The 'On the Run' mission is a pivotal moment in the Lightfall campaign, featuring a climactic confrontation with the corrupted Cabal Emperor, Calus, now a Disciple of the Witness. This boss fight tests your mastery of the new Strand abilities and your ability to adapt to Calus's overwhelming power. Successfully navigating this encounter is crucial for progressing the narrative and understanding the true threat posed by the Witness.

As you progress through the 'On the Run' mission, you'll find yourself in a visually striking and chaotic arena. Calus, in his transformed state, is a formidable opponent. He utilizes a combination of powerful Cabal weaponry, dark energy attacks, and the ability to summon reinforcements. Your primary objective is to survive his onslaught while finding opportunities to deal damage and exploit his weaknesses. This fight is designed to showcase the power of the Witness's influence and the desperation of Calus.

Calus's Attack Patterns and Weaknesses

Calus's attack patterns are varied and designed to overwhelm unprepared Guardians. He frequently employs:

Massive Energy Blasts: Calus will unleash devastating beams of energy from his weapon. These are often telegraphed, giving you a brief window to dodge or take cover.
Summoned Forces: He will periodically summon waves of Cabal soldiers and Tormentors to support him. Prioritizing these adds is crucial to prevent being overwhelmed.
Ground Pounds and AoE Attacks: Calus can slam the ground, creating shockwaves, or unleash area-of-effect attacks that cover large portions of the arena.
Dark Energy Manipulation: As a Disciple, Calus can manipulate dark energy, creating hazardous zones or empowering his attacks.

Calus's primary weakness during this fight is his reliance on specific mechanics that expose him to damage. You'll need to observe his attack patterns closely to identify these windows. Often, after a major attack or when he is vulnerable, he will present an opportunity for you to strike.

Utilizing Strand Abilities Effectively

The 'On the Run' mission is a prime opportunity to practice and master your Strand abilities. The grappling hook, in particular, is invaluable for:

Mobility: Quickly repositioning to avoid Calus's devastating attacks.
Reaching Cover: Using the grapple to ascend to higher ground or reach protective structures.
Evading Adds: Swiftly escaping swarms of summoned enemies.

Your Strand Super ability, when available, can also be a significant asset. Use it strategically to deal burst damage to Calus or to clear out a large group of his summoned allies, creating breathing room for you to focus on the main threat.

Phase-by-Phase Strategy

The fight against Calus typically progresses through several phases, each increasing in intensity:

Phase 1: Initial Assault: Calus will begin with a barrage of his standard attacks. Focus on dodging, taking cover, and eliminating any summoned adds. Look for opportunities to chip away at his health.
Phase 2: Increased Pressure: Calus will become more aggressive, utilizing more powerful attacks and summoning tougher enemies. This is where effective use of your Strand abilities and Super becomes critical.
Phase 3: The Final Stand: As his health dwindles, Calus will unleash his most devastating attacks. You'll need to be precise with your dodges and attacks to finish him off before he can overwhelm you. Pay close attention to any visual cues that indicate his final, desperate moves.

Recommended Loadouts

For this encounter, a balanced loadout is recommended. Consider:

Primary Weapon: A reliable auto rifle or pulse rifle for dealing with adds and maintaining consistent damage.
Special Weapon: A shotgun or fusion rifle for close-to-mid-range burst damage when you have an opening.
Heavy Weapon: A rocket launcher or linear fusion rifle for maximizing damage during vulnerable phases.
