Assessment
Gloo stands out as a highly durable hero, boasting a perfect 100 in durability, allowing him to absorb immense amounts of damage and remain on the front lines for extended periods. This exceptional tankiness makes him a reliable protector for his team, capable of initiating engagements and peeling for carries. Furthermore, his magical offense is surprisingly potent for a Tank, rated at 100. This means Gloo can deal significant magic damage, especially during his ultimate, providing a threat beyond just crowd control and making him less reliant on his team for all damage output.
However, Gloo's effectiveness comes with a notable difficulty rating of 70. His kit requires precise execution, especially with the placement of his Goo and the timing of his ultimate, making him challenging for newer players to master. His physical offense, rated at a low 30, means he contributes very little with basic attacks outside of his ultimate form, relying almost entirely on his magical abilities for damage. Additionally, while his ultimate is incredibly powerful for disruption and damage transfer, if it is on cooldown, Gloo loses a significant portion of his engagement potential and sustain, making him more vulnerable during these windows.
Kit

Passive
Enemies gain a stack of Sticky each time they're hit by Gloo's skills, decreasing their Movement Speed by 6% for 6s. Stacks up to 5.
Each stack of Sticky on an enemy reduces their damage dealt to Gloo by 6%.

Skill 1
Gloo reaches out and slams the ground, dealing 80 (+80% Total Magic Power) Magic Damage to the enemy.
At the final location, a Goo is left behind that explodes after 3s to deal 200+8% Total HP Magic Damage to nearby enemies and immobilize them for 1s. If Gloo touches the Goo, it will explode immediately, reset the skill's CD, and heal Gloo for 3% of Max HP.

Skill 2
Gloo stretches forth to deal 100 (+50% Total Magic Power) Magic Damage to enemies in its path, immobilizing them for 0.5s.
If this skill hits a Goo, Gloo will charge over to it, dragging enemies in its path in the same direction for a distance.

Ultimate
Gloo splits into Goos for 10s, during which it gains 35% extra Movement Speed, recovers 1.5% Max HP per second, and deals 120 (+25% Total Magic Power) Magic Damage every 0.25s to enemies it comes into contact with.
Grab, Grab: Gloo attaches itself to the target enemy hero with max Sticky stacks for up to 9s, recovering 25% Max HP. For the duration, Gloo transfers 80% of the damage he receives (calculated before damage reduction; excluding damage from turrets) to its host, and its Basic Attacks deal 120 (+50% Total Magic Power) Magic Damage.
Go, Go: Gloo leaves its host early.
Cooldown is lowered to 5s if the host dies while Gloo is still attached to it.
Gloo's unique abilities revolve around his 'Sticky' mechanic and the 'Goo' blobs he leaves behind, allowing for exceptional crowd control and disruption.
His passive, Stick, Stick, is fundamental to his playstyle. Each time Gloo hits an enemy with a skill, they gain a stack of Sticky, reducing their Movement Speed by 6% for 6s, stacking up to 5 times. Crucially, each stack also reduces the damage the affected enemy deals to Gloo by 6%. This passive is vital for his survivability, as it directly mitigates incoming damage from key targets, making him even tankier against focused fire. It also provides consistent slow, enabling easier follow-up from allies.
Slam, Slam is Gloo's first skill. He slams the ground, dealing 80 flat + 80% scaling (Total Magic Power, Magic) to enemies. At the impact point, a Goo is left behind that explodes after 3s, dealing 200 flat + 8% scaling (Max HP, Magic) and immobilizing nearby enemies for 1s. If Gloo touches this Goo, it explodes immediately, resetting the skill's cooldown and healing Gloo for 3% of his Max HP. This skill is Gloo's primary source of wave clear, poke, and short-range crowd control. The magic power scaling means early magic damage items can boost its initial hit, while the max HP scaling on the explosion makes it scale well into the late game with defensive tank items. Using it to immediately detonate the Goo for a quick cooldown reset and heal is key for sustained fighting and mobility.
His second skill, Pass, Pass, allows Gloo to stretch forth, dealing 100 flat + 50% scaling (Total Magic Power, Magic) to enemies in its path and immobilizing them for 0.5s. If this skill hits a Goo, Gloo will charge to it, dragging enemies in his path. This skill is crucial for Gloo's mobility, engagement, and secondary crowd control. The magic power scaling contributes to his damage, but its main purpose is the dash and enemy displacement. Combining it with Slam, Slam allows Gloo to quickly close gaps, reposition, or pull enemies into favorable positions for his team.
Gloo's ultimate, Split, Split, transforms him into multiple Goos for 10s, granting 35% extra Movement Speed and recovering 1.5% Max HP per second. During this state, he deals 120 flat + 25% scaling (Total Magic Power, Magic) every 0.25s to enemies he touches. The most impactful part is Grab, Grab: Gloo can attach to an enemy hero with maximum Sticky stacks for up to 9s, recovering 25% Max HP. While attached, he transfers 80% of the damage he receives (before damage reduction) to his host, and his Basic Attacks deal 120 flat + 50% scaling (Total Magic Power, Magic). He can detach early with Go, Go. This ultimate is Gloo's signature ability, allowing him to dive into enemy backlines, disrupt their formation, and turn a high-priority target into a damage sponge. The healing and damage transfer make him incredibly resilient, while the basic attack scaling provides significant burst potential against the attached target. The cooldown is significantly reduced if the host dies while Gloo is attached, encouraging aggressive plays.
Items
Unique Passive - Burning Soul: Deals Magic Damage equal to 0.6% of the hero's Max HP per second to nearby enemies. This damage is increased by 140% to 350% against creeps and minions (scales with level).
Unique Passive - Passive - Dire Hit: The next attack against enemy heroes below 35% HP deals 7-18% of their Max HP as extra Hybrid Damage (half Magic and half Physical).
Unique Passive - Bless: Received Shield and HP Regen effects are increased by 30%.
Unique Passive - Immortal: Revives 2.5s after death, gaining 16% Max HP and a 220-1200 shield (scales with level) that lasts 3s (210s cooldown).
Unique Passive - Arctic Cold: Reduces the Attack Speed of nearby enemy heroes to 70% of normal.
Unique Passive - Recovery: Regenerates 2.5% Max HP per second (reduced to 0.5% Max HP per second over 5s after taking damage).
Gloo's recommended build focuses on maximizing his durability, magical damage output, and sustain to allow him to effectively fulfill his role as a disruptive Tank.
Cursed Helmet is an excellent early item for Gloo. Its Unique Passive - Burning Soul deals continuous Magic Damage equal to 0.6% of Gloo's Max HP per second to nearby enemies. This synergizes perfectly with Gloo's high base HP and his desire to stay close to enemies, providing constant damage, especially useful for clearing minion waves and applying pressure in lane. The damage increase against creeps and minions also helps him farm efficiently.
Tough Boots - Dire Hit provides crucial magic defense and crowd control reduction, which is vital for a frontline Tank. The Dire Hit passive is particularly strong for Gloo, as it allows him to execute low-health enemies. The next attack against enemy heroes below 35% HP deals 7-18% of their Max HP as extra Hybrid Damage. This can be triggered by his skills or basic attacks while in ultimate form, helping secure kills on squishy targets he manages to attach to.
Oracle significantly boosts Gloo's sustain. Its Unique Passive - Bless increases received Shield and HP Regen effects by 30%. This directly amplifies the healing from his Skill 1 (when touching a Goo) and his ultimate's passive HP recovery, making him much harder to take down and allowing him to remain in fights longer.
Immortality is a core defensive item for any Tank, providing a second chance in crucial team fights. Its Unique Passive - Immortal revives Gloo 2.5s after death, granting 16% Max HP and a shield. This passive is invaluable for extending his presence in prolonged engagements, allowing him to re-engage or absorb more damage after being focused down.
Dominance Ice is a powerful counter-item against attack speed reliant enemies. Its Unique Passive - Arctic Cold reduces the Attack Speed of nearby enemy heroes to 70% of normal. This significantly diminishes the damage output of enemy Marksmen and Fighters, making Gloo and his team much more resilient against burst physical damage. It also provides mana and physical defense, both beneficial stats for Gloo.
Finally, Guardian Helmet further enhances Gloo's incredible HP regeneration. Its Unique Passive - Recovery regenerates 2.5% Max HP per second, making him incredibly difficult to poke down and allowing him to quickly recover health between engagements without needing to recall to base. This item ensures Gloo maintains high HP throughout the game, maximizing his effectiveness as a frontline tank.

