The Leviathan

The Leviathan is a large sea creature found within the Scar, who is encountered during Desert Treasure II - The Fallen Empire. Once dwelling in the Eastern Sea, the Leviathan was inadvertently dragged into the Scar during the Battle for the Eye when Perseriya accidentally opened an abyssal rift in an attempt to teleport reinforcements in.

It has since then adapted to the abyssal environment and has made itself at home in a large lake within the Scar, preying upon those who were unfortunate enough to be pulled into the Scar during the battle. This is seen clearly on accounts of survivors and what remains of the Zarosian fleet in the area.

The Leviathan is best fought with ranged; attempting to attack The Leviathan with melee will result in the following message: Your melee attacks can't reach the lure! The boss fight is initiated upon climbing into the arena, where it will use a volley of rapid-firing attacks which deal damage upon impact; protection prayers will fully block these attacks.

The Leviathan will attack with random volleys of mage, range and, melee orbs at varying attack speeds throughout the fight. At the end of each volley, the boss will roar and cause debris to fall onto the player, potentially restricting movement and obstructing line of sight. Every subsequent volley of attacks will increase in intensity, which can become difficult to switch prayers for unskilled players at later volleys. The boss can also bite players in the tiles right next to the pool, which deals melee damage.

At any point during the sequence, players can cast shadow spells to stun the Leviathan (which will always succeed), where it will stay still for a small amount of time. Damage against it is capped at 10 when stunned, but the player can run around to attack its backside to deal a large amount of damage, which will cause it to retaliate with a special attack. This also resets the Leviathan's attack speed to the beginning of the 2-tick attacks.

Upon reaching 180 hitpoints, the Leviathan will begin the enrage phase. Its attack speed will now stay at two ticks, losing the ability to launch orange orbs (but still being able to bite players) while an abyssal pathfinder will spawn to the north-west of the arena (or the next clockwise direction if the spawn point is blocked by debris) and will begin to move clockwise. The player must stay within the pathfinder's Area-of-Effect for a significant accuracy and damage boost until the boss is defeated.

When the Leviathan is defeated, a drop will be rolled for until the roll results in a success, as described below:[1]

In addition, defeating the boss perfectly will earn 50% more loot from the standard drop table,[2] which requires the player to do the following:

If the player is no longer in the same instance when the boss dies, either due to teleporting out or by dying at the same time, no loot roll is made, and no progress can therefore be made on the vestige drop.[3]

Drop rates estimated based on 387,013 samples from the Drop Rate Project, unless otherwise cited.

There is a 1/96 chance of rolling the unique drop table per kill. After hitting the table, there is a 1/8 chance to get a piece of the Virtus robes (then a separate 1/3 roll to determine which piece), a 3/8 chance to get a single vestige roll (it will drop on the third such roll), a 3/8 chance for a chromium ingot, and 1/8 chance for the Leviathan's lure. Below lists the effective drop rates.

The items are rolled in the following sequence: awakener's orb, scarred tablet, smoke quartz. These items will replace the normal loot rolls.

These supplies are all dropped together.
