Granado Espada M: Rebel Keith R7 Headless Knight Boss Guide

To defeat the Rank 7 Headless Knight in Granado Espada M, anchor Rebel Keith at maximum firing range behind a dedicated frontline tank, face the boss away from the team, and sidestep horizontal charge vectors while cycling armor-penetration skills.

The Rank 7 Headless Knight relies on high physical mitigation, heavy block rates, and lethal point-blank area attacks. Rebel Keith bypasses these defenses by delivering sustained ballistic damage and armor penetration from outside the boss’s melee range, avoiding knockdowns that disable standard frontline attackers.

Headless Knight Combat Mechanics

The boss telegraphs dangerous frontal sweeps, ground shockwaves, and barrier buffs. Recognizing these cues prevents squad wipes and maintains Keith's damage output.

Boss Ability	Hazard Profile	Recommended Counterplay
Spectral Cleave	180-degree frontal melee arc that inflicts heavy knockback	Direct the tank to turn the boss away from the party; keep Keith on the flank or rear
Abyssal Stomp	Circular ground shockwave causing stun and armor reduction	Step out of the red ground perimeter immediately during the windup animation
Phantom Charge	Fast forward dash aimed at the highest threat or a distant target	Sidestep Keith horizontally perpendicular to the dash path rather than backpedaling
Fortified Bastion	Temporary damage-mitigation barrier	Fire Keith’s high-penetration active skills to break the shield before the timer expires

Phantom Charge is the primary threat to Rebel Keith. If the boss pauses and dips its shoulder, it is preparing to charge down that lane. Moving Keith sideways immediately avoids the extended hit box at the end of the dash.

Recommended 3MCC Squad Setup

Using the 3MCC system, pair Rebel Keith with a frontline anchor and an offensive buffer to stabilize boss positioning and increase clear speed.

Main Tank (Defensive Specialist): Run a sword-and-shield guardian to hold taunt in the center of the arena and face all frontal sweeps away from the team.
Support Buffer: Bring a dedicated support character to apply movement speed, attack rating, and armor penetration buffs. Movement speed is critical for manual dodging.
Rebel Keith (Heavy Firearm Stance): Set Keith in his single-target firearm stance to maximize penetration and firing range. Keep him locked at maximum distance so he never triggers proximity hazards.

Step-by-Step Boss Execution

Engage with the Tank: Send your tank into the encounter space first to absorb the opening swing. Land an initial taunt and pivot the boss 180 degrees away from the entry point.
Position Rebel Keith: Move Keith to the outer perimeter at maximum firing range. Wait until the boss settles its aggro onto the tank before attacking to avoid pulling early aggro.
Cycle Armor-Piercing Skills: Fire Keith’s standard rotation into the boss's flank or back. Reserve his highest burst skill for when the Headless Knight casts Fortified Bastion to break the barrier quickly.
Dodge Phantom Charge: If the boss locks onto Keith and lowers its shoulder, issue an immediate manual move command perpendicular to the charge lane.
Reset Aggro and Repeat: Have the tank re-establish taunt and turn the boss away before Keith resumes full skill cycling. Repeat this rotation until the boss is cleared.

Gear Priorities for Rebel Keith

Focus Rebel Keith’s build on penetration and mobility rather than flat defensive stats:

Weapon Attributes: Prioritize armor penetration, critical hit rate, and bonus damage against armored targets to overcome the boss’s innate physical defense.
Accessories: Prioritize movement speed and evasion over minor flat defense or health boosts. Rank 7 boss abilities can defeat a ranged attacker in a single hit, making manual avoidance far more valuable than damage mitigation.
