Ice Hunter's Arcane Boots
Early
Ice Hunter's Arcane Boots provide Harley with essential Jungling efficiency and early movement speed to rotate between lanes. The extra magic penetration directly amplifies the damage of Poker Trick during early ganks. Additionally, the Retribution true damage passive helps Harley secure jungle creeps, Turtles, and early objectives smoothly, allowing him to quickly gain the level advantage needed to unlock Deadly Magic and begin executing squishy targets across the map.
In-game passive Unique Passive - Hunter: After dealing damage to a Creep, deal 25<2|lv 3> + True Damage to the target over 3s (damage is increased by 100% for non-Marksmen heroes).
Genius Wand is Harley's ultimate early core item because its Magic Defense reduction stacks alongside his passive Magic Master. When Harley blinks in with Space Escape and rapidly strikes enemies using Poker Trick, Genius Wand shreds enemy Magic Defense to near zero. This drastically increases the damage taken during his ultimate Deadly Magic, ensuring the final explosion deals maximum lethal burst damage to squishy enemy heroes.
In-game passive Unique Passive - Magic: Dealing Magic Damage to enemy heroes will reduce their Magic Defense by 3-7 (scales with level) for 2s. Stacks up to 3 times.
Feather of Heaven enhances Harley's unique basic attack mechanics dictated by Magic Master. Since his passive converts basic attacks into scaling magic damage and grants stacking attack speed, Feather of Heaven adds extra magic damage to every basic attack. During the four second window of Deadly Magic, Harley can weave basic attacks alongside Poker Trick, ensuring maximum damage is absorbed into the ring before it explodes.
In-game passive Unique Passive - Affliction: Basic Attacks deal extra Magic Damage equal to 50 plus 30% of the hero's Magic Power.
Starlium Scythe seamlessly fits Harley's combo flow. After casting Space Escape or Deadly Magic, Harley's next basic attack deals additional True Damage and grants a brief movement speed boost. Because true damage bypasses defenses, this extra burst contributes significantly to the total damage absorbed by Deadly Magic ring. The added movement speed also makes it easier to position Poker Trick waves or re-adjust before returning to his hat.
In-game passive Unique Passive - Crisis: Within 3s after casting a skill, the caster's next Basic Attack will deal additional True Damage equal to 100 plus 100% Magic Power and briefly grant 10% Movement Speed. This effect has a 1.5s cooldown.
Holy Crystal provides a massive percentage spike to Harley's total Magic Power in the mid-to-late game. Since both Poker Trick and Deadly Magic scale heavily with Magic Power, this item exponentially elevates his overall burst damage. With Holy Crystal completed, a single combination of Deadly Magic and Poker Trick becomes capable of instantly eliminating high-priority enemy targets before they can react or receive healing.
In-game passive Unique Passive - Mystery: Gains 21%-35% extra Magic Power (scales with level).
Divine Glaive is Harley's primary response to enemies building high Magic Defense items in the late game. Its passive Spellbreaker grants scaling Magic Penetration based on the target's Magic Defense. When combined with the flat defense shred from Magic Master and Genius Wand, Divine Glaive ensures Harley can still melt tanky targets and frontliners with Deadly Magic even when they attempt to counter his magic damage.
In-game passive Unique Passive - Spellbreaker: When attacking an enemy, gains 0.1% extra Magic Penetration for each point of the enemy's Magic Defense, capped at 20%.
