Find the Blood of Lathander

Key takeaways

Keep the following points in mind before entering the hidden chamber.

• Find the plaque and statue The investigation begins near a plaque beside a statue in Rosymorn Monastery. Examine environmental clues rather than treating the quest as a straightforward combat objective.
• Solve the stained-glass puzzle The stained-glass window puzzle is the safe route to the Dawnmaster’s Crest. Do not treat the crest as optional if you want to avoid the monastery’s destructive trap.
• Expect flexible exploration Combat is not the only way through the monastery and crèche area. The party can bypass some encounters and concentrate on reaching the relic.
• Reserve the crest for the final mechanism The correct crest is used during the mace retrieval sequence. Its purpose is to prevent the trap from escalating when the relic is taken.
• The reward is more than a melee weapon The Blood of Lathander combines holy light, an emergency healing effect, and access to Sunbeam. Those features make it particularly attractive for encounters involving undead.

Find the Blood of Lathander: overview

Find the Blood of Lathander is an optional relic quest at Rosymorn Monastery in Baldur's Gate 3. Its central challenge is retrieving a legendary mace from a hidden chamber while avoiding a trap that can destroy the nearby Githyanki Crèche.

The quest begins when the party investigates a plaque near a statue inside Rosymorn Monastery. That clue points toward the monastery’s history and eventually leads to a stained-glass window puzzle. Solving the puzzle is not simply a lore exercise: it provides the Dawnmaster’s Crest, the item that makes the later retrieval of the mace safe. The monastery and the nearby crèche can be explored through combat, stealth, or other forms of traversal, so the party does not have to defeat every encounter before pursuing the relic.

The Blood of Lathander is a legendary +3 mace hidden in a secret chamber beneath the monastery. Its permanent holy light is especially useful against fiends and undead, because nearby enemies of those types can be blinded if they fail a Constitution saving throw. The weapon also carries Lathander’s Blessing, which can restore the wielder and nearby allies when the wielder falls to zero hit points, and it grants the ability to cast Sunbeam once per long rest.

The crucial decision comes at the end of the search. Placing the correct Dawnmaster’s Crest during the retrieval sequence allows the party to claim the mace without activating the monastery’s destructive trap. Attempting the retrieval without the crest can trigger a response capable of destroying the nearby Githyanki Crèche, turning a successful equipment hunt into a major environmental and story consequence. Save before the final interaction if the party has not yet confirmed that it possesses the correct crest.

The quest is valuable even for a party that does not plan to use a mace as a primary weapon. Its light, emergency healing effect, and Sunbeam access give it strong utility in encounters involving undead, while the route through Rosymorn Monastery also rewards careful observation. A character such as Shadowheart is a natural candidate for the weapon because of its cleric-oriented utility, but the final choice depends on the party’s equipment and combat roles.

WalkthroughSpoilers

1. 01

   Begin the relic investigation

   Enter Rosymorn Monastery and look for the statue clue

   Explore Rosymorn Monastery until you find the statue and its nearby plaque. Interact with the plaque rather than simply moving onward, because this environmental clue establishes the direction of the relic investigation and can be easy to overlook among the monastery’s other points of interest.

   Location: Rosymorn Monastery

   TipUse a manual save before exploring the deeper monastery if you want a safe return point.

2. 02

   Find the puzzle that reveals the crest

   Inspect the stained-glass window

   Continue to the room containing the stained-glass window puzzle and examine the surrounding fixtures. The puzzle is built around the monastery’s ceremonial weapons and the imagery in the window, so inspect the room carefully instead of trying to force the final chamber immediately.

   Location: Rosymorn Monastery

   Watch outDo not assume that reaching the hidden chamber first makes the Dawnmaster’s Crest unnecessary.

3. 03

   Solve the stained-glass window puzzle

   Complete the ceremonial weapon arrangement

   Place the relevant ceremonial weapons on the matching parts of the stained-glass display. The arrangement is based on the clues shown by the window and the monastery’s dawnmasters; if a weapon is missing, search the surrounding monastery rather than abandoning the puzzle.

