Players must navigate through ruins where the path is often blocked by rising tides or debris. Understanding the layout of the Fold Realm is the first step toward confronting the shadows of the Round Table and claiming the throne.

The Pendragon Legacy: Arthur vs Mordred

In the world of tides of annihilation king arthur, the title of "Pendragon" is more than a name—it is a source of immense, albeit dangerous, power. The narrative focuses on the clash between those who seek the throne for power and those who seek it for restoration. Mordred, the primary antagonist of this arc, views himself as the only one destined to wield this power, dismissing others as mere "bugs" or "discarded pawns."

The Gwendolin Perspective

  • Motivation: Protecting the realm from instability.
  • Combat Style: Balanced, focusing on precision strikes.
  • Key Strength: Resilience against the Scarlet Waters.

The Mordred Perspective

  • Motivation: Total dominance and the throne.
  • Combat Style: Aggressive, high-damage AOE spells.
  • Key Strength: Manipulation of the Fold Realm's energy.

The conflict culminates in a trial of strength where the player must prove their worthiness. Unlike traditional Arthurian tales, this version of the legend incorporates the "Tides" mechanic, where the environment itself fights against you.

Defeating the Pendragon Boss: Step-by-Step

The encounter with the self-proclaimed Pendragon is the peak of the tides of annihilation king arthur experience. This fight is divided into three distinct phases, each requiring a shift in strategy.

1

Navigate the Flooded Path

Before the fight begins, you must reach the arena. Knock down the stone pillars to cross the Scarlet Waters. Do not linger in the water for more than 3 seconds, or the instability debuff will stack, reducing your movement speed by 50%.

2

The Illusion Phase

Mordred will use "Cheap Tricks" to create clones. Look for the clone that does not have a shadow; this is the real boss. Attacking the wrong clone will trigger a counter-attack that drains your mana.

3

The Despair Phase

Once Mordred reaches 30% HP, he will invoke the "True Power of Pendragon." The screen will turn dark, and he will launch massive energy waves. You must hide behind the remaining pillars to survive this phase.

4

The Final Strike

When the darkness clears, Mordred is briefly stunned. This is your window to use your Ultimate ability. Ensure your "Fold Realm" resistance is active to maximize damage during this window.

Boss AttackDamage TypeHow to Avoid
Scarlet WaveMagic / CorruptionJump over the low-flying projectile

Critical Warning

Do not attempt this fight without at least 40% Corruption Resistance. The Scarlet Waters in the arena will otherwise kill you before the second phase begins.
