Kalista's black spear

{quoted}

Yes, if you rebuy the Black Spear (0 Gold) you can rebind to someone else as long as the game is under 3 minutes. After that, you're stuck with your Oathsworn.

this, it's basically there in case you accidentally clicked someone wrong or realized you want to do something else when the game is starting. The time limit is obviously there to prevent people from switching later on and like, go from a squishy oathsworn to the much beefier tank later on in the game oathsworn to throw into the enemy team.

that would be absurd levels of BS
