Ghostcrawlers

Stats

Values as the League of Legends Wiki's item data lists them, for every mode; the data doesn't state their units.

Effects

• Wall Walk (unique): Become ghostly for 6 seconds, ignoring terrain collision until you basic attack or cast an ability. While inside terrain, gain 300 bonus movement speed.³

• Ghostcrawlers are recommended on Urgot with Hexbolt and Runecarver; Urgot can attack while moving and attack through walls with the boots.⁴
• Ghostcrawler boots are especially useful for juggernauts in the longer early rounds, where their movement speed helps low-mobility champions kite or avoid being kited, reach flowers, and get to resurrection circles.⁵

• Ghostcrawlers can still let champions pass through terrain until they attack or cast a spell.⁶
• When Pyke casts Bone Skewer while Wall Walk is active, the ability is cancelled immediately and goes on cooldown, although its cast sound still plays.⁷ Patch unknown
• Pyke's E can stop during its dash when Ghostcrawlers are used.⁸
• Urgot can basic attack through walls with Ghostcrawlers.⁴
• Tenacity usually stacks multiplicatively.⁹

• Zoe's Spell Thief can drop Ghostcrawlers as a Spell Shard.¹⁰ Patch unknown
