Speed running ? in dungeons, now why would a person do that ? The answer is that some dungeons have a very short timer and so the skill is in moving through the dungeon guickly.

Dungeon Fail

Now this first video is auto run, its to give a idea about the dungeon which is dungeon 8 insane mode... and its one of the earliest dungeons that players will encounter, dungeon 8 that is, insane mode is the 3rd difficulty setting.

Now in that dungeon, in insane mode, the timer is short, the NPCS hard to kill and they respawn behind you after you kill them so if you mess around, you will very quickly run out of time..... as you will notice, not only did I fail to clear the dungeon in the elite boss kill time, I failed to even get to the boss in time before the dungeon time ran out.

Dungeon success

Now in this video I cleared it with seconds to spare.. which gives you a idea on how hard it can be to run solo..... running it in a team is a lot easier.....

Clearing it was simple because I used a few simple tricks

1/ do not stand around, do not waste time picking up items, you can do that after you kill the elite boss

2/ keep moving forward, do not bother taking out all of the NPCS, you are wasting your time.....

3/ if you keep triggering your left mouse skill and slowing yourself down, then remove the left mouse click so its movement only..... I did not do that because I made sure I clicking between the npcs so I could keep moving forward. But do not be fooled, I failed that dungeon 16 times before I cleared it within the time limit, its one of the hardest low level dungeons to clear but by no means is it the hardest.

In a team, work out who is doing what, its better. Fastest player needs to give to the boss, second and 3rd fastest by way of movement speed, need to do most of the NPCS killing..... you want hard hitting skills not damage over time skills....  the npcs are not that hard to kill, there is just a lot of them and they respawn....
