Well I would have started a new thread about this because I searched the site for a post already made and nothing came up but as you see I'm in leecher status so...
To do this you need to be a priest
I was in AB the other day and I was trying to sneak up into BS and cap the flag but I saw a druid in cat form beside the flag... because i was sneaking in from the stables side of BS he couldn't see me because of the hill blocking his view. Since I saw him i figured there where a few other stealthed enemys around which was true because later i got raped by 3 rogues and that druid.... But anyways I used mind vision on the druid to try and see some stealthed rogues around him. I didn't see any rogues but what happened was cooler the druid stealthed up and my mind vision didn't break and when i looked up over the hill i could see a stealthed druid walking around

so i went up and casted a swpain on him and got destroyed by the rogues....
So.. I have concluded that if your in range of a druid or rogue that is out of stealth and is about to enter it if you mind vision him as he enters you can see where he is when you break mind vision...