   Location: Stained-glass window room

   TipKeep the party’s inventory organized so ceremonial weapons are easy to identify when the display is inspected.

4. 04

   Obtain the Dawnmaster’s Crest

   Take the Dawnmaster’s Crest

   After the stained-glass puzzle is solved, collect the Dawnmaster’s Crest that the mechanism makes available. Confirm that it is in the active party’s inventory before descending farther, because the crest is the safeguard for the relic retrieval.

   Location: Stained-glass window room

   Watch outLeaving the crest behind can turn the final interaction into a destructive trap.

   Missable
5. 05

   Reach the hidden relic chamber

   Navigate toward the secret chamber

   Follow the monastery’s lower route toward the hidden chamber containing The Blood of Lathander. The route can include hostile encounters, but the party may bypass some of them through positioning and exploration rather than fighting every creature in the area.

   Location: Lower Rosymorn Monastery

   TipA party that wants the mace quickly should focus on the route and avoid unnecessary fights once the crest is secured.

6. 06

   Set up the safe retrieval

   Prepare before touching the relic

   Make a manual save at the entrance to the final chamber and check that the Dawnmaster’s Crest is still available. Review the party’s escape plan before interacting with the mace, since the wrong retrieval choice can endanger the nearby Githyanki Crèche.

   Location: Secret chamber beneath Rosymorn Monastery

   Watch outThe destructive consequence is tied to the final retrieval, not merely to entering the chamber.

7. 07

   Disable the relic’s destructive safeguard

   Insert the Dawnmaster’s Crest during retrieval

   Use the Dawnmaster’s Crest in the designated mechanism when the chamber presents the opportunity to claim the mace. This is the important safety step: the crest allows the party to take the relic without triggering the catastrophic trap.

   Location: Secret chamber beneath Rosymorn Monastery

   Missable
8. 08

   Recover the quest reward

   Claim The Blood of Lathander

   Take The Blood of Lathander after the crest has been accepted. The weapon is a legendary +3 mace with holy light, Lathander’s Blessing, and the ability to cast Sunbeam once per long rest.

   Location: Secret chamber beneath Rosymorn Monastery

   Checkpoint
9. 09

   Complete the quest without losing the nearby crèche

   Leave the monastery safely

   Once the mace is secured, withdraw from the chamber and continue the party’s exploration only after confirming that the trap did not activate. If the party attempted the retrieval without the correct crest, prioritize escaping the resulting danger over collecting additional loot.

   Location: Rosymorn Monastery and the nearby Githyanki Crèche

   Watch outFailing to use the correct crest can destroy the nearby Githyanki Crèche.

Mission mechanics

The quest combines environmental investigation with an item-gated retrieval sequence. The plaque near the statue points the party toward the monastery’s history, while the stained-glass window puzzle turns that history into a practical objective. The Dawnmaster’s Crest is therefore both a puzzle reward and a safety key; obtaining it before touching the mace is the central mechanical lesson of the quest.

The monastery’s layout supports more than one style of play. The party can fight through hostile areas, use stealth and positioning, or bypass selected encounters while moving toward the relic. This flexibility means that the quest does not require a single party composition, although characters who can inspect the environment carefully and manage a dangerous escape have an easier time.

The Blood of Lathander’s utility is concentrated in encounters with fiends and undead. Its continuously emitted holy light can blind nearby enemies of those types when they fail a Constitution saving throw, while Lathander’s Blessing provides a once-per-long-rest recovery effect when the wielder reaches zero hit points. Sunbeam adds a powerful once-per-long-rest offensive option to the weapon’s package.

The final chamber creates a risk-and-reward interaction rather than a normal treasure pickup. Taking the mace without the correct crest can trigger a trap capable of destroying the nearby Githyanki Crèche. The safest approach is to treat the crest as mandatory, save before the final interaction, and avoid experimenting with the mechanism on an unsaved attempt.
