Shaco

Few puppets built to console a lonely prince end up synonymous with murder, yet Shaco pulled off exactly that transformation.

Long ago he was crafted as a plaything for a prince with no companions, and by all accounts he filled that role admirably, showing whatever limited kindness a marionette is capable of. Then came the death of the child he was made for, followed by dark magic that seized him once that bond was severed. The gentle toy turned into a jester who revels in slaughter and chaos, regarding each kill as the punchline to a joke only he finds amusing.

Shaco is an Assassin who draws on Mana and most often roams the mid lane. He still plays with toys, though none that anyone would hand to a child. His passive, Backstab, boosts his basic attacks and Two-Shiv Poison damage when he hits from behind. Deceive makes him invisible and teleports him to a location of his choosing; it is strongest when aimed at terrain, because it lets him slip out of a fight cleanly instead of merely sidestepping. His next attack from that invisibility carries bonus damage and is guaranteed to crit if it connects from behind, which is one more reason critical damage items suit him. Jack In The Box leaves a concealed animated box that terrifies and assaults any foe who sets it off, and its on-hit effects grow with the equipment Shaco is carrying. Two-Shiv Poison makes his throwing knives poison on contact, slowing the target, and the thrown version hits harder when that poison is already applied. His ultimate, Hallucinate, summons an illusion of Shaco that attacks nearby enemies and benefits from the same on-hit items, then bursts into three more Jack-in-the-Boxes when it dies. Because he has to commit Deceive to open a fight, he has no fast way to reuse it for an escape, and that is precisely the window his opponents look for to fight back.

Shaco owes allegiance to no nation; his only master is Runeterra, and he drifts toward whichever shadowy corner offers cover. Fellow wanderers of that same untamed ground, such as Evelynn and Fiddlesticks, likewise prefer to lurk just beyond sight.
