Elise from Teamfight Tactics Set #7.5

Ability

Spider Form

Elise transforms into Spider Form for the rest of combat, reducing her Attack Range to 1 and replacing her ability with Venomous Bite, which she immediately casts.

Venomous Bite: Elise's next attack deals @ModifiedDamage@ bonus magic damage. If this kills her target she ascends, becoming untargetable before dropping near the lowest Health enemy and immediately casting Venomous Bite again.
