What is the reward for defeating the optional boss in the Arcane Tower in Baldur's Gate 3?

Defeating the optional boss in the Arcane Tower in Baldur's Gate 3 is a challenging but rewarding endeavor. The Arcane Tower is located in the Underdark, a vast and dangerous underground area filled with unique enemies and hidden treasures. The optional boss in question is Bernard, a powerful construct that guards the tower. To face Bernard, you must first navigate the tower's puzzles and traps, which are designed to test your problem-solving skills and combat readiness.

The first step in reaching Bernard is to enter the Arcane Tower. The tower is accessible from the Underdark, and you can find it by exploring the area thoroughly. Once inside, you will encounter a series of puzzles and traps that must be solved or avoided. One of the key puzzles involves activating a series of magical generators that power the tower. These generators are scattered throughout the tower, and you must interact with them in the correct order to progress. Pay close attention to the environmental clues, such as glowing runes or inscriptions, as they often provide hints about the correct sequence.

As you ascend the tower, you will encounter various enemies, including animated armors and arcane turrets. These enemies can be tough to deal with, especially if you are not prepared. It is important to have a balanced party composition that includes both melee and ranged fighters, as well as a healer or support character. Spells like Fireball, Magic Missile, and Healing Word can be particularly useful in these encounters. Additionally, make sure to use the environment to your advantage. For example, you can lure enemies into narrow corridors where they can be easily targeted by area-of-effect spells.

Once you reach the top of the tower, you will encounter Bernard. Bernard is a powerful construct with high health and strong attacks. He is immune to many status effects, so you will need to rely on raw damage output to defeat him. Before engaging in combat, make sure to buff your party with spells like Bless, Haste, and Shield of Faith. These spells can significantly increase your chances of success. During the fight, focus on dealing as much damage as possible while keeping your party alive. Use crowd control spells like Hold Person or Sleep to temporarily disable Bernard and give your party a chance to regroup.

One common mistake players make is underestimating Bernard's strength. He hits hard and can quickly overwhelm an unprepared party. Make sure to have plenty of healing potions and scrolls on hand, and don't be afraid to use them liberally. Another mistake is not utilizing the environment to your advantage. The top of the tower has several chandeliers that can be shot down to deal area damage. Use these to your advantage to deal extra damage to Bernard.

Advanced techniques for this fight include using stealth to get the first strike. If you have a rogue or ranger in your party, you can use their stealth abilities to get into a favorable position before the fight begins. This can give you a significant advantage, as you can deal a lot of damage before Bernard has a chance to react. Additionally, consider using summons to distract Bernard. Spells like Conjure Animals or Animate Dead can create additional targets for Bernard to attack, giving your party more time to deal damage.

In terms of D&D rules and mechanics, Bernard is a construct, which means he is immune to many status effects like poison, disease, and charm. However, he is vulnerable to physical damage, so focus on using weapons and spells that deal direct damage. Spells like Magic Missile and Eldritch Blast are particularly effective, as they cannot miss and deal consistent damage.

The reward for defeating Bernard is the Sussur Greatsword, a powerful weapon that deals additional force damage and has a chance to silence enemies on hit. This weapon is particularly useful for melee fighters and can be a game-changer in tough battles. Additionally, you will gain access to the rest of the tower's treasures, including rare crafting materials and powerful magical items.

In conclusion, defeating the optional boss in the Arcane Tower is a challenging but rewarding experience. By carefully navigating the tower's puzzles and traps, preparing your party for combat, and utilizing advanced techniques, you can overcome Bernard and claim the powerful Sussur Greatsword. Remember to use the environment to your advantage, and don't underestimate the importance of buffs and healing. With the right strategy and preparation, you can emerge victorious and reap the rewards of your efforts.
