Below are the build(s) we are using with Lucario in Pokemon Unite. Please note that for the items below we upgraded them to level 20 to increase their effectiveness!
The Blue Streak
Battle Item: Goal-Getter / X Attack / Eject Button
Held Item 1: Muscle Band
Held Item 2: Float Stone
Held Item 3: Scope Lens
Move 1: Extreme Speed
Move 2: Bone Rush
For this build, we wanted to have Lucario move around quickly while dealing solid damage to keep the enemy at bay. This led us to choose Extreme Speed and Bone Rush for its moves. Extreme Speed gives you extra mobility to engage or chase down enemies. When used in close vicinity of an opponent, the cooldown gets reset allowing for multiple uses. It even restores a little HP to keep you fighting longer! Bone Rush was chosen for its wide attack radius with the additional effect of throwing the bone. If you activate the skill a second time, Lucario rushes to the bone, dealing damage to anything in its way. This move also gives it a little more mobility. The held items that go along with this build are Muscle Band, Float Stone and Scope Lens. The Muscle Band is used to increase Lucario’s damage and attack speed paired with the Scope Lens to increase the critical chance and damage. This combination increases the damage of its skills with a higher chance to land a critical hit. Then you have the Float Stone to increase how fast Lucario can get around while also boosting its attack some more. When it comes to battle items, there are a couple of options. Goal-Getter is useful to help dump your points before an enemy shows up. You can substitute that for an X Attack to increase Lucario’s damage during a bigger fight or an Eject Button to help with a strategic retreat. This build is better utilized when playing the upper or bottom lane.
