How to Beat Thisobald Thorm in Baldur's Gate 3: A Comprehensive Guide

Baldur's Gate 3 is filled with challenging boss encounters that require more than just brute force to overcome. One such encounter is with Thisobald Thorm, a massive undead master brewer with a penchant for drinking and combat. In this guide, we'll walk you through the two methods of defeating Thisobald Thorm, the skills and spells you'll need, and the best way to approach this encounter.

Who is Thisobald Thorm?

Thisobald Thorm is one of Ketheric Thorm's many children and can be found in The Waning Moon, a tavern located in the far west of the Shadow-Cursed lands in Act 2 of BG3. You'll encounter him while on the Punish the Wicked side quest, where you'll need to retrieve a ledger from the tavern.

All Methods to Defeating Thisobald Thorm in Baldur's Gate 3

There are two ways to defeat Thisobald Thorm: by drinking him under the table or engaging in a physical altercation. Both methods require a specific set of skills and spellcasting.

Drink With Thisobald Thorm in BG3

The first method involves winning a series of Skill Checks when you sit down to share a drink with Thisobald. You'll need to roll for a Constitution save to avoid becoming drunk or attempt a Sleight of Hand check to trick Thisobald into thinking you're drinking. You'll also need to succeed in a DC16 Performance Check to continue the drinking game. If you fail, you may be able to save yourself with a DC18 Deception Check.

Monks and Rogues are well-suited for this encounter, with Astarion being an excellent choice due to his Sleight of Hand and Deception capabilities. If you succeed in the Skill Checks, you'll continue to the next round of drinks, with a total of three rounds requiring you to pass at least five skill checks.

The second method involves combat, but with a twist: Thisobald is immune to Slashing, Piercing, and Bludgeoning damage, as well as Thunder damage. You'll need to rely on Elemental spells, such as Fire, Water, Lightning, or Acid-based ones, to deal damage.

Warlocks, Sorcerers, and Wizards are ideal for this encounter, as they can effectively use Elemental spells. The goal is to hit Thisobald with multiple Magical based attacks, while avoiding his drinks, which can change the element of his attacks. Eventually, he'll gain the Blacked Out status effect, making him vulnerable to various types of damage.

Best Way to Beat Thisobald Thorm in Baldur's Gate 3

Between the two methods, the Skill Checks challenge is generally easier, especially if you have a character with a high Constitution score and access to Inspirations. However, this may not be the case for everyone, and the combat fight against Thisobald is doable, albeit more challenging.

To increase your chances of success, ensure that you have a well-rounded character with a combination of skills and abilities, and don't hesitate to use Inspirations to reroll failed Skill Checks. With the right approach and a bit of strategy, you'll be able to defeat Thisobald Thorm and claim your rewards.
