Wall-Nine is an extremely common technique, involving Berserker's Nine Lives. When used correctly, it is possible to cast Nine Lives almost instantaneously. It is also fairly simple to learn, making it one of the easiest moves to teach.
Step 1: Click on Nine Lives
Step 2: Aim Nine Lives so that an unpathable area is in its path
Step 3: Click on the area
Step 4: Success!
If you aim out of Nine Lives' casting range, you will not cast Nine Lives successfully and instead Berserker will walk towards the location before going into Nine Lives.
Note that Trees are not considered unpathable, and you will simply phase through them if you attempt to wall-nine on them. This includes lamp posts.
[edit] Advanced TacticsWhile Wall-Nine is very fast, the enemy might still react fast enough to escape. As such, you can combine a short stunning ability to incapacitate the enemy and allow you to nine on your target successfully. Recommended items for such use are C Scrolls and S Scrolls.
The further away you aim with Nine Lives, the faster berserker moves. Therefore, to get the maximum possible speed possible, aim at the maximum range of Nine Lives, 700.
