User blog comment:Willbachbakal/(Champion Rework) Kalista, the Spear of Vengeance/@comment-1920550-20150807213348

An interesting thing to note it the application of several mechanics of Kalista's kit that have been converted into item core points by Riot. (Tether, Martial Poise and Rend mechanics)

The reworked Zeke's is a major example of this aswell as several Black Market Brawlers items such as Martyr's Gambit, Pox Arcana and Flesheater. Mirage Blade could also be considered to a lesser degree. I find Kalista to have been pretty much a guinea pig to determine what kind of new mechanics Riot could introduce to a sucessful degree in other forms and classes.
