Abyssal pathfinder - OSRS Wiki

The abyssal pathfinder is a glowing orb that spawns when The Leviathan is under 20% health in both modes. The pathfinder has a 3x3 tile radius in the normal encounter, and a 5x5 tile radius in the awakened encounter. Players should stand within its range to prevent the Leviathan's attacks from causing chip damage, along with providing an accuracy buff that will prevent the player from hitting below a certain threshold.
