Anyone have a quick way to raise my rep wit the legion? I've already recieved his mark, but im too vilifed to go speak with him. If i try sneaking into the fort i can get into his tent, but then his guards murder me. I've already completed majority of the quests for the NCR.

You see, there is positive rep and negative rep, and IIRC Legion don't tolerate any negative rep unless you jeep the mark.

If you are aiming for the player house, than it is easier: just find ways to get NCR dogtags and give them to Aurelia at Cottonwood Cove.

On PC? If so, you can use console commands.

the problem is that i can't talk to aurelias without him attacking me first

Are you on PC or console? If it's PC we can fix this in all of two seconds.

unfortunatey no, im on the xbox

That's your anwser to everything
