Not sure if this s a bug or something they changed. Had my lane partner and the person i used my oath-sworn ability on leave 5 minutes into the game and after was unable to select another person to use oath-sworn on effectively taking away a huge chunk of damage and my ult. I bought a new spear but when i tried to bind i would get the bell toll then nothing would happen.

You have up to the 3:00 mark to re-bind with Kalista.
Nicorus 2 votesIn the scenario where a champion afks, why not allow Kalista to rebind?
Matthias91191 votesCould be abusable in organized play. Bind to player A for laning phase, have A DC for a minute so you can swap it to B in the mid/late-game...

TIL!
Didn't know you could rebind at all. I was wondering why you could even buy a 2nd 
. Other than amusement of spamming it on people in custom games, lol
Maybe after the 3min mark remove it from shop? Is that possible?
Omnipotent One1 votesThanks a lot, that's good to know although it is a little frustrating to have the entire champion become useless if Kalista's Oath-Sworn AFK's or D/C's is there a possible solution in the works about this? I've found on rare occasions it is possible to win a 4v5 but with Kalista so reliant on her Oath-Sworn ally if they disapear your essentially losing two members of your team and makes it nearly impossible to attempt a 4v5 win if that person is the one you loose from AFK or D/C.
Riotmoonstones1 votesThe way the skill is currently functioning is working as intended, and to the best of my knowledge, we don't have plans to change the functionality.
USG Morta2 votesi think you can only rebind if its before a certain time. maybe 2 min? or 3? idk what it is exactly.
