The Blade of Frontiers is the companion quest for Wyll in Baldur’s Gate III. You’ll receive this quest automatically after allowing the famous hero to join your party when encountering him at the Druids’ Grove, provided he survived the initial goblin attack at the front gates.
How to Recruit Wyll
You’ll most likely meet Wyll at the Emerald Grove during the goblin attack upon your initial arrival. He’s the one who jumped off the gate to enter the fray. The first thing you’ll need to do if you want to recruit Wyll is make sure he doesn’t die during the battle. When that’s done, you can find him in the hollow of the grove training some young tieflings. Alternatively, if you found Karlach first, Wyll will show up to end her. You can then convince him to stop and join you there too.
Speak with him to trigger another mind melding session. You can then probe him for info on a devil he’s tracking and ask if he wants to join you to find a cure for the mind flayer in your head.
Hunt Down Karlach
As Wyll mentioned previously, he is on a quest to hunt down and kill the devil Karlach. To find her, you’ll want to head west of Emerald Grove to The Risen Road. She’ll be standing on a rock across a fallen tree bridge along the river.
Speak to her while Wyll is in the party to start up a conversation. You’ll learn that Karlach was forced to serve against her will and just wants to go home. You’ll then have a choice to make. You can let Wyll kill her which leads to a fight against Karlach or you can convince him to stay his blade. Doing so will present you with the opportunity to recruit Karlach. Either way, speak with him afterward. (We chose to recruit Karlach).
Rest at Camp
Head back to camp and do a Full Rest. This will trigger an event where a devil will show up in the camp. She’ll introduce herself as Mizora, Wyll’s patron, and come to punish him for not killing Karlach. If you stand up for Karlach, you’ll get approval from almost everyone. Mizora will then leave the camp giving you time to speak with Wyll.
Rescue Zariel’s Asset from Moonrise Towers
Continue traveling with Wyll until Act II when you reach Last Light Inn. After speaking with Jaheira in the Inn, rest at your camp to be visited by Mizora. She will task Wyll with freeing a demon that has been trapped at Moonrise Towers. If you pass a perception check, you’ll pick up on her needing this mission to be a success. You can then use this opportunity to have her release Wyll from his pact. If you pass a skill check, she will amend the contract after the job has been completed. Speak with Wyll afterward in camp.
This objective cannot be completed until you reach the Defeat Ketheric Thorm main quest towards the end of Act II.
The Grand Duke
To receive this objective, you’ll need to travel to Waukeen’s Rest. You can find it on the northwestern part of the map west of the Risen Road.
Once there, speak with Gauntlet Dain and persuade her to tell you what happened. She’ll respond that the Grand Duke was taken and the place burned to the ground. (When I did this Wyll was not in my party). Travel back to the camp and speak with Wyll. Mention the duke and he will freak out then tell you that the Grand Duke is his father. You can ask him more about his background, but make sure to promise that you’ll look for him.
Once you reach the mountain pass, there will be some corpses on the ground north of the Trielta Crags fast travel point.
Interact with them to find a Missive from Moonrise stating that the duke is being delivered to Moonrise Towers. Wyll was not in my party when I found this note, so I had to speak with him at the camp about the note for some dialog. The objective does not update.
You can’t do the next part of this quest until you’re on the Defeat Ketheric Thorm Act II main quest towards the end of the act. During the quest, you’ll learn the Duke is being taken to Baldur’s Gate. After dealing with Thorm, you’ll be free to pursue him.
Attend Gortash’s Ordination Ceremony
Once you reach Wyrm’s Rock Fortress in Baldur’s Bate, head to the right side to find the doors leading to the Audience Hall. Mizora can be found there near the doors. Speak with her then attend the ceremony. Afterward. return to Mizora and speak with her once more. She’ll then travel to camp where you can speak with her thrice by resting. During this conversation, she will offer Wyll a deal. She will tell him where to find his father in return he serves her eternally or she breaks his pact but doesn’t tell him where to find his father.
For our playthrough, we are going to break the pact and still save Wyll’s dad.