Coaching
Gloo's playstyle revolves around constant disruption, damage mitigation, and opportunistic engagements. As a highly durable Tank with good magical offense, your primary goal is to control the battlefield and protect your damage dealers.
In the early game, focus on utilizing your Skill 1, Slam, Slam, to clear minion waves and poke enemies. Practice placing the Goo blob strategically so you can quickly dash to it with Skill 2, Pass, Pass, to reset its cooldown, heal, and potentially immobilize enemies. This combination is essential for sustained lane presence and surprise engagements. Consistently applying Sticky stacks with your skills is crucial, as the damage reduction from your passive, Stick, Stick, significantly enhances your survivability.
During teamfights, Gloo excels at initiating and diving the enemy backline. Look for opportunities to hit multiple enemies with your Skill 1 to apply Sticky stacks. Once a squishy enemy hero has maximum stacks, activate your ultimate, Split, Split, and then use Grab, Grab to attach to them. This turns the enemy into a mobile bomb, forcing their team to either damage their own ally or suffer Gloo's damage transfer. While attached, continue to use your basic attacks and Skill 1 for additional damage and to maintain pressure. Your high durability allows you to withstand focus fire, especially with the damage transfer from your ultimate.
Positioning is key for Gloo. You want to be at the forefront of engagements, absorbing damage and setting up plays. However, be mindful of your ultimate's cooldown. Without Split, Split, Gloo loses a significant portion of his threat and survivability. Use the mobility from your Skill 1 and 2 combo to reposition, escape, or chase down fleeing enemies. Always aim to detonate your Goo for the cooldown reset and heal, as this allows for more frequent skill usage and greater sustain.

In practice
Imagine a scenario where your team is grouped, and the enemy carries are slightly out of position. As Gloo, your goal is to initiate and disrupt their backline. First, cast Slam, Slam towards the enemy Marksman or Mage, aiming to hit them and leave a Goo blob at their feet. As the Goo is about to detonate, use Pass, Pass, aiming it at the Goo. This will cause Gloo to charge towards the Goo, immediately detonating it for the immobilize and healing you, while also dragging any enemies in your path. This combo not only provides crowd control but also positions you deep within the enemy formation.
Once you are amidst the enemy backline, and your primary target has accumulated sufficient Sticky stacks from your initial skills, activate your ultimate, Split, Split. Immediately use Grab, Grab to attach to the most dangerous enemy carry. This forces them out of position and transfers 80% of the damage you take to them. Your team can then focus fire on the attached target or the remaining enemies, while you soak damage and deal continuous magical damage from your ultimate and basic attacks.
