In the quest to rescue Baldur’s Gate 3 Thaniel, defending the portal is a crucial encounter that requires strategic planning and effective combat tactics. This phase of the quest occurs just north of the Last Light Inn and presents a challenge that tests your party’s strength and coordination.

Combat Strategies

  • AoE Spells: Utilize area-of-effect spells like Fireball, Ice Storm, and Turn Undead to target multiple enemies at once, weakening their ranks and controlling their movements.
  • Positioning: Smartly position your party members to cover different angles and chokepoints, making it difficult for enemies to approach the portal.
  • Crowd Control: Use spells or abilities that impose crowd control effects such as stunning, freezing, or immobilizing enemies to buy time and prevent them from reaching the portal.

Enemy Types

Enemy Types
  • Shadows & Wraiths: The initial waves consist of shadow creatures like shadows and wraiths that will approach from different directions.
  • Fallen Harpers & Pilgrims: Later waves will include fallen Harpers and pilgrims, adding variety to the enemies you face.
  • Vines & Ravens: Some enemies will emerge near the portal, including grasping vines and ravens with minimal health.

Portal Integrity:

  • Priority: The enemies’ main goal is to damage the portal, and if it sustains too much damage, the portal will close, leaving Halsin trapped in the Shadowfell.
  • Turn Count: You have four turns to defend the portal. If you manage to prevent its destruction throughout this time, you’ll succeed in this phase of the quest.

Tips For Success

  • Focused Attacks: Prioritize attacking enemies that are close to the portal to minimize their impact on its integrity.
  • Healing & Buffs: Keep your party members healed and use buffs to enhance their survivability and combat effectiveness.
  • Retreat If Needed: If a character’s health is critically low, consider temporarily retreating them from the front lines to avoid unnecessary risks.

If you successfully defend the portal for four turns, Thaniel will arrive alongside Halsin, and any remaining enemies will be defeated. After this phase, the quest will progress, and you’ll move forward in your journey to rescue Baldur’s Gate 3 Thaniel and lift the Shadow Curse. 

Locating Thaniel’s Missing Half

My Thoughts On The Thaniel Quest

The rescuing Thaniel quest is one of the best examples of strategy over brute force in a game like Baldur’s Gate 3. In almost all of my playthroughs, I used Shadowheart’s “Turn Undead” spell to eliminate a great number of Shadows in just one turn.

Additionally, rescuing Thaniel is the final step to getting Halsin as a companion, which is always a fun experience. Granted, you need to pass a lot of checks and fight a lot of battles in this quest line, but hey, you get to remove the Shadow curse from the lands. That ultimately means, no more Pixie begging for you to be their friend.

With Thaniel and Oliver’s reunion, this guide concludes its journey through Baldur’s Gate 3. From battling shadow-cursed enemies to rekindling companionship, your choices echo the fate of Thaniel’s world. The looming encounter with Ketheric Thorm promises a gripping finale. Before you go, kindly spare a moment to delve into our guides regarding the Cleric Class and the Wildheart Barbarian.
