I am quite new to caravan escorts. After 3 runs I haven't realized how it could be possible to end the caravan in less than 8 mins for achievements.

I mean, the party I did the caravan with nearly oneshotted all of the mobs, but still we just did it in less than 12 mins.... I really do not see margins to get 4 mins faster...

Is there some way to make the caravan move faster, so that the mobs spawn earlier? And if not, how to do it faster?

Thank you very much?
