This is something I found out the hard (?) way LOL
I have a 2nd account on my shard as a normal player, brought my mage on and decided to check out a dungeon. Went through a moongate and was hidden but had forgotten about it until I was in the dungeon. I was using a GM hiding ball also so it may be the reason I was hidden but don't remember that part to well, just the oOoOoOo was funny
Revealed myself and huge hungry dragon spawned then ate me
This post would also go well under funniest thing we ever saw a player do, I died really well in both 2d as well as 3d according to a friend LOL
