Deadlock Mid Boss Guide: Rejuvenator, Timing & Steals

🎯 The core idea

The Mid Boss is the objective that decides most Deadlock games. Taking it is about timing, not damage: go after a won fight or a pick, with your waves pushed and a comp that can secure the Rejuvenator. Fighting over it is about knowing when the enemy will start, choosing your entrance and using a punch-and-parry pattern to steal credits from them.

• free costs nothing
• cheap small cost
• setup needs preparation
• grind pays off slowly
• skip the thing to stop doing

This guide is built on FredTheFinch's "How to ACTUALLY Win Midboss" (January 2026). He is a high-rank Yamato player known for stealing Rejuvenators. Every number was checked against deadlock.wiki on 2026-10-19. The video came out before several Midboss patches and before City Never Sleeps, and where the wiki disagrees with it, the wiki's number is used and the change is named. The Macro and Objectives guides cover the Mid Boss in a paragraph each. This one goes deeper.

What the Mid Boss is and where it lives

The Mid Boss (the wiki spells it Midboss, and the damage report calls it the Temple Guardian) lives underground in the sewer pit in the center of the map, under Times Square. It is up from the very start of the match. The video says it spawns at 10 minutes, but the wiki records a May 22, 2026 change that made it start spawned at the beginning of the game. While it is alive, a golden Rejuvenator symbol marks the Mid Boss location on the minimap. The entrances to the pit are marked with the same symbol along Broadway.

It only fights back against heroes inside its pit. It fires a bright purple laser beam at the closest player in the pit. The Mid Boss laser deals weapon damage, so bullet resist helps. Heroes outside the pit can't damage it at all, which is why every Mid Boss fight happens in the same small room.

Two of these differ from the video. The wiki puts base health at 13,000, not the 11,900 the video quotes, and the global roar now happens at 50% health instead of 70%. Both changed on March 6, 2026. The 195 HP per minute growth still matches. The shield matters more than it looks: it soaks a fixed chunk of every hit, so a few weak attackers barely hurt it, while a full team or one gun carry breaks through it easily. During the fight its health bar appears at the top of your screen, as in this frame.

Mid Boss rewards: souls, permanent buffs and the crystal

The Mid Boss rewards are why teams risk so much on it. Killing it gives the killing team 3,000 souls (+50 per minute) and 2 permanent buffs for every player, according to the wiki. Then a single Rejuvenator crystal starts dropping into the pit. The kill feed in this frame shows the kill credited to the Temple Guardian.

The souls and buffs go to the team that lands the kill, so the last hit decides who gets the bounty. If you are contesting, you can still deny the bounty by killing the enemy before the boss dies, but you can't take the souls by stealing the crystal. The crystal is separate: either team can claim it, whoever killed the boss. That is why stealing is possible at all.

The video describes three Rejuvenator crystals. Since August 2025 the wiki describes one crystal that you hit up to three times. Each heavy melee is one credit, so the play is the same, but you are fighting over one spot, not three.

How the Rejuvenator crystal and its credits work

The crystal takes 6 seconds to land (the video says 7, but the wiki records the March 2026 cut to 6). It can't be targeted while it falls. Once it lands:

• Each heavy melee on it gives your team one Rejuvenator credit, up to 3 per Mid Boss kill. A light melee does nothing.
• The first player to hit it heals to full.
• A heavy melee can be parried. A successful parry stuns the attacker for 2.75 seconds (debuff resistance doesn't shorten it) and makes them take 25% more damage. That one rule shapes every steal and every secure.

The Rejuvenator buff itself, per the wiki:

• Each credit is one in-place revive. When a player with the buff dies, they come back after 3 seconds at full health where they died (or on the ground below if they died in the air).
• One credit per player. Each player can use only one. If you die a second time, you respawn normally even if your team still has credits.
• The Rejuvenator buff lasts 3 minutes (cut from 4 in June 2026), with a warning at 30 seconds left. It ends early once every credit is used. Hitting the crystal again later doesn't refresh it.
• A kill on a hero who revives this way gives no souls and doesn't show in the kill feed. It still triggers "on hero kill" effects.
• While waiting to revive, the player counts as dead. They don't contest the Unstable Rift and don't count for ally presence effects.

The Rejuvenator buff no longer gives bonus stats. Old footage, including some clips in this video, shows +15% fire rate, +15% damage and +10% health. The wiki says those were removed on November 21, 2025.

Mid Boss respawn time and the HUD indicators

The Mid Boss respawn time is the one number the video and the wiki agree on: 7 minutes after the first kill, 6 after the second, then 5 minutes after every later kill. A respawn is announced with a roar and the Herald saying "Midboss has arrived." The Rejuvenator symbols over the pit entrances glow again when it is back.

Tracking the Mid Boss timer:

• Minimap: the Mid Boss icon fills up as the respawn approaches. Press Tab for the exact time left in minutes and seconds.
• Top bar: the top HUD bar shows how many Rejuvenator credits each team has left. Teammates who haven't used their credit get a highlight under their net worth. Use that highlight to see who can afford to dive.
• Health bar: when you are near the fight, the Mid Boss health bar shows at the top of the screen, so you can see how close it is to dying before the roar.

