Just something I noticed that can be incredibly *******ish but pretty entertaining while you wait for a boat or zeppelin. It involves the basic DK cc and can cause people to miss their ride.
1. Obviously, go to a dock or tower(?), depending on which faction you play.
2. After the boat comes, drop the /duel command on a nearby player thats waiting with you.
3. If it's a lowbie, /dance or toy around with him. If not, try to prolong the duel without burning your death grip or chains of ice.
4. When the boat begins to move, death grip your victim (if they are far) and chains of ice them.
5. Run onto the boat and wave goodbye.
The further away you can pull them, the better, as long as you can get onto the boat yourself (if you desire to that is).
Hope some of you have a little fun with this. Enjoy!
