To beat the Abaddon boss, located at the top of the Parking Tower in Eidos 7 during the “Scavenger Adam” main quest, focus on parrying its sword attacks and using Blink to counter its blue moves. In its second phase, which begins when its health drops below 60%, prioritize dodging its unparryable yellow lightning and projectile attacks.

Abaddon Overview

Abaddon is the second boss encountered in Stellar Blade, a large creature wielding two long swords and capable of thunder-based attacks. It is an Elite Naytiba found in the Parking Tower of Eidos 7 as part of the “Scavenger Adam” main mission. The creature’s appearance, described as having a body split open, random spikes, and circular horns emitting electricity, is why it is named Abaddon. The fight is divided into two distinct phases, with a significant shift in its move set and abilities once its health falls below 60%.

Phase 1 Strategies (Above 60% HP)

During the initial phase, Abaddon primarily relies on its two long swords for attacks. A key strategy is to always counter its first move with Blink. Abaddon’s regular attacks often involve quick, multi-hit sword combos that are best handled by parrying.

Attack NameCounter MethodNotes
Double Slice (running scream)BlinkAvoids the double slice, stuns Abaddon for a few seconds.
Regular Combo (two-hit with left hand)ParrySecond blow after a small jump; parry both hits together.
One-Two (after swords together)ParryFaster combo than the regular two-hit.

One crucial environmental interaction in this phase involves the oil barrels scattered around the arena. If Abaddon is near these barrels, you can cause them to explode, dealing a significant chunk of damage to the boss. However, be cautious as these explosions will also harm Eve if she is too close. Utilizing these barrels effectively can provide an early advantage in the fight. Remember to use your Beta skills as soon as they are charged, as they can interrupt Abaddon’s attacks and push it back, providing crucial breathing room or damage opportunities.

Phase 2 Strategies (Below 60% HP)

The second phase of the Abaddon fight begins once its health drops below 60%. This transition is signaled by a dynamic camera movement and Abaddon hitting the floor, gaining an electric buff. Immediately after this, run away to avoid the initial floor impact. In this phase, Abaddon gains new electric and projectile attacks, and its previous sword attacks may become electrified, dealing more damage. Yellow attacks cannot be parried and require precise dodging.

Attack NameCounter MethodNotes
Lightning Bolts (yellow)Sprinting / Continuous MovementCircles on the floor indicate landing zones; move continuously to avoid.
Big Jump (yellow)Perfect Dodge / Sprint OutEnds in a ground blow; requires precise evasion.
Slash Projectile (yellow)Perfect Dodge / Sprint OutLong-range forward projectile.
Four Consecutive Spark Balls (yellow)Sprinting / Continuous MovementOriginate from its head; easily dodged by running to the sides.
Double Slice Forward, Jump Back, Charge (regular)ParryA new variant of its sword combo.
Two-Hit Combo, Jump Back, One-Two (regular)ParryAnother new sword combo variant.
Quick Jump (three-hit)ParrySimilar to first phase quick jump, but with an added third blow.

During this phase, it is critical to distinguish between parryable regular attacks and unparryable yellow attacks. For yellow attacks, Perfect Dodge is recommended when possible, but for projectiles like the small spark balls and lightning bolts, simply sprinting to the sides is often sufficient. Continue to utilize Beta skills when available to interrupt attacks or deal burst damage. The fight concludes with a dynamic cutscene requiring an L1 press.
