Blood of Lathander
📋 Overview
The Blood of Lathander stands as one of the most powerful and sought-after weapons in all of Baldur's Gate 3, a LEGENDARY mace hidden deep within the crumbling halls of Rosymorn Monastery in the Mountain Pass region of Act 1. Named after Lathander, the Morninglord — the god of dawn, spring, and renewal — this sacred weapon embodies the divine light that pushes back against the shadows threatening the Sword Coast.
This legendary mace deals 1d8 + 2 bludgeoning damage on a successful hit, but its true power lies in its extraordinary magical properties. The Blood of Lathander grants its wielder access to the Sunbeam spell, a devastating 6th-level evocation spell that projects a brilliant beam of light dealing 6d8 radiant damage to all creatures in its path. Even more remarkably, the mace possesses a once-per-long-rest resurrection ability that can bring a fallen companion back from death with 50% of their hit points — a game-changing feature that can turn the tide of the most desperate battles.
Beyond its combat applications, the Blood of Lathander carries immense narrative weight. The weapon represents the eternal struggle between light and darkness that defines the Baldur's Gate 3 storyline. Its acquisition requires players to solve one of the most intricate environmental puzzles in the game, navigate the politically complex Crèche Y'llek occupied by githyanki warriors, and ultimately prove themselves worthy of wielding a god's blessing.
What makes this weapon truly exceptional for Act 1 is how dramatically it shifts your party's power curve. Acquiring the Blood of Lathander before venturing into the Shadow-Cursed Lands of Act 2 gives your party a massive advantage. The Sunbeam spell alone can decimate groups of shadow creatures vulnerable to radiant damage, while the resurrection ability provides invaluable insurance during difficult encounters. Many veteran players consider this acquisition to be the single most impactful power spike available in the first act of the game.
The weapon's lore connects deeply to the githyanki storyline involving Lae'zel and the search for the Mysterious Artefact (the Astral Prism). The githyanki have occupied Rosymorn Monastery and established Crèche Y'llek in its depths, creating a tense military atmosphere where every conversation can turn hostile. Navigating this environment requires careful diplomacy, strategic thinking, and thorough exploration to uncover the hidden chamber where the Blood of Lathander has rested for centuries.

⚔ Acquisition Method
Obtaining the Blood of Lathander requires completing a multi-step quest chain that combines environmental puzzle-solving, stealth or combat encounters, and precise timing. The acquisition can be broadly divided into three major phases: Reaching Rosymorn Monastery, Solving the Stained-Glass Window Puzzle, and Navigating the Ceremonial Chamber Traps. Each phase presents unique challenges that test different aspects of your party's capabilities.
Phase 1: Reaching Rosymorn Monastery
The journey begins at the Mountain Pass, accessible after leaving the Emerald Grove or Blighted Village areas. From the Mountain Pass waypoint, head northeast along the mountain trail. You will encounter a bridge guarded by Eldra Luthrinn and a group of Flaming Fist mercenaries who are investigating strange githyanki activity in the region. You can bypass them through dialogue (Deception or Persuasion checks), or simply sneak past if you prefer to avoid conversation.
Continue across the bridge and follow the path upward. The monastery becomes visible as a massive stone structure perched on the mountainside, its ancient walls weathered by centuries of wind and snow. Upon entering the monastery grounds, you will encounter several hostile Eagles nesting in the courtyard — these are no ordinary birds but surprisingly tough opponents. Clear them or sneak past to gain access to the main building.
Phase 2: The Stained-Glass Window Puzzle
Inside the monastery, make your way to the main chamber with the massive stained-glass window depicting Lathander's symbol — a golden sunrise over mountains. This room contains the first major puzzle. You will notice four pedestals arranged around the chamber, each designed to hold a ceremonial weapon. The puzzle requires placing the correct weapons on the correct pedestals based on clues hidden in the environment.
