How to itemise Gloo and, more importantly, why each item earns its slot.

Overview

Why this build works on Gloo

Gloo thrives on sticking to enemies, disrupting enemy formations, and leeching off high-value targets. This build centers on maximizing Gloo's extensive Max HP scaling and innate healing mechanics. Skills like Slam, Slam and Split, Split heal Gloo based on maximum health, while his passive Stick, Stick grants damage reduction that amplifies effective durability. By building items that enhance direct HP pools, passive regeneration, and burst execution, Gloo transforms from a disruptive pest into an unkillable frontliner. The setup solves Gloo's need to survive prolonged engagements while attached to host enemies, guaranteeing he can continuously reset skill cooldowns and drag targets across the battlefield safely without dying.

Item by item

Tough Boots - Dire Hit

Early

Providing essential crowd control reduction, this footwear ensures Gloo reaches enemies to stack Stick, Stick efficiently. The Dire Hit roaming blessing adds potent hybrid damage when target enemies drop below low health thresholds. This synergizes perfectly with Split, Split, allowing Gloo to easily execute low-health host targets after attaching to them or while dragging them across the lane with Pass, Pass during early skirmishes.

In-game passive 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).

Offering physical defense and substantial HP, Cursed Helmet fuels the HP-scaling explosion damage of Slam, Slam. Its burning aura continually ticks against surrounding foes while Gloo splits apart during Split, Split or rides an enemy host. This continuous area damage helps rapidly clear lane minion waves, apply pressure around contested objectives like the Turtle, and keep enemy health chipping away during chaotic teamfights.

In-game passive 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).

Oracle

Core

Oracle is the cornerstone magic defense item for Gloo's kit. Its passive significantly boosts all incoming shield and HP regeneration effects. This amplifies the self-healing from touching Goo in Slam, Slam, the health passive during Split, Split, and the massive burst heal gained upon attaching to a host. With Oracle, Gloo's sustain skyrockets, enabling him to withstand heavy focus fire during intense teamfights.

In-game passive Unique Passive - Bless: Received Shield and HP Regen effects are increased by 30%.

Dominance Ice provides crucial physical defense and attack speed reduction to neutralize physical marksmen and fighters. When Gloo attaches to an enemy hero via Split, Split, this aura automatically sticks to the host and surrounding opponents. It shuts down life steal and health regen reliant enemies while Gloo continuously drags targets into his allies using the Pass, Pass and Slam, Slam combo during skirmishes.

In-game passive Unique Passive - Arctic Cold: Reduces the Attack Speed of nearby enemy heroes to 70% of normal.

Supplying a massive boost to raw HP, Guardian Helmet supercharges all percentage-based healing in Gloo's kit, including the HP recovery on Slam, Slam and Split, Split. Additionally, its out-of-combat regeneration allows Gloo to quickly recover to full health between skirmishes without needing to recall to base, maintaining constant map presence to secure important objectives like the Lord alongside his teammates.

In-game passive Unique Passive - Recovery: Regenerates 2.5% Max HP per second (reduced to 0.5% Max HP per second over 5s after taking damage).

Immortality

Situational

Immortality serves as crucial late-game insurance when diving deep into enemy ranks. If Gloo takes lethal damage before or after attaching to a target with Split, Split, the resurrection gives him a vital second life. The temporary shield provided upon reviving offers enough cushion to immediately recast Slam, Slam to reset cooldowns, heal up, or retreat to safety with his team.

In-game passive 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).

Adapting the build

No build survives every draft. These are the situations where the order above should change.

Against heavy physical damage and fast attack speed enemies

Prioritize finishing Dominance Ice right after Tough Boots - Dire Hit before completing Cursed Helmet. This grants immediate physical durability and attack speed reduction, allowing Gloo to survive early enemy dives and stack Stick, Stick more safely against aggressive physical threats during intense early game lane skirmishes and skirmishes around objectives.

When needing maximum sustain during frequent early teamfights

Rush Oracle immediately after completing your footwear to maximize self-healing early in the match. Amplifying the recovery from Slam, Slam and Split, Split early in the game ensures Gloo can sustain through prolonged team skirmishes around early Turtle fights without having to disengage or recall back to the allied base.

When facing high burst damage teams in the late game

Swap the purchase order of Guardian Helmet and Immortality, acquiring Immortality earlier in the late game phase. This grants Gloo a vital second chance to survive concentrated burst damage combos, ensuring he can complete his Split, Split ultimate attachment without dying during the chaotic initial teamfight engagement.
