If i am in a game that is currently spawning herald of terror, if someone else joins and i leave will they still spawn herald lvl 5s?

or does it depend on the person who killed them?

The states are game-wide. Herald tier goes up for the whole game, regardless of who, ire stays active even if you leave game and rejoin it. Ire triggers for everyone at the same time, so people can hijack it by teleporting around really fast.

gotcha thanks, reason asking is becuase ive been doing herald runs all day in 1 game and am about to leave. there are still some un touched areas and was gonna see if anyone wanted the game and pass before i left
