And tell your friend Mra to stop being such a coward. He's a hacker, and still does Alt+F4 against me.

*ropleplaying intensifies* lol

I made myself invisible to look out for your friend. Don't try to turn things against me. I invaded your friend normally in Undead Parish, and for any reason he just left the entire area and went to upper Undead Burg. After a few minutes looking for him, I started flying to search for him. But of course: I should not be surprised of him hacking, when you're also a hacker and you only focus in backstab people.

how do you do to make yourself invisible?, that was a suprise

Tell your friend Azelard to stop hacking in Dark Souls 1.
