Endgame secrets and targeted loot

Fixed Hackable Tower rewards

Each of the 106 Ancient Hackable Towers holds one fixed prize behind a lock. Beat the lock, then use the unlocked panel to claim it. These are the ones worth a detour. Every row opens the map at the tower, where its card shows the lock and the full reward.

Rewards, coordinates, locks and Pal fight bosses from the game files. Accessory prizes are the item itself or its schematic, as the tower card shows.

Hidden chests and side routes

Hidden marine-base chest west of Curved Redrock (player report, October 5): approach the outside next to the two large generators, take the stairs to the guarded side door, hop the orange barrier inside, and break the wall on your right at the end of the hallway.
Ocean Raider east of Feybreak Tower (player report, August 30): if you can see the chest but the doors seem to lead nowhere, look for a breakable wall. The way in can start outside, not on the deck above the chest. One player broke the wall with shots, another with a sword.
Sunreach Skies dungeon (player report, September 13): on the southeastern floating island, check in front of the teleport altar around (−93, −1499). Regular Eidrolon live inside, handy as a hauler or breeding stock.
Sunreach defense-tower chests that stay empty (player reports, July–August): several players found the tall wooden towers didn't refill, even after several in-game days. Nobody found a reliable reset; farm the dungeon, fishing or supply drops instead.
World Tree sealed chests and the 38 chests and 24 junk piles are in the World Tree farming guide.
A big Alpha with a pack but no boss icon (player report): look around for a nest with eggs, and catch the Alpha before you leave. One player lost a Direhowl when they walked away.

Optional bosses and shortcuts

Hartalis raid without hunting random fragments

Hartalis Slab Fragment Hartalis Slab

The Feybreak and Sunreach Hard expeditions each always bring back 1–2 Hartalis Slab Fragments. Four fragments make a Hartalis Slab at the Ancient Workbench. Offer it at a Summoning Altar for a Lv 70 Hartalis. Bring Dark attackers: Hartalis is Neutral. Use a separate raid base.

Fragments, recipe and level from the game files.

Terra Blade and Terraprisma schematics

Terra Blade Schematic Terraprisma Schematic Celestial Sigil

Pocketpair added two missions at Fisherman's Point in 1.0.4. Beyond Dimensions asks for the Eye of Cthulhu and pays a Terra Blade schematic. From the Far Side of the Moon is the Moon Lord: accept it before you make the Celestial Sigil (100 Hallowed Bars), then turn it in for a Terraprisma schematic.

The Calamity Door and the final boss

Players report: the door checks the World Tree guardians and eight Key Spheres from the faction towers, Zoe through Auri. If it says spheres are missing, check Key Items and clear the matching tower before hunting for a hidden pickup. The What's next? guide has every main mission in order.

Zenara Hat and Psycho Gravity

Zenara Hat Dark Skill Fruit: Psycho Gravity

Player tip: both come from Zenara & Astralym on Hard, a raid-style fight. When Astralym moves to the centre and starts charging, aim at its wings to interrupt it.

Crossover gear for Battle Tickets

V 1 Armor Schematic V 2 Armor Schematic

The Arena shop sells the V 1 and V 2 Armor schematics for 1,000 Battle Tickets each. Everything else you can buy or farm is in the Legendary schematics lookup.

Free work books from the Pal Critics

Community tip: show each Pal Critic the Pals they ask for, in order. The Transporting chain ends with Kingpaca Cryst at Cold Shore, Watering with Lyleen at the Sakurajima Mushroom Wetlands, and Handiwork with Bastigor at the Stone Pillar Cave Entrance. Each chain pays its matching Applied Handbook I.

Easter eggs and odd encounters

Zoe's Halloween Costume: the game has a schematic for it: "a memo of Zoe's mutterings. Craft it at a workbench and deliver the finished piece to her." Players find Zoe at the Desolate Church around (65, −412) after beating Zoe & Grizzbolt.
9 journals in the World Tree: turn on the journals layer and bring a flying mount; two pairs sit at different heights. Show the World Tree journals.
A treasure chest that runs away: Mimog sits still as a chest and bolts when hit. Block its escape before you start if you want to catch it.
The desert "Mario block" (player interpretation, July): players compared a cube-like desert encounter to a Mario block. The cube-shaped Alpha out there is Tetroise, Lv 55, at (436, 380), northeast of Duneshelter.
