The developers of Baldur’s Gate 3 designed most questlines so that they may be completed in multiple ways. Thus, giving the players more freedom in how they approach situations. This guide represents one method that is confirmed to unlock this achievement.

Bring Lae’zel with you to the Rosymorn Monastery. When you reach the monastery, collect 3 ceremonial weapons (details below). Place/throw the weapons on the pedestals that match their owners (examine the stained glass floor for clues).
Here are the weapons in order from left to right as you enter the room.
- Dawnmaster Vaseid – Ceremonial Battleaxe – 2nd floor Guardian
- Dawnmaster Welkinglory – Ceremonial Longsword (already in position)
- Dawnmaster Seed – Ceremonial Warhammer – Rooftop Eagle Nest
- Dawnmaster Stockhold – Ceremonial Mace – 1st floor Kobolds
After placing the weapons, collect the Dawnmaster’s Crest from the revealed bag. Now, head down to the Creche in the basement. Once there, navigate the halls toward the northeast corner and talk to the commander. Either tell her about the artifact or pickpocket the key from her (use on the pedestal beside the energy door). Follow the pathway toward the inquisitor and agree to help him.
When you reach the astral plane, talk with the Dream Visitor and agree to help her. Then, share what you saw with Lae’zel so she doesn’t leave the party. Take the portal back to the inquisitor’s room and be prepared for a fight. Focus the inquisitor down immediately to simplify the battle. Next, walk into the alcove on the west side of the room and turn the statues with one facing the direction you came and the other facing the wall. Use someone with high strength to move them.
Secret Chamber
Take the newly opened pathway to the Secret Chamber. Once there, destroy the Energy Source crystals and disarm the Dawnbreakers to proceed. You will need to move off the primary pathway to reach the crystals. When you reach the main objective, place the Dawnmaster’s Crest in the Crest Panel, releasing the Blood of Lathander, and unlocking the achievement.
The Blood of Lathander may also be grabbed if you have a way to get outside the traps that spring. As soon as you grab the mace (if you didn’t use the Dawnmaster’s Crest) a force field will surround you. Using something like Dimension Door can help get out of the initial trap.
