If Kalista enters a movement command while winding her basic attack or Pierce, she will drive through that direction when she launches her attack, dashing a short distance. The distance traveled scales with bonus movement speed.
Additionally, Kalista begins the game with a unique item, The Black Spear.
The Black Spear - Active: Kalista offers a pact to an allied champion. Should they agree, the item is consumed and binds them together, turning the target into an Oathsworn ally for the remainder of the game. Kalista requires an Oathsworn ally to utilize Sentinel's Soul-Marked and Fate's Call.
