Passive: Martial Poise Rather than cancelling the basic attack animation, a move order hops Kalista in the direction of the click after she completes her attack. Kalista leaps farther when moving away from her target.

Q: Pierce Kalista hurls a spear, damaging the first enemy struck and adding a stack of Rend. Pierce also procs Martial Poise.

W: Sentinel Passive: Soul-Marked—When Kalista and her bound ally attack a minion, monster or enemy champion at the same time, they deal bonus magic damage. Active: Kalista commands a sentinel to keep watch over an area. The sentinel patrols back and forth in a line a few times. Vulnerable to attacks from behind, sentinels see in a cone in front of them and scream if they spot an enemy champion.

E: Rend Kalista’s basic attacks and the spear from Pierce lodge in their target for a short time. Rend causes her to rip the spears from her enemies, slowing them and dealing increased damage for each spear rent from the target. Rend’s cooldown resets if it secures a kill on an enemy unit. The spears stack infinitely, only disappearing if Kalista fails to keep up her assault.

R: Fate's Call Kalista repositions her bound ally next to her, making them untargetable and disabling their spells. During Fate’s Call, Kalista’s Soul-Bound gains a new ability, which allows the Soul-Bound to dash in a target direction, knocking up enemies they strike.

She seems like a pretty cool champ, a lot of utility in her kit could be a problem. Thoughts Comments?