The solution comes from examining the stained-glass window itself and the mural paintings on the walls nearby. Each section of the window depicts a different Dawn Master — ancient monks who once tended this sacred site — along with their associated weapon. The correct placement is:
When all four weapons are correctly placed, a hidden mechanism activates, granting you the Dawnmaster's Crest — a key item that will prove essential for safely claiming the Blood of Lathander later. If you attempt to take the mace without this crest, you will face a catastrophic trap that can easily wipe your entire party.
Phase 3: Crèche Y'llek and the Ceremonial Chamber
With the Dawnmaster's Crest in hand, proceed to the lower levels of the monastery where Crèche Y'llek is located. The githyanki have established a military outpost here, and their leader Kith'rak Therezzyn maintains strict order. You can either fight your way through the crèche or use diplomacy to gain access — if Lae'zel is in your party, special dialogue options become available that can significantly ease navigation.
The Blood of Lathander is housed in a secret chamber accessed through the Inquisitor's Chamber. You must speak with Inquisitor Viconia or find the hidden entrance to the ceremonial chamber. The room itself is protected by multiple layers of magical defenses:
Here is where the Dawnmaster's Crest becomes crucial. Interact with the weapon's housing mechanism and insert the crest to safely deactivate the barriers. Without it, you have approximately 4 rounds to escape the chamber before the failsafe detonates, destroying the weapon and likely killing your entire party. With the crest, the weapon descends safely into your hands, and you can leave without incident.
Alternative: The Theft Route
It is technically possible to acquire the Blood of Lathander without solving the stained-glass puzzle, but this route is extremely dangerous and generally not recommended for first-time players. If you have a character with exceptional thievery skills (Sleight of Hand proficiency, high Dexterity, and bonuses from items like the Gloves of Thievery), you can attempt to steal the mace directly from its housing. This triggers the failsafe trap immediately, giving you only 4 rounds to escape the blast radius.
To survive this approach, you must:
⚠ Critical Warning
The theft route is HIGHLY RISKY. If any party member is caught in the blast, they will take approximately 100 fire damage — instant death for most Act 1 characters. Always save before attempting this method. The puzzle route using the Dawnmaster's Crest is the intended and significantly safer acquisition method.
📋 Requirements
Before embarking on the quest for the Blood of Lathander, ensure your party meets the following prerequisites. Failure to prepare adequately can result in missed opportunities, dead companions, or the permanent loss of the weapon itself.

Skill Requirements for Key Checks
Several important skill checks appear during the Blood of Lathander quest chain. While none are strictly required (there are usually alternative paths), having these skills available significantly smooths the process:
Quest Prerequisites
The Blood of Lathander quest technically becomes available as soon as you reach the Mountain Pass, but certain story beats affect how you interact with the location:
Item Checklist
Bring these items to ensure a smooth run through the monastery:
🗺 Step-by-Step Route
Follow this comprehensive step-by-step guide to acquire the Blood of Lathander from start to finish. Each step includes precise location details, map coordinates, NPC interactions, and the exact dialogue choices required for the optimal path.
Step 1: Travel to the Mountain Pass (Act 1)
From your camp or any waypoint, fast travel to the Mountain Pass waypoint at coordinates X: -154, Y: 30. This area becomes accessible after completing or bypassing the Emerald Grove conflict. As you approach the bridge leading to Rosymorn Monastery, you will encounter Eldra Luthrinn (Flaming Fist Scout) and her patrol.
Dialogue Options with Eldra:
Pro Tip: Passing the Persuasion check with Eldra marks the monastery location on your map and gives you a hint about the githyanki leader, Kith'rak Therezzyn. This information is valuable for the later diplomatic route through the crèche.
Step 2: Cross the Bridge and Ascend
Proceed across the stone bridge at X: -138, Y: 42. Be prepared for a potential encounter with githyanki patrols in this area — if you have not yet encountered githyanki in your playthrough, a squad of warriors may ambush you here. Defeat them or use stealth to bypass.
Follow the winding mountain path upward. You will pass several stone markers and weathered statues of Lathander. At X: -120, Y: 58, the path opens into the Rosymorn Monastery Courtyard. Save your game here — the eagle encounter is upcoming.
