The Autumn Banquet set is one of Crimson Desert's most visually striking armor collections. With dark base tones, golden embroidery, and layered fabric, it leans more toward refined nobility than battlefield brutality. The full set consists of five pieces — Cloth Cloak, Leather Boots, Plate Helm, Leather Armor, and Leather Gloves — each locked inside a hidden Treasure Chest somewhere in or around Demeniss. None of them are quest rewards or shop purchases; you have to physically track down every chest in the open world.
Quick answer: Collect all five pieces from hidden Treasure Chests at the Church of West Demeniss (cloak), Crescent Lake waterfall (boots), ruins west of the Kingshield Mountains (helm), the Sanctum of Mortification (armor), and a cave near Breezeblown Knoll (gloves).

Autumn Banquet Cloth Cloak — Church of West Demeniss
Open your map and look for the small church icon just above the word "Demeniss." Travel to the Church of West Demeniss and climb up onto the roof. On the back side of the church tower, there is a wall section that functions as a secret door — interact with it to push it open. The Treasure Chest containing the Autumn Banquet Cloth Cloak sits inside the hidden room behind that door.

Autumn Banquet Leather Boots — Crescent Lake waterfall
Head to the far north of Demeniss and locate Crescent Lake. The lake has a waterfall along its edge, and the boots are hidden behind it. Walk up to the waterfall and use a melee attack to clear the path through the water. Once you pass through, the Treasure Chest is immediately visible on the other side.
The exact waterfall can be tricky to pinpoint because there are multiple waterfall caves in the area northeast of the Crescent Camp point of interest. If the first cave you check is empty, try the neighboring one.

Autumn Banquet Plate Helm — Ruins west of the Kingshield Mountains
Travel west of the Kingshield Mountains and look for a set of ruins enclosed by rocks on all four sides. You'll need to jump down into the sunken area. At the top of the ruin structure, vines block the way forward. Use a fire-based attack or torch to burn the vines, which exposes the chest behind them.

Autumn Banquet Leather Armor — Sanctum of Mortification
The Leather Armor is inside the Sanctum of Mortification in Demeniss. Once you enter the sanctum, move to the opposite side of the glowing blue lights. You'll find a locked gate with two small lamps flanking it. Light both lamps to unlock the gate, then open the Treasure Chest behind it.
This lamp-lighting mechanic is used throughout Crimson Desert to open sealed doors in sanctums and dungeons. If you encounter a locked gate elsewhere, check for unlit torches or lamps nearby — the same principle usually applies.

Autumn Banquet Leather Gloves — Cave near Breezeblown Knoll
The final piece is located in the extreme north of the map, near the edge of a river at Breezeblown Knoll. Make your way to the small wooden bridge in the area. Face east so you're looking toward the bridge, then check to the right for a small cave-like opening at the water's edge. Climb up into the cave entrance and follow the path inside until you reach the Treasure Chest containing the Leather Gloves.
The cave mouth is easy to walk past because it blends into the rocky riverbank. If you're standing on the bridge and don't see it, drop down to the water level and scan the rock face to the south side of the bridge.

Full set at a glance
| Piece | Location | How to access the chest |
|---|---|---|
| Cloth Cloak | Church of West Demeniss | Climb the roof, push the secret door on the tower's back wall |
| Leather Boots | Crescent Lake, northern Demeniss | Melee attack through the waterfall, chest is directly behind it |
| Plate Helm | Ruins west of Kingshield Mountains | Jump into the sunken ruins, burn the vines blocking the path |
| Leather Armor | Sanctum of Mortification, Demeniss | Light both lamps beside the locked gate |
| Leather Gloves | Breezeblown Knoll, far north | Find the cave opening near the wooden bridge, follow the path inside |
All five pieces are concentrated in the northern half of the map, mostly within or near Demeniss. Once you equip the complete Autumn Banquet set, you'll see the full aristocratic look in your armor menu — dark fabrics layered with ornate gold detailing across every slot. There's no specific order you need to collect them in, so plan a route that hits the closest chest to your current position first and work outward from there.
