Jeff is the only Strategist whose healing is a constant stream you can walk around with, and the only hero in the game who can swallow the entire enemy team. He is rated 1/5 difficulty for a reason: hold left click, drop bubbles, and your team stays alive. The skill ceiling is entirely in Hide and Seek management and knowing when It’s Jeff is a play instead of a throw.

Role and difficulty

Strategist. Jeff the Land Shark has 250 health. Difficulty Easy (1/5). He stands close to his team where Joyful Splash and Healing Bubbles reach, and burrows with Hide and Seek when divers commit.

Abilities and what they actually do

  • Joyful Splash (Normal Attack): Unleash a splash that damages enemies and heals allies. Key numbers: DAMAGE — 70/s; HEALING — 140/s; FIRE RATE — 20 rounds/s; AMMO — 100; PROJECTILE SPEED — 100m/s.
  • It’s Jeff! (Abilities).
  • Aqua Burst (Abilities): Launch a high-speed water sphere that bursts upon impact, dealing damage to enemies within range. Direct hits enemies. Key numbers: DAMAGE — Projectile: 30, Spell Field: 45; FIRE RATE — 1.75 rounds/s; PROJECTILE SPEED — 150m/s.
  • Hide and Seek (Abilities): Key numbers: HEALING — 35/s (self).
  • Healing Bubble (Abilities): Key numbers: HEALING — 30/s.
  • Oblivious Cuteness (Abilities): Reduce damage taken from critical hits.

Constant healing and the 70% headshot discount

Oblivious Cuteness cuts headshot damage by 70%, but Jeff’s head hurtbox is enormous, so the discount is a cushion, not armor. Joyful Splash is a constant stream — 150 healing per second and 50 damage per second at 20 ammo per second — which means your healing scales with how long you safely hold the trigger, not with cooldowns. Aqua Burst is a 70-damage knockback on three charges that refill every 3 seconds; use it to break dives, not to poke. Healing Bubble drops pickups that grant regeneration, move speed, and increased healing received — drop them before fights so allies walk into the buff. Hide and Seek burrows you with move speed and regeneration on an energy bar, but you cannot capture objectives while submerged. It’s Jeff burrows and devours everyone in a large area: allies heal rapidly inside your stomach, and enemies are helpless until you spit them out.

How to play Jeff the Land Shark

  1. Hold Joyful Splash through team fights — 150 healing per second is the highest sustained output of any easy support.
  2. Drop Healing Bubbles before engagements so allies pick up the regeneration and healing-received buff.
  3. Save all three Aqua Burst charges for the diver who reaches your backline; the knockback is your peel.
  4. Burrow with Hide and Seek when a dive commits, then re-emerge behind your Vanguard.
  5. Cast It’s Jeff onto the objective or into a grouped enemy team — never at a single target in the open.
  6. Check for Peni Parker’s nest before ulting; her mines detonate the moment you surface inside it.

Matchups

Jeff out-sustains any team that fights on the objective near him, and his ultimate flips team fights instantly. Spread teams starve his stream, and mobile heroes like Spider-Man and Venom dodge the splash. His ultimate is hard-countered by invulnerability tools like Cloak’s Dark Teleportation and Punisher’s turret, and Magneto and Iron Man can pre-fire their ultimates for the moment you re-emerge.

Strengths (per the wiki):

