How to Defeat the Harbinger

Learn the best strategies to defeat the Harbinger in Halo Infinite. This guide covers boss stats, weaknesses, phases, and combat tactics for this challenging encounter.

Stats / Weaknesses:

• The Harbinger teleports frequently, creating small windows for attack.
• She summons energy balls that inflict massive damage; these appear as small blue lights before firing.
• Her shield must be depleted before she can be damaged.
• When her shield is down, she is vulnerable for one or two hits, but can only lose up to 50% of her health per vulnerable phase.

Phases:

1. Phase 1: Enemy Waves - Defeat waves of Brutes, Jackals, Grunts, and Skimmers. Save power coils for later.
2. Phase 2: Harbinger Engagement 1 - Deplete the Harbinger's shield, damage her slightly, and she will retreat.
3. Phase 3: Enemy Waves 2 - Defeat another wave, including a Brute Officer. Aim for the head.
4. Phase 4: Harbinger Engagement 2 - Deplete her shield again, damage her, and she retreats.
5. Phase 5: Enemy Waves 3 - Face an Elite Brute with heavy armor and a melee weapon, along with other enemies. Use the Grappleshot to evade the Elite. Consider weapons with high AoE damage like the Cindershot. Use blast coils strategically.
6. Phase 6: Harbinger Engagement 3 - Deplete her shield one final time and finish her off while she is vulnerable.

Strategy:

• Keep your distance to better anticipate the Harbinger's teleportation and energy ball attacks.
• Use powerful weapons for quick eliminations of regular enemies.
• When facing the Elite Brute, use the Grappleshot to quickly move between cover and avoid its melee attacks.
• Target the Elite Brute's head for quick takedowns.
• The Cindershot is effective against the Elite Brute and can briefly stun it.
• Kite enemies towards blast coils and detonate them for area damage.
• After defeating the Harbinger, you will unlock the 'Set a Fire in Your Heart' and 'Too Many Goodbyes' achievements.
