What are the best ways to use line-of-sight in Baldur's Gate 3 combat?

Line-of-sight (LOS) is a critical mechanic in Baldur's Gate 3 combat, as it determines whether characters can see and target enemies or allies with spells, ranged attacks, or abilities. Understanding and manipulating LOS can give you a significant tactical advantage, allowing you to control the battlefield, avoid unnecessary damage, and set up devastating attacks. HereÔÇÖs a detailed breakdown of how to use LOS effectively in Baldur's Gate 3.

First, letÔÇÖs explain the mechanics. LOS is determined by the gameÔÇÖs environmental geometry, including walls, obstacles, and elevation. If a character or enemy cannot see their target due to an obstruction, they cannot attack or cast spells on that target. This applies to both ranged and melee attacks, though melee attackers can often reposition to regain LOS. Spells and abilities that require a clear path, such as Fireball or Eldritch Blast, are particularly dependent on LOS. Additionally, some spells, like Fog Cloud or Darkness, can obscure LOS entirely, creating areas where targeting becomes impossible.

To use LOS effectively, start by positioning your characters before combat begins. Use the environment to your advantage by placing ranged characters, such as archers or spellcasters, on high ground. High ground not only provides a better view of the battlefield but also grants a bonus to attack rolls, making it easier to hit enemies. Melee characters should be positioned near choke points, such as doorways or narrow passages, where they can block enemy movement and protect your ranged allies.

During combat, always check the LOS indicator before making an attack or casting a spell. The game will show a red line if the path is blocked, indicating that the attack or spell will fail. If you see this, consider repositioning your character or using a different ability. For example, if your wizard cannot cast Fireball because of a wall, they might instead use Magic Missile, which does not require LOS. Alternatively, you can move your character to a better position, though this may cost valuable movement points.

One common mistake is failing to account for enemy LOS. Enemies will also use LOS to their advantage, hiding behind cover or using spells to obscure your vision. To counter this, use abilities that ignore or manipulate LOS. For example, the WarlockÔÇÖs DevilÔÇÖs Sight invocation allows them to see through magical darkness, giving them an edge in obscured areas. Similarly, spells like Faerie Fire can reveal hidden enemies, negating their cover.

Advanced techniques involve using LOS to control enemy movement and actions. For example, you can create a bottleneck by positioning your melee characters in a narrow passage, forcing enemies to approach one at a time. This limits their ability to flank or overwhelm your party. You can also use spells like Wall of Fire or Spike Growth to block off areas, forcing enemies to take longer routes or suffer damage. Another tactic is to use invisibility or stealth to break LOS entirely, allowing you to reposition or set up ambushes without being detected.

Related D&D rules and mechanics also play a role in LOS. In Dungeons & Dragons 5th Edition, the rules for cover and obscurement are similar to those in BaldurÔÇÖs Gate 3. Half-cover and three-quarters cover provide bonuses to AC and Dexterity saving throws, while full cover blocks LOS entirely. Understanding these rules can help you make better decisions in combat, such as targeting enemies with less cover or using spells that ignore cover, like Sacred Flame.

Specific examples and scenarios can further illustrate the importance of LOS. Imagine a battle in a dungeon where your party is ambushed by a group of goblins. The goblins are positioned behind pillars, giving them half-cover and making them harder to hit. To counter this, your wizard casts Fireball, which ignores cover and damages all enemies in the area. Meanwhile, your rogue uses stealth to break LOS and flank the goblins, gaining advantage on their attacks. By the time the goblins realize whatÔÇÖs happening, they are already overwhelmed.

In conclusion, mastering LOS in Baldur's Gate 3 requires careful positioning, awareness of the environment, and strategic use of abilities. By understanding the mechanics, avoiding common mistakes, and employing advanced techniques, you can turn the battlefield to your advantage and secure victory in even the toughest encounters.