City Never Sleeps (September 29, 2026) reworked the HUD. The official notes only say "Major UI changes", and the wiki's Midboss page still describes the minimap fill and Tab timer, so this guide doesn't list each new widget. If your build shows a Mid Boss countdown in the top bar, it counts the same 7/6/5 minute Mid Boss timer. This frame is from before the patch. It shows the "Heavy Melee to claim Rejuvenator" prompt and the "Captured Rejuvenator" line in the event feed.

When to take the Mid Boss

Taking the Mid Boss costs most or all of your team and a good chunk of time. You need two things: time (the enemy can't punish you for being away) and space (they can't contest the pit). Here is when to take the Mid Boss:

• free Right after you win a team fight. Six against two is the easiest Mid Boss there is. The enemy can't contest the pit or punish your waves.
• setup With a smaller lead and good waves. You don't need a full wipe. A single pick with your lanes pushed in can be enough. The smaller the lead, the more the securing plan matters.
• skip Don't start it while your waves are crashing into your own Walkers. You will probably lose the Walker while you are in the pit. Sometimes that trade is worth a Rejuvenator, but make it on purpose.

The video's point about damage still holds. The boss gains health over time, but your team's damage grows faster, so it dies quicker the later the game goes. Since it is now up from the start, early takes are possible on paper. In practice, early teams can't break the shield and health fast enough for the trade to be safe.

Team comp: who kills it fast and who secures it

You need to ask two separate things about your comp: how fast it kills the Mid Boss, and how well it holds the crystal.

Kill speed. Gun builds melt objectives. The video's example is Wraith: with her up, you can take the boss earlier and spend less time in the pit. Heroes like Yamato or Dynamo add much less damage to the boss itself.

Securing and contesting. The video names the heroes that matter most for Mid Boss fights:

Items count too: Curse (silences, disarms and blocks item use), Silence Wave and Unstoppable (immunity to stun, silence, sleep, root and disarm, which includes a parry stun).

The video gives an example. Going 4v3 with good waves, a 10k soul lead and a Wraith is still risky if the enemy has Yamato and Dynamo ultimates and you have nothing to answer them. Swap those two heroes to your side and the same Mid Boss is almost free. Counters also cancel out: a Yamato ultimate, several Unstoppables or a Lash on your side can make a Mid Boss playable into an enemy Dynamo. There is no simple formula for this. It is something you learn from experience.

How to tell the enemy is starting the Mid Boss

Late in the game a gun-heavy team can kill the boss in seconds, and the roar now comes at 50% instead of 70%. If you wait for the roar to rotate, you are too late. You have to see it coming:

• Turn the "when to take it" checklist around. If they have a player advantage, pushed waves and a comp that kills it fast, assume they want the Mid Boss.
• free Read the minimap. A team in the pit is invisible on the map. If they are ahead and their waves are crashing, but nobody is showing, they are probably in the pit. If heroes go missing from the map, there is usually a reason.
• Call it early and often. The video's view is that you can choose when your team starts, but the enemy only needs a good enough chance. So call "they might do mid" at any hint and set up. You will often prepare for nothing, but being overprepared is better than arriving late.

Setting up doesn't always mean fighting. If you can't win the pit, use the time they spend there to split-push or take something else.

Choosing your entrance into the pit

Most players skip this step. If you arrive at the last second, take the fastest way in. If you saw it coming, pick your entrance to surprise them. Players who come in through the usual entrances walk straight into silences and cooldowns that are already waiting for them.

The video ranks the entrances like this:

1. Their side, through the rope shaft. They won't be watching it.
2. From above.
3. The side entrances.
4. Your own side.

Go in from whichever one you can reach with the most value. One caveat: the video's routes are from the pre-City Never Sleeps map. The wiki still lists the Broadway entrances marked with the Rejuvenator sign and the rope shafts that lead to the upper area of the pit, but check the current layout in a sandbox before you rely on a specific path.

Three ways to contest a Mid Boss

Once you have decided to fight, pick one strategy from the three below and make sure your team knows which one:

• setup Kill them before the boss dies. If you win team fights and can arrive before the drop, fight them in the pit and take the boss yourself. This is the best answer when they have a Dynamo or Lash ultimate that makes the crystal impossible to steal. It needs everyone to go in at the same moment.
• setup Let them secure the crystal, then wipe them. If you are much stronger but can't arrive in time, wait for them to spend their cooldowns and health on the crystal, then go in. Kill enough of them and their credits are gone before they do anything with them. This is the hardest of the three.
• cheap Steal the crystal. The video's favorite. It depends least on your team, and a good player can take one, two or even all three credits alone. The next two sections cover how.

The punch-and-parry steal

First assume neither team has stuns or crowd control and it is just punches and parries. This is the video's sequence:

1. As the crystal comes down, stand right on top of it and wait.
2. Don't parry until you hear them punch. Some players punch as soon as it lands. Others wait on purpose to bait out your parry, and a missed parry has a 4.5 second cooldown (deadlock.wiki).
3. When you hear the heavy melee, parry, then parry once more.
4. Punch twice, then parry again, then punch again.