Step 3: Clear the Courtyard Eagles
The monastery courtyard is occupied by a nest of Giant Eagles (CR 3 beasts, approximately 45 HP each). There are typically 3-4 eagles in the initial encounter, with possible reinforcements arriving if the fight extends too long.
Eagle Encounter Strategy:
After defeating the eagles, thoroughly search the courtyard. A locked chest hidden behind a crumbling wall at X: -112, Y: 65 contains the Battleaxe of the Dawn Master — one of the four puzzle weapons. Use Thieves' Tools (DC 15) to open it.
Step 4: Enter the Main Monastery Hall
The main entrance to the monastery is at X: -118, Y: 62. Push open the heavy oak doors (or pick the lock DC 18 if you want to maintain stealth). Inside, you enter the Great Hall, a massive chamber with vaulted ceilings and the iconic stained-glass window at the far end.
Immediately upon entering, have your highest Perception character scout the area. There are several important interactable objects:
Step 5: Solve the Stained-Glass Window Puzzle
Examine the stained-glass window at the northern end of the Great Hall. The window depicts four panels, each showing a Dawn Master with their weapon. Reading the Ancient Scripture on the lectern provides additional context. The puzzle requires placing the correct ceremonial weapon on each of the four pedestals arranged in a semicircle before the window.
Weapon Locations:
| Dawn Master | Weapon | Location | How to Obtain |
|---|---|---|---|
| Vaseid | Mace | Main pedestal in Great Hall | Already in place, interact to take |
| Seed | War Pick | Upper floor, broken room | Climb via broken staircase or use Jump/Misty Step |
| Stockhold | Morningstar | Eastern wing storage room | Disarm traps (DC 16), pick lock on weapon rack (DC 18) |
| Welkinglory | Battleaxe | Courtyard chest | Thieves' Tools DC 15, obtained in Step 3 |
Puzzle Solution Order: The pedestals are labeled with engravings matching each Dawn Master. Place the weapons in this exact order:
- Take the Ceremonial Mace from the center pedestal — this temporarily deactivates the magical barrier protecting the eastern wing
- Travel to the eastern wing (watch for trap tiles) and retrieve the Morningstar from the trapped weapon rack
- Use the hidden lever behind the collapsed pillar (or Jump/Misty Step) to reach the upper floor and collect the War Pick
- If you have not already, retrieve the Battleaxe from the courtyard chest
- Return to the Great Hall and place each weapon on its matching pedestal
When all four weapons are correctly placed, a resonant chime echoes through the hall. The Dawnmaster's Crest materializes in a hidden compartment at the base of the central altar. This golden medallion is the key to safely claiming the Blood of Lathander.
Step 6: Navigate to Crèche Y'llek
With the Dawnmaster's Crest secured, proceed to the lower levels of the monastery. The entrance to Crèche Y'llek is through a heavy iron door in the western wing of the monastery, at X: -125, Y: 55.
If Lae'zel is in your party, she will initiate a conversation when you approach the door. Her presence opens unique dialogue options with the githyanki guards:
Diplomatic Route: If you successfully pass the dialogue checks, the githyanki allow you to enter the crèche as "honored guests." You can freely explore most areas, though certain sections remain restricted. You can speak with Kith'rak Therezzyn in the command chamber for additional lore and potential side quests.
Combat Route: If you choose to fight, prepare for a challenging encounter. The githyanki warriors are highly mobile fighters with multiattack capabilities and resistance to psychic damage. Use crowd control spells and focus fire on the Githyanki Knight first, as their leadership aura buffs nearby allies.
Step 7: Enter the Inquisitor's Chamber
Make your way through the crèche to the Inquisitor's Chamber at the lowest level. If you are on the diplomatic route, you may need to pick a lock (DC 20) or find an alternative entrance through a ventilation shaft (Perception DC 18 to spot the entrance at X: -140, Y: 48).
Inside the Inquisitor's Chamber, you will find Inquisitor Viconia (or her subordinate if she has been dealt with elsewhere in the story). The chamber contains the entrance to the Ceremonial Room where the Blood of Lathander is sealed. Look for a glowing archway at the northern end of the room — this is the sealed entrance.
