Sticky control tank who wears enemies down with slows and damage transfer
TankEXP LaneRoamDeals magic
Gloo is a durable magic-damage tank who wears enemies down rather than bursting them. Stick, Stick stacks a slow and a damage-reduction debuff on anyone hit by his skills, Slam, Slam and Spread, Spread chain immobilize effects, and Grab, Grab attaches to a fully-stacked target to transfer 80% of the damage Gloo receives back onto them.

Strengths
Stick, Stick's damage reduction stacks up to 20% just from repeatedly hitting a target with skills
Slam, Slam heals Gloo and instantly resets its own cooldown when he touches the leftover Goo
Grab, Grab transfers 80% of the damage Gloo takes onto the attached target, turning him into a damage sponge
Spread, Spread's merge mechanic lets him relocate mid-fight while dragging enemies along the way
Weaknesses
Grab, Grab only unlocks once a target already has full Sticky stacks, so it can't open an engage
Low burst damage overall — he wins fights through attrition and control, not raw kill pressure
Spread, Spread's split state leaves him more spread out and easier to isolate if focused mid-animation
No hard displacement like a knockup or suppression, only slows and immobilize that tenacity items chip away at
Skills
Max Slam, Slam first for the reset-heal loop, then Spread, Spread for AoE control and merge mobility, taking the ultimate at 4, 8 and 12.
Passive
Stick, Stick
SlowBuff
Enemies gain a stack of Sticky each time they're hit by Gloo's skills, decreasing their Movement Speed by 4% for 6 seconds. Stacks up to 5. Each stack of Sticky on an enemy reduces their damage dealt to Gloo by 4%.

Skill 1
Slam, Slam
AOECC
Gloo reaches out and slams the ground, dealing 80 (+80% Total Magic Power) Magic Damage to the enemy. At the final, a Goo is left behind that explodes after 3 seconds to deal 300–450 (+12% Extra HP) Magic Damage to nearby enemies and immobilize them for 1 second. If Gloo touches the Goo, it will explode immediately, reset the skill's cooldown, and heal Gloo for 2.5%-5% of Max HP if the explosion hits an enemy (doubled if hits an enemy hero).

CCAOE
Gloo splits into Goos, dealing 100–200 (+80% Total Magic Power) Magic Damage to enemies in a fan-shaped area and immobilizing them for 0.5 seconds. While split, Gloo gains 10% Movement Speed and deals 80 (+15% Total Magic Power) Magic Damage every 0.25 seconds to enemies it touches, lasting 4 seconds. If this skill hits a Goo, Gloo will charge over to merge with it, dragging enemies in its path in the same direction for a distance.

One is all. (All is one.)Unlocked when any enemy hero has full Sticky stacks. Gloo attaches itself to the target enemy hero for up to 9 seconds, recovering 25%-30% of its Max HP. For the duration, its Basic Attacks are converted to deal 30–90 (+50% Total Magic Power) (+6% Extra HP) Magic Damage, and it transfers 80% of the damage it receives (excluding damage from turrets) to its host.

Gloo builds
Core items in buy order, with the emblem, talents and battle spell that go with them.
Sticky Control Tank
7,050g total
Default pick as the team's primary frontline and control hero.
The 'Flicker combo' — blinking in right as a hook or stun lands, or blinking out the instant an enemy ultimate is cast — is the single most common high-elo outplay moment in the game.
Swap in when needed
Athena's Shield — Against a burst magic diver he has to engage into first.
Antique Cuirass — Against physical skill-combo fighters punishing his slow engage.
Immortality — Insurance when attaching Grab, Grab to a priority target.
Gloo Sticky Control Tank build: Tough Boots, then Dominance Ice, then Brute Force Breastplate, then Queen's Wings.
Regen Sustain
7,330g total
When Gloo needs to hold a lane or extended fight rather than pick fights.
Because the shield is flat and doesn't scale with items, its relative value drops in the late game — it's strongest as a laning-phase and early-mid-game defensive tool.
Swap in when needed
Radiant Armor — Against sustained magic damage in extended fights.
Land Slam, Slam and touch the resulting Goo yourself to instantly heal and refresh the skill for a second cast
2
Stack Sticky on the enemy carry specifically — it directly reduces the damage they deal back to you
3
Only cast Grab, Grab once a target already shows full Sticky stacks; it's a finisher, not an opener
4
Use Spread, Spread to merge back through a chokepoint, dragging chasing enemies with you
Gloo — common questions
Is Gloo good for beginners?
Gloo is beginner-friendly overall — his zones are forgiving AoE skills, though getting full value from the Goo merge and timing Grab, Grab correctly takes a bit more practice.
What is the best build for Gloo?
Tough Boots into Dominance Ice, Brute Force Breastplate and Queen's Wings is the standard sticky-control build, since all of his skill damage scales off Magic Power.
Which heroes counter Gloo?
Fanny, Diggie and Ling are the hardest counters because they bypass his ground-based zones and slows outright, while Faramis, Alice, Ruby, Moskov, Fredrinn, Natan and Wanwan all deny or outlast his control in softer ways.
What does Gloo's ultimate do?
Grab, Grab attaches Gloo to an enemy hero who already has full Sticky stacks, healing him and converting his basic attacks to magic damage while transferring 80% of the damage Gloo takes onto that host for up to 9 seconds.
