Sar'Thuun is a huge tentacled creature with one great eye that guards a team's base from a pool of water. It never moves. It attacks enemies who come into its lair with its tentacles, a beam from its eye and orbs spat from its maw, and fights for the team whose base it guards.

Where it appears

• In Service, each team has its own Sar'Thuun, and killing the enemy team's one wins the match. See the game mode page for how a boss works there.
• On Darkcove it sits in the pool at the center of each team's base.
• On Academy one waits in the catacombs for practice.

Health

Its health and how quickly it heals are set by each map; see the map's page. It heals itself only after nobody has hurt it for a few seconds, so a team that keeps up the pressure keeps the damage it has done.

Only the enemy team can hurt it. Every weapon works on it: bullets, pellets, rockets, grenades, flames and melee. Buildings hurt it too.

Weak point

The great eye on top of its body takes double damage. A hit on the eye shows and sounds like a headshot.

Attacks

Sar'Thuun attacks only enemies inside its lair that its eye can see, including their buildings. It uses one attack at a time, each with its own cooldown, and rests for 1.2 s between attacks. Which attack it picks depends on where its enemies stand:

• Enemies close to it, in reach of its tentacles: the tentacle sweep.
• A single enemy farther out: the eye beam.
• Two or more enemies farther out: the orb volley.

It holds a grudge: the eye beam and the first orb of a volley go for whoever has hurt it most in the last few seconds.

Tentacle sweep

A tentacle sweeping low across the floor

A tentacle rises and winds up, then sweeps a wide, low arc around one side of it, about 150 degrees across and reaching about 9 m. An arc is drawn on the ground while it winds up.

• Wind-up: about 0.8 s before the strike.
• Damage: 70, once per sweep, so a player at full health survives one.
• Knockback: throws you outward and up at 14 m/s.
• It sweeps at about waist height: jumping over it at the right moment avoids it.
• Cooldown: 4 s.

Eye beam

The eye beam

The eye locks onto one enemy and charges with a growing glow, then fires a beam at their chest.

• Charge: 1 s, during which the eye follows its target closely.
• Firing: 1.5 s, dealing 50 damage per second, so at most 75 damage.
• Reach: 45 m. Walls and other solid cover stop it.
• Turn speed: while firing, the beam turns toward its target at only 40 degrees per second. Strafing close to it outruns the beam; standing still or moving straight away does not.
• Cooldown: 6 s.

Orb volley

The maw open for a volley

Its maw opens and spits three orbs, 0.8 s apart, each lobbed at the feet of an enemy between 8 m and 32 m away. Where each orb will land is marked on the ground as soon as it is thrown.

• Flight: 0.9 s to 1.4 s depending on distance, which is your warning to move.
• Damage: up to 65 where it lands, less the farther you are, and none past 3.5 m.
• Knockback: throws you at up to 12 m/s.
• An orb thrown at an enemy who then dies or leaves still lands where they were.
• Cooldown: 7 s.

Fighting it

• Shoot the eye. Long-range weapons such as the Sniper Rifle, or a steady stream from the Minigun, do twice their damage there.
• Stay out of tentacle reach, about 9 m, unless your build relies on close range. If you do go in, watch for the arc on the ground and jump the sweep.
• Strafe when the eye charges, and break line of sight if you can: the beam turns slowly and stops at cover.
• Spread out. Bunched attackers invite volleys, and every orb's landing spot is shown, so keep moving once orbs are in the air.
• Its eye beam and first orb go for whoever hurt it most lately. A teammate who draws its attention lets everyone else fire freely.
• Healing weapons such as the Mender keep a push going through the sweeps and orbs, and a Dispenser just outside the lair gives a place to fall back to.
• Keep up the damage: once it goes a few seconds without being hurt it starts to heal.

Defending it

• It fights for you, but it only attacks enemies inside its lair, so meet attackers before they get there.
• Attackers hurting it are easy to find: you are warned when your boss comes under attack.
• Push attackers into tentacle reach, or knock them in. A defender who stands between the attackers and the pool also draws fire away from it.
• A Sentry covering the lair adds steady damage to whoever the boss is fighting.
• Driving attackers away gives it time to heal back what they did.

When it dies

It collapses and sinks into its pool. In Service, the team that killed it wins the match at once. On Academy it comes back a few seconds later.

Players killed by it show "Sar'Thuun" in the kill feed and on the kill cam. Kills by it are not credited to any player.

Voice lines

While Sar'Thuun is alive and guarding your team's base, it now and then whispers to you. The whispers are quiet and seem to come from inside your head, and only you hear them. Each player gets their own timing and order, and the last four lines are not repeated right away. The closer you stand to it, the more often it speaks: about every 6 to 14 s right beside it, and about every 30 to 60 s from far across the map.

It speaks only to its own team, and it has 20 lines:

#	Line	Length
1	"Your heart will explode."	6.0 s
2	"Your friends will abandon you."	5.6 s
3	"One by one."	5.3 s
4	"Your reality is but an illusion."	6.9 s
5	"I see all."	5.3 s
6	"Your teammates will abandon you."	6.0 s
7	"Your agony feeds my essence."	7.3 s
8	"You are already dead."	5.6 s
9	"I am everywhere and nowhere."	6.8 s
10	"Such innocence."	3.7 s
11	"You serve me."	5.7 s
12	"Your eyes are mine."	5.5 s
13	"I can see your thoughts."	5.0 s
14	"I hunger."	3.8 s
15	"They will betray you."	5.8 s
16	"Dream with me."	4.3 s
17	"Your life can end."	5.3 s
18	"You are sleeping."	5.1 s
19	"Kill them."	3.5 s
20	"I can see your consciousness."	5.8 s
