Balthazar Boss Tips

Gauntlet of Shar

Balthazar's Location

Balthazar can be first met in the Gauntlet of Shar. They would be located in the Far West of the location. From the cloaker room, head north and go down the stairs. You'll see a giant locked door. You can lockpick or attack it until it breaks down. Now head to the room located east and interact with the Altar to Shar (X:-807 Y:-816).

 Now go to the middle and pull the lever on the left side to open the door ahead. As you enter the room, you will find three undead skeletons. These are Balthazar's Undead Servants and they will start a conversation. From here on out, you will now have an opportunity to fight them and remove them from the board.

Balthazar's Gauntlet of Shar Tips

1. If Nere survives the events of the Grymforge, you will have to fight them as they would be with Balthazar at this point.
2. As pointed out, fighting Balthazar in this point would mean he would have a smaller entourage compared to their encounter in the Shadowfell.
3. Balthazar will be accompanied by Ghoul Medics, possibly Nere and Flesh, the flesh golem.
4. An interesting strategy is to acquire the Summon Golem Bell and get Flesh Killed before fighting Balthazar in the Guantlet of Shar. This will remove another enemy you have to deal with in this fight. Flesh is the most deadliest source of a problem beyond Balthazar themselves in this fight. Therefore, this removes a Tank and another unit from Balthazar's Retinue here in the Gauntlet of Shar. The most significant problem with Flesh is that they have a tremendous amounts of health and therefore would need a few more hits and thus become an annoyance if they do not defeat you.
5. Anti-Undead weapons or magic like Turn Undead will be useful here as Balthazar primarily utilizes the undead as their servants

Shadowfell

1. If you surprise him with a sneak attack and proceed to cast Counterspell as he's trying to summon his undead, you'll have a very easy kill.  It is also possible to push him off the edge and insta-kill him, but you won’t get any loot.
2. With some careful positioning, it's possible to end the fight with Balthazar very quickly, before he summons minions.  Before the final jump, Separate one member of your party.  In stealth, manoeuvre them onto the cliff to his left, so that you're almost in front of him but still out of his vision.  An Arrow of Roaring Thunder or similar can knock him out of the arena.
