Behavior

The Lost Sentry is located in a large setpiece resembling a courtyard, with several walls to provide cover. Throughout his fight, the Spectral Sentry, an invincible enemy, will fly around the edges of the arena while taking shots at targets and occasionally dashing through the middle of the arena.

Uniquely, while he is an Event Boss and has a minimap marker, he has no Quest Arrow and is not required to close the realm.

The Lost Sentry cannot move and uses a wide variety of randomized attacks, but his attacks do not gain difficulty as he loses health, although the Spectral Sentry will move faster as his health lowers. In between attacks, he will have short invulnerability times.

His attacks are as follows (names are unofficial):

Paralyze Spiral Attack

The Lost Sentry fires a 4-armed spiral of Paralyzing yellow bullets that rotates clockwise. While this is happening, it will throw highly damaging Red Bombs in groups of 8, alternating between throwing them in a tight ring around itself and throwing them in a wider ring to hit faraway targets.

Red Rings Attack

The Lost Sentry fires several dense, slow rings of red bullets that Armor Break, with a small opening on one side of each ring where players can dodge through. He will also be throwing Petrifying White Bombs in groups of 4, alternating between throwing them in a plus-shaped (+) or X-shaped formation.

Rapid Spiral Attack

The Lost Sentry fires 3 different 2-armed spirals of shots, consisting of purple, blue, and grey bullets. These spirals will rotate in different directions at a fast speed.

Rapid Spiral Attack 2

The Lost Sentry will fire 2-armed spirals of both red and blue shots, rotating in opposite directions. While doing this, he will also fire radial bursts of grey shots that move in a wavy pattern.

Crossing Streams Attack

The Lost Sentry will fire streams of black bullets in several directions that will curve into helical streams. In the meantime, he will target the nearest player with a highly damaging spread of green bullets.

Wavy Streams Attack

The Lost Sentry will fire wiggly streams of shots in all directions, alternating between black, purple, and yellow bullets. Beware especially of the yellow bullets: tanking one will result in being Paralyzed and being forced to eat the rest of the stream, causing immense damage and likely death.

Boomerang Spread Attack

The Lost Sentry fires several 3-round shotguns of green bullets along with pairs of grey bullets aimed in the opposite direction, all of which have a Boomerang property. His aim is not targeted, instead being aimed in a set direction before rotating clockwise.

Uniquely for a boss, the Lost Sentry visually begins breaking down as he loses health, the first change occuring at about 75% HP, the second at about 50%, the third at about 25% and the final at about 10%. Every time he breaks down more, he gains several seconds of invulnerabilty.

Tips and Strategies

While the Lost Sentry has enormous health and huge amounts of firepower, the Spectral Sentry defending him is arguably the most dangerous part of the fight due to its invincibility and armor-piercing shotguns. Avoiding the Spectral Sentry should be your highest priority.

Beware, as the Spectral Sentry will sometimes fly through the middle of the arena without warning.

The Lost Sentry’s attacks are powerful but heavily patterned: find gaps in his bullets and exploit them.
