Gloo's skills apply a stack of Sticky to enemies on hit, decreasing their Movement Speed by 4% for 6s (up to 5 stacks).
Each Sticky stack on an attacker reduces their damage dealt to Gloo by 3%.
Gameplay guide
Gloo is an EXP-lane or roam tank who applies five Sticky stacks to slow enemies and reduce their damage to him. He repeatedly detonates Goo for Max-HP healing and cooldown resets, drags enemies through a fan-shaped spread, then attaches to a fully stacked hero and transfers 80% of incoming non-turret damage to that host.
Cast Slam ahead, walk over the Goo to trigger its explosion and reset, then repeat while applying Sticky and healing. Use Spread through the Goo to charge and drag an enemy only when the landing remains safe.
Stack a priority hero at objective fights, unlock Grab, and attach before enemies burst Gloo down. While attached, place Slam at the host's path, use Spread to control movement, and basic attack for Max-HP-scaled magic damage.
Choose a carry rather than attaching to the first available tank. Coordinate allied focus, avoid turret zones, and exploit the five-second ultimate cooldown if the host dies while attached to threaten another target.
Before attaching, check the target's retreat direction; following them under a turret can turn the ultimate into a trap.
Spread Sticky marks with repeated area contact before attaching, making the host easier to slow and sustain against.
Use Split, Split on a durable or isolated enemy only when allies can hit that host safely; attaching to a retreating carry can drag Gloo away from support.

Charge and drag targetTouch or detonate Goo

Spread immobilizes and charges through the Goo while dragging targets across skill damage, accelerating five Sticky stacks and the attachment unlock.



Attached skills remain available; Goo and Spread control the host's route while damage directed at Gloo is transferred back to it.
