If time ticks down or everyone readies up in a tournament and it says “The match is about to start” or w/e… If you’re fighting before the game starts and you hit vengeance right before it teleports you into your base… you will still have vengeance during the 10 second prep period and will exit the gate with it up.
tl:dr Don’t use vengeance when it says “the match is about to start” in tpvp. You will die right after the game starts.