A parried heavy melee stuns the attacker for 2.75 seconds, and each heavy melee is one credit. That is why parrying first and then punching is how you steal the Rejuvenator from a team that should have won. In the video, this pattern regularly gets at least one credit, often two, sometimes three, even solo. It isn't guaranteed, and the timing changes as the players around you adapt.

With teammates he plays the same way unless you have a Dynamo or Lash ultimate that takes the enemy out completely. Doing your own sequence is more reliable than trying to coordinate everyone's cooldowns.

Stealing with Unstoppable, Yamato's ultimate or a stun

Cooldowns change the opening:

• With Unstoppable or Yamato's Shadow Transformation: punch first. Sometimes nobody parries the opening hit and you get a free credit. A parry can't stun you through either effect (the wiki says Unstoppable prevents the parry stun). Then go into the normal parry-and-punch rhythm.
• With a stun (a Doorman stun, Abrams' Seismic Impact, Ivy's Stone Form): stun, punch, then wait for their parry before you continue.

This frame shows Yamato's Shadow Transformation, the same tool the video is talking about. Remember the Mid Boss has 35% debuff resistance, but that only affects effects on the boss. The parry stun on players ignores debuff resistance entirely.

Securing your own Mid Boss

Securing your own Mid Boss works much like stealing. First choose one of two plans:

• setup Bait with the roar. If you are ahead but they still have big tools (a Yamato or Dynamo ultimate), bring it to the roar, then turn on whoever comes to contest and run them down. The whole team has to know you aren't actually killing it. One trap: if you make it roar and leave for a long time, it won't roar again when it gets low the next time. A team that comes back two minutes later gets no warning when they reach half health.
• Kill it and hold the crystal. This gives you more control than stealing. Decide in advance who punches first, who parries first and who holds the stun, so you can rotate them and make every steal attempt costly.

As a single player, look at their threats to the crystal and shut those down instead of punching:

• If you are Wraith and they have a Dynamo ultimate, play just outside the pit and kill the Dynamo before he gets in. The video says Wraith wins that 1v1 even if he dodges your ultimate with Quantum Entanglement. Or wait at the edge to Telekinesis him the moment he channels Singularity.
• Hold Curse or Silence Wave for the big ultimate instead of spending it early.
• With nothing to counter it, wait just outside for the Doorman stun or Abrams pin to go off, then jump in and parry.

Stopping their best tool is worth as much as landing the punch yourself.

What to do after you get the Rejuvenator

The video skips the full topic but gives one important rule: skip don't rush their base the moment you have credits. After a Mid Boss your waves are usually bad and half the team is low. Fix waves, heal and agree on a plan first.

Balance that against the clock: the buff now lasts only 3 minutes and each player has only one revive. A short reset is fine. Waiting through the whole window wastes it. Once the waves are fixed, push a Walker or the base while your credits are still up. The Macro guide's push thresholds (around 35–40k souls ahead, or ahead with Rejuvenator credits) fit this. Check the top bar's credit counter before you commit.

How this guide was fact-checked

• From deadlock.wiki (Midboss, Rejuvenator, Melee Attack, the Updates page and the update history pages, plus the item pages for Curse, Silence Wave and Unstoppable and the hero pages for Dynamo, Lash, Yamato, Abrams, Kelvin, Ivy, The Doorman and Wraith), checked 2026-10-19: health, regen, resists, shield, laser numbers, the 50% roar, the bounty and buffs, the 6 second drop, how credits work, the 3 minute duration, the respawn timer, parry stun length and cooldown, and every ability or item effect named here.
• From the video's own gameplay and commentary: when to take the Mid Boss, reading the minimap, the entrance ranking, the three ways to contest, the punch-and-parry sequence and the securing tactics. These are one high-rank player's methods, not rules from the game.
• Corrections to the video:
  • The Mid Boss is up from the start of the game since May 22, 2026, not from 10 minutes.
  • Base health is 13,000, not 11,900.
  • The roar is at 50% health, not 70%.
  • The crystal drops in 6 seconds, not 7.
  • There is one crystal hit up to three times, not three separate crystals.
  • The Rejuvenator buff has no stat bonuses since November 2025 and lasts 3 minutes since June 2026.
• City Never Sleeps HUD: the patch notes only list "Major UI changes". The respawn timer and credit indicators described here are from the wiki's current pages, not from a line-by-line patch note.

What this guide doesn't answer

• Exact entrance routes on the City Never Sleeps map: the map was reworked after the video. The wiki confirms the Broadway entrances and rope shafts, but not every new path.
• Full matchup charts for every hero at the crystal: this guide covers the heroes the video names. Other kits matter too, but listing all of them would be guesswork.
• Closing out a game after the Mid Boss: see the Macro guide for when to push the base and the Objectives guide for the Walker, Shrine and Patron order.
• Exact time-to-kill for specific builds: the video gives no numbers and the wiki doesn't list them, so none are given here.
