I have tried this, You cant use the room jumping feature in any PVP map, when you do it doesnt allow you to attack players, NPCs or move between rooms, my best guess is that it uses a packet to log your movement,
example: you cant go through this door without this packet if you do, Null character
so your best bet is just using the Le bot one which just stands in the room hoping for it to win.
However if you would like a fast way that you need to do manually you can join chaos brawl with 2 accounts, get your side to 1000 points once it reaches 1000 points keep killing your alt account, each kill will get you 8 trophies, you will have 500 in around 10-20 mins, good luck.