  • Versatile support with high healing output for both single target and area-of-effect healing while also boasting high mobility; a simple-to-use kit that makes him fit in any team composition.
  • His passive, Oblivious Cuteness, gives him 50% damage reduction against critical hits.
  • His primary fire, Joyful Splash is a continuous long-range stream of water that heals allies and damage enemies.
    • This ability has infinite range and can hit multiple allies that are in its path.
  • His secondary fire, Aqua Burst, is a projectile that deals damage in a radius, being effective to hit multiple enemies clustered together.
    • Direct hits will knock enemies backwards slightly.
  • Healing Bubble is a spherical projectile that travels in an arc, providing healing-over-time to allies in a small area around its radius.
    • This ability can be shot from long distances, and will bounce once when hitting walls or ceilings, allowing Jeff’s healing to reach allies out of his line of sight.
    • The bubbles persist on the map for 180 seconds until picked up, even if Jeff is KO’ed. Up to three bubbles can be placed on the map at once.
  • ** This allows the bubbles to be placed strategically around the map, especially near objectives and choke points, and serve as on-demand ‘healing packs’ for the allied team.
    • This ability also provides a 15% healing bonus from all sources, and 60% increased movement speed for 4 seconds when hitting allies.
  • Hide and Seek is a mobility tool that has Jeff diving underground, with only his fin exposed, vastly decreasing the size of his hurtbox.
    • While submerged, Jeff gains 60% increased movement speed, self healing-over-time, immunity to all forms of crowd control, and can climb walls.
  • ** This extra speed stacks with the bonus from Healing Bubble
  • His Ultimate, It’s Jeff!, allows him to swallow both enemies and allies in a massive radius. While inside Jeff, enemies take damage-over-time while allies heal-over-time.
    • When first activated, Jeff vanishes from the battlefield and the player has 6 seconds to choose where he will attack.
  • ** The area from where Jeff disappears from creates a large pool of healing water that lasts for 8 seconds and affects any allies who step on it.
    • After eating the enemies and/or allies, Jeff is put in his Hide and Seek, and can move around for 6 seconds. After this duration has passed, he’ll automatically spit anyone he swallowed.
  • ** Players can manually spit enemies and allies earlier and separately with different inputs.
    • Overhealing is converted into temporary bonus health for allies eaten.
    • If Jeff falls off a ledge before spitting out, both him and anyone he swallowed will also be taken down.
    • This ability grants Jeff one of the most powerful crowd-controls in the game, and allows him to single-handedly change the course of matches when capturing objectives.
  • When paired with Groot, Jeff gains access to New Friends, allowing him to hop on Groot’s shoulders, granting him 35% damage reduction from all sources.
  • When paired with Venom, Jeff gains access to Guardian of the Deep, where he links himself with nearby allies, granting them healing-over-time for 3 seconds.
    • After the ability’s duration is over, linked allies receive a one-time burst of healing.
    • Overhealing is converted into temporary bonus health, up to 100 extra health.
    • This ability can be activated during Hide and Seek.
  • While Jeff’s passive decreases his damage taken from headshots, he has a very large hurtbox, especially his head, which makes it easy to deal critical hits to him. Additionally, even with the damage reduction he can still be easily taken down by enemies with high burst damage, such as Hawkeye and Hela.
  • Despite his high healing output, Jeff can struggle to heal when the team spreads out.
  • Joyful Splash can be difficult to aim at heroes with high mobility such as Spider-Man and Venom.
  • Joyful Splash’s piercing effect doesn’t apply when damaging enemies.
    • The ability cannot deal critical hits.
  • Aqua Burst cannot deal critical hits, and has limited uses, with only 3 charges that refill over 3 seconds each.
  • Hide and Seek has a limited duration based on its energy cost, meaning Jeff cannot remain submerged indefinitely.
    • In addition, Jeff cannot capture objectives while in Hide and Seek.
  • Jeff can put himself in dangerous situations if he misses his Ultimate, allowing the enemy team to retaliate.
    • Peni Parker can directly counter Jeff’s Ultimate directly if he uses it while inside the area of her Bionic Spider-Nest, which will result in all the nearby Arachno Mines swarming Jeff, likely taking him out.
    • Magneto and Iron Man can preemptively fire their Ultimates after Jeff reemerges.
    • Abilities that provide invulnerability and/or immunity to crowd control can completely negate Jeff’s Ultimate, such as Cloak’s Dark Teleportation, Punisher’s Culling Turret and Final Judgement, Star-Lord’s Stellar Shift, among others.
  • Hopping on Groot’s shoulders can leave Jeff vulnerable, as Groot usually fights in the frontlines. Even with the damage reduction, he can still be focused and taken down easily, or be plucked off Groot with crowd control abilities such as stuns (e.g. Mantis’ Spore Slumber) or knockbacks (e.g. Invisible Woman’s Force Physics).
  • The team-up with Venom doesn’t provide healing to Jeff himself, only to the linked allies.
    • In addition, the healing will be cancelled if allies move 10 meters away from Jeff.

    • In addition, the healing will be cancelled if allies move 10 meters away from Jeff.

Team-ups

  • Guardian of the Deep (with Venom, Season 9.0: The Mystery of Thebes): Shoot out healing tendrils; linked allies receive Continuous Healing, and excess healing is converted into Bonus Health. Enhanced: When teaming up with Venom, symbiote tendrils can also lash out at nearby enemies within range, inflicting continuous damage.
  • Mr. Pool’s Interdimensional Toy Box (with Deadpool, Season 9.0: The Mystery of Thebes): Gain a new ability to spit out a Deadpool Plushie. The plushie continuously Taunts nearby enemies while spraying a healing mist onto surrounding allies. Enhanced: When teaming up with Deadpool, the Deadpool Plushie asserts a much stronger Taunt while concurrently damaging enemies caught in its radius.

Common mistakes

  • Casting It’s Jeff at a single target or in the open, where a whiff hands the enemy a free fight
  • Ulting inside Peni Parker’s Bionic Spider-Nest, where her mines delete you on emergence
  • Trying to capture objectives during Hide and Seek — you cannot hold the point while submerged
  • Standing far from the team, where Joyful Splash and the bubbles reach nobody
  • Treating the 70% headshot reduction as invincibility — focused fire still deletes the big hurtbox