Step 8: Claim the Blood of Lathander
Enter the Ceremonial Chamber through the glowing archway. The Blood of Lathander floats in a column of brilliant golden light at the center of the room, suspended above an ornate pedestal. As you approach, a magical barrier crackles with radiant energy — approaching without the Dawnmaster's Crest triggers the failsafe sequence.
SAFE METHOD (With Dawnmaster's Crest):
DANGER METHOD (Without Crest — NOT RECOMMENDED):
Step 9: Escape and Celebrate
With the Blood of Lathander safely in your inventory, make your way back out of the crèche. If you took the diplomatic route, the githyanki may become hostile upon realizing their sacred chamber has been breached — be prepared for a running fight through the crèche corridors. If you already cleared the crèche, simply walk out.
Return to your camp and equip the Blood of Lathander on your chosen character. The weapon is most effective on:
⚠ Gotcha Tips
After guiding hundreds of players through the Blood of Lathander acquisition, we have identified the most common mistakes, hidden dangers, and easily missed details. Read this section carefully to avoid frustrating setbacks.
Gotcha #1: The Failsafe Timer Is REAL
Many players assume they can tank the failsafe explosion or out-heal the damage. You cannot. The final detonation deals an average of 110 damage of mixed fire and radiant types. At Act 1 levels (5-7), even your tankiest character with maximum HP and temporary hit points will be obliterated. Always get the Dawnmaster's Crest. Do not try to be clever about stealing the weapon without it.
Gotcha #2: You Can Permanently Lose the Weapon
If the failsafe detonates while the Blood of Lathander is still in its housing, the weapon is DESTROYED. It does not respawn, it does not drop as loot, and there is no way to recover it in that playthrough. This is one of the very few truly missable legendary items in Baldur's Gate 3. Always save before entering the Ceremonial Chamber.
Gotcha #3: The Eastern Wing Traps Reset
The trap tiles in the eastern wing leading to the Morningstar weapon rack reset after each long rest. If you leave the monastery to rest and return, you must disarm them again. Additionally, the trapped weapon rack itself has a secondary trap that triggers if you fail the Sleight of Hand check by 5 or more — this deals 3d6 piercing damage and alerts nearby enemies.
Gotcha #4: Githyanki Diplomacy Has Consequences
If you take the diplomatic route through Crèche Y'llek and later betray the githyanki by taking the Blood of Lathander, this can affect Lae'zel's approval and potentially lock you out of certain githyanki-related story paths. Conversely, if you massacre the crèche before claiming the weapon, you lose access to unique dialogue and potential allies later in the game. Consider your roleplay approach carefully.
Gotcha #5: The Puzzle Weapons Can Be Missed
Each of the four ceremonial weapons required for the puzzle can be permanently missed if you are not thorough:
Gotcha #6: Shadowheart's Reaction Matters
If Shadowheart is in your party when you claim the Blood of Lathander, she has unique dialogue about the Morninglord. Depending on whether she has embraced or rejected Shar at this point, her reaction varies significantly. If she is on her dark Shar path, she may voice disapproval about wielding a weapon of light — though this does not prevent equipping it. On her redemption path, she speaks reverently about Lathander and gains a small amount of inspiration.
Gotcha #7: The Crest Only Works Once
The Dawnmaster's Crest is consumed when used to deactivate the barriers protecting the Blood of Lathander. If you somehow lose it before reaching the Ceremonial Chamber (for example, by having it stolen by a githyanki pickpocket, which can happen in the crèche), you cannot craft a replacement. Keep the crest on your main character in a protected inventory slot.
⚠ Spoiler Warning: Act 3 Consequences
Carrying the Blood of Lathander into certain late-game encounters can trigger unique dialogue options, particularly when dealing with followers of Shar or undead enemies. The weapon's radiant nature makes it especially effective in the Shadow-Cursed Lands and against certain Act 3 bosses. However, there are no negative consequences for wielding it at any point — Lathander's blessing is unconditional.
