nothing can attack you and you cannot attack anything. Mobs can't even 'see' you because technically you're not there.

If you see anyone taking close-up pictures of huge bosses, this is how it's done.
On that note, there was someone a while ago on belenus called TheRapist who used this glitch to hassle people in the arena.

Once you log out, the glitch is gone. Here is how (DO NOT USE IT TO YOUR ADVANTAGE ): First you kill yourself, you do not use a idol or go to leystone at all instead log out, wait 30 minutes-1 hour then log in, poof your invincible (I did it this way).
NOTE: Not a hack but a exploit.

Can you still unlock leystones with this method?

Ok, I tested on my level 22 alt, I unlocked leystones with it....
