The Crassian Leviathan is the first boss inside of The Shadow Reef. After The Ambassador was informed by Oreb that the World Guardian was arriving with their allies, The Ambassador summoned the Leviathan and blessed it with Xau-Tak's power.

Strategies[edit | edit source]

The arena of the Crassian Leviathan.

The main head of the Crassian Leviathan is found at the north end of a small, rectangular arena. It uses melee and ranged auto-attacks depending on how far the player stands from it. The boss uses its auto-attacks before using one of its two special attacks. After the boss has used enough attacks, it will shift to the opposite end of the arena, forcing the player to move past the other leviathan heads and through the pool of poison. The extra leviathans are not attackable but can lunge at players, dealing unblockable poison damage and stunning them.

The Crassian Leviathan itself has a moderately high defence and has the ability to heal itself 3,000 life points for each player fighting it every several seconds. Three players will cause it to heal 9,000 life points every time it heals itself. Players can reduce this amount by poisoning it, using either weapon poisons or the effect of cinderbane gloves or the upgraded bone blowpipe, which reduces its healing to 1,000 per player.

Special attacks[edit | edit source]

The special attacks of The Crassian Leviathan include the Head Crash attack and the Acid Breath attack.

The Head Crash attack consists of the leviathan slamming its head in the ground, dealing multiple hits of high typeless damage. This can be avoided by running to either the far left or far right depending on which side the leviathan is crashing its head towards. After the first Head Crash it then immediately uses the Head Crash attack again in the opposite direction of the first attack.

The Acid Breath attack consists of the leviathan breathing a deadly cone of green acid in front of it with a coned area-of-effect radius, dealing rapid hits of 6,000 typeless damage. This attack can be easily avoided by standing to the sides of the Leviathan's head. It is used at the start of each of its attack rotations. This attack will hit the entirety opposite end of the arena, so players should stay within distance of the main head.

Trivia[edit | edit source]

  • The Leviathan's appearance is based on both the moray eel and the frilled lizard.
    • Due to this, it is the only known Crassian to not have a crustacean or cephalopod-like appearance.
  • The Crassian Leviathan is the only boss in all three Elite Dungeons that has no dialogue of its own; this is provided by the Ambassador, who briefly appears at the start of the fight to taunt the player.
  • Despite being a Crassian, the Leviathan drops reinforced dragon bones and the draconic visage, which are normally dropped only by dragons. This is likely due to Kranon's blessing of it.
