Windrose Stargazer Tower Quest Guide: 19 Tumbaga Ingots and Observatory Puzzles

Updated: 2026-08-114 sections
Last updated:

The Stargazer Tower is one of the most substantial questlines in Windrose, offering a multi-stage dungeon experience that combines puzzle-solving, combat, and exploration. The quest, titled Fate of the Prophets, takes you through an ancient observatory tower built by a lost civilization, culminating in a challenging boss encounter and rewarding some of the best endgame equipment in the game.

Prerequisites: To begin the Stargazer Tower quest, you must have completed the main story questline up to Chapter 7, reached at least level 35, and unlocked the Astral Key item through the Sage of Tides side quest. The Astral Key is required to open the tower's sealed entrance. If you have not yet obtained the Astral Key, speak to the Sage of Tides NPC at any major port after completing Chapter 7 to begin the side quest.

Recommended preparation: The tower is a substantial dungeon that takes approximately 2-3 hours to complete on your first attempt. Bring a well-upgraded ship with at least a Tier 2 hull and 24lb cannons, as you will need to fight through a naval blockade before reaching the tower. Your crew should be at least level 30 with full health and morale. Stockpile healing potions (at least 15), repair materials (at least 50 wood and 20 cloth), and cannonballs (at least 100 of each type you use).

Rewards overview: Completing the Stargazer Tower quest rewards you with the Astral Compass (a navigation upgrade that reveals hidden areas on your map), the Starforged Blade (one of the best swords in the game), 19 Tumbaga Ingots (used for endgame crafting), and the Fate of the Prophets achievement. The tower also contains numerous treasure chests with gold and equipment that can be looted along the way.

Stargazer Tower Location and Entry

The Stargazer Tower is located on a remote island in the far northeastern corner of the Windrose map. The island is not marked on your map until you approach it, so you will need to sail to the coordinates revealed by the Sage of Tides during the prerequisite quest.

Reaching the island: Sail northeast from the nearest major port. The journey takes approximately 30 minutes of real-time sailing. Along the way, you will encounter a naval blockade of ghost ships that guard the approach to the tower island. These ghost ships use spectral cannons that deal spiritual damage (not reduced by standard armor), so bring spiritual resistance gear if available. Defeat or evade the blockade -- there are approximately 5-7 ghost ships, and they respawn after 30 minutes if you need to leave and return.

Entering the tower: Once you reach the island, dock at the small harbor on the southern shore. The tower entrance is at the top of a hill, accessible via a winding path. At the entrance, you will find a sealed door with an astral lock. Use the Astral Key from your inventory to open the door. A cutscene plays showing the tower's history, after which you gain access to the interior.

The tower interior is divided into five floors, each with a different theme and challenge. Floors 1-3 contain the observatory puzzles, Floor 4 contains the Tumbaga Ingot vault, and Floor 5 contains the final boss arena. Each floor must be completed in order to unlock the stairs to the next.

All Three Observatory Puzzles and Solutions

The Stargazer Tower features three observatory puzzles, one on each of the first three floors. Each puzzle is thematically tied to astronomy and requires you to interact with telescope mechanisms, constellation murals, and astral projection devices. This section provides solutions for all three puzzles.

Puzzle 1: The Constellation Alignment (Floor 1). This room contains a large telescope in the center and a mural on the wall showing a constellation pattern. To solve the puzzle, interact with the telescope and rotate it to match the constellation shown on the mural with the actual stars visible through the telescope lens. The telescope has three rotation controls: horizontal angle, vertical angle, and magnification. Match all three to the mural's constellation. The correct alignment is: horizontal 45 degrees right, vertical 30 degrees up, magnification level 3. When aligned correctly, the telescope emits a beam of light that unlocks the door to Floor 2.

Puzzle 2: The Planetary Orbits (Floor 2). This room contains a mechanical orrery -- a model of the solar system with planets on rotating arms. The puzzle requires you to arrange the planets in a specific configuration. On the wall, there are three murals showing planetary alignments at different times. You must replicate the alignment shown in the second mural (the one in the center). Interact with each planet's arm to set its position. The correct configuration is: innermost planet at 12 o'clock, second planet at 4 o'clock, third planet at 8 o'clock, outermost planet at 6 o'clock.

Tumbaga Ingot Locations and Final Boss

Floor 4 of the Stargazer Tower is the Tumbaga Ingot vault, where all 19 Tumbaga Ingots are hidden. This floor is a large maze-like area with multiple rooms and hidden passages. This section provides a comprehensive guide to finding all 19 ingots and defeating the final boss.

Tumbaga Ingot locations: The 19 ingots are distributed across the floor as follows: 5 ingots are in plain sight on pedestals in the main corridor. 4 ingots are in side rooms behind locked doors that require solving minor switch puzzles. 3 ingots are hidden behind breakable walls -- look for cracks in the wall and attack them with your melee weapon. 4 ingots are in underwater sections accessible through flooded passages. 2 ingots are rewards for defeating mini-boss enemies scattered through the maze. 1 ingot is hidden behind a false wall in the northwest corner of the maze -- walk into the wall to discover the secret passage.

Final boss: The Astral Prophet. Floor 5 is a circular arena where you face the Astral Prophet, the spirit of the tower's last inhabitant. The boss has three phases. Phase 1 (100-66% health): The Prophet uses spectral sword attacks and summons astral clones that mimic his attacks. Focus on dodging and dealing damage during recovery windows. Phase 2 (66-33% health): The Prophet creates a gravity field that pulls you toward the center of the arena. Stay near the edges and use ranged attacks. Phase 3 (33-0% health): The Prophet enrages, gaining increased attack speed and summoning meteor strikes. Dodge the meteors (marked by red circles on the ground) and focus on aggressive damage to end the fight quickly.

Frequently Asked Questions

Recommended level 35+ with a well-upgraded ship and crew of at least 6 members. The tower's enemies scale to your level, but being below 35 makes the combat encounters significantly harder and increases the risk of running out of healing items before the final boss.

Align the telescope to match the constellation shown on the wall mural, rotating it to match the star pattern in the sky. The correct alignment is horizontal 45 degrees right, vertical 30 degrees up, and magnification level 3, which projects a beam of light that unlocks the next floor.

Tumbaga Ingots are used to craft endgame equipment and weapons, making them one of the most valuable crafting materials in the game. They are required for crafting the Starforged Blade upgrade tier, the Astral Armor set, and several unique ship components that provide stat bonuses.

No, the tower is a one-time story quest, but you can return to the area to collect any missed items after completion. If you missed any Tumbaga Ingots, the ones in the vault area will still be there when you return, though the boss will not respawn.
