
Mini Signs - Science Machine tier, 1 Board gives 4 Mini Signs - Dropping an item near it and drawing on it with a Feather Pencil puts the item's icon on the sign. Can be dug up with a Shovel.
Cartographer's Desk - Science Machine tier, 1 Compass and 4 Boards - Makes you able to craft a Map Scroll when near it.
Map Scrolls - Cartographer’s Desk tier, 1 Feather Pencil and 1 Papyrus - Changes if you're in the Caves or in the Overworld. When crafted contains the map that the player crafting it has revealed. Reading it discovers said parts of the map for whoever reads it.
Potter's Wheel - Science Machine tier, 2 Cut Stones, 2 Boards and 4 Twigs - Allows access to the Sculpture tab. Can craft 8 different Figures. 2 of them are already unlocked, 6 of them require the respective sketch from Marble Sculptures. The color of the Figure is based on the material placed on the Potter’s Wheel, black for Cut Stone and white for Marble.
Figures - Potter’s Wheel tier, 2 Rocks and 1 Cut Stone/1 Marble - They can only be carried on the chest slot with an empty hand slot. When carried the player will be slowed significantly, but this effect is negated if the player is riding a Beefalo. Can be hammered to obtain the Cut Stone or Marble used. If a Knight, Bishop or Rook figure is hammered during the night of a new moon, it will spawn the respective level 1 Shadow Piece.

Muslight - Rare Blueprint tier (Toadstool), 1 Shroom Skin and 1 Bucket-o-Poop - Has 4 slots. Emits light when Light Bulbs, Lesser Glowberries or Glowberries are placed inside of it. The light radius is bigger the more items it contains, up to 4. Makes items inside of it last twice as long.

Marble Sculptures - Spawns randomly on the Surface - Mining the pawn or muse Marble Sculpture will destroy the statue, dropping some Marble and the respective Sketch.

After repairing it, it can be mined and destroyed only during the night of a full moon or a new moon. If mined during a full moon, the respective Clockwork will spawn but if mined during a new moon the respective level 1 Shadow Piece will spawn instead. The Marble Sculpture will drop the respective Sketch in both cases.
Moon Stone - Spawns on a Grass Turf patch in a Forest Biome - Can be repaired with Moon Rocks or Cratered Moonrock. If fully repaired, any staff can be put in the Moon Stone, but most will have no effect. If a Moon Caller’s Staff is placed, a Polar Star will appear on the Moon Stone as long as the staff is inside. If a Star Caller’s Staff is placed during the night of a full moon, the Moon Stone will start to charge, attempting to revive any Suspicious Moonrock around it and spawning Werepigs and Hounds (if there’s less than 6 Werepigs or Hounds around it). Any Werepig or Hound around the Moon Stone will try to attack it. After being attacked too many times, the Moon Stone will break, dropping the staff and some Moon Rocks. If the Moon Stone is protected for long enough, the Star Caller’s Staff will turn into a Moon Caller’s Staff. Werepigs and Hounds around the Moon Stone will turn into a Suspicious Moonrock whenever the event ends, which can be if the event is successful, the Moon Stone is destroyed, the Star Caller’s Staff is manually removed from the Moon Stone or the night ends.
Hole/Toadstool - 3 Holes will spawn randomly in the Caves - Out of the 3 Holes, only one will contain a Toadstool. When a Toadstool is chopped 3 times, Toadstool (the giant) will spawn.

If the fight succeeds, a new Toadstool will spawn in a random Hole after 20 days.

Shadow pieces attack nearby players and break any Knight, Bishop or Rook Figure, spawning the respective shadow from it. When a different shadow type of the same level which hasn’t been used already to level up dies close to a shadow, that shadow will level up. This means you need all 3 types to obtain a level 3 shadow. Shadow Pieces increase their stats every time they level up. Level 2 and 3 shadows’ attacks will scare any friendly Pigs or Bunnymen for a few seconds. Knights do a single target attack and attempt to kite. Bishops can become invulnerable, turning into bats and dealing quick, constant damage around them. Rooks chase the player and then teleport on top of them, dealing AoE damage.

Doesn’t have a direct attack. He will instead throw a few Boomshrooms around him once in a while. These Boomshrooms will explode after a short delay, dealing 100 damage. Occasionally, he will poison 1 or 2 players around him. Poisoned players will drop a spore cloud under theirselves after a short delay. Spore clouds deal 20 damage every second and quickly spoil food items. Every once in a while Toadstool will stop attacking and instead will gain an insanity aura and spawn Sporecaps. Based on the amount of Sporecaps around him, Toadstool will have up to 80% damage protection, faster movement speed, up to 250 damage Boomshrooms, more Boomshrooms and more frequent Boomshroom attacks. Sporecaps can be chopped after 10 axe hits or lit on fire. If burnt, they will drop a spore cloud. Every time Toadstool loses ⅓ of his total HP, he will drop 1 Shroom Skin and scream, scaring any friendly Pigs or Bunnymen for a few seconds. After he’s under ⅓ HP, he will sometimes slam the ground twice, dealing 50 damage 4 times and causing a short earthquake.
