25 minutes to kick off the dead knight of which five minutes has been wasted because of my carelessness to awake the little demon. Then I will share my experience with you.
At the beginning, there is no need to clear away all the demons, I immediately go ahead straightly to the little demons just in front of the BOSS. The slaughter of the little demons means to me the next slaughter with the BOSS. As for the way to run, it depends wholly on your instance which means how you will bypass the little demons, with so many difficulties since there are 110 of them around you.
Just follow the route to kill the BOSS:
As for Spider—go ahead to the little demons that are closed to him and kill them firstly, the BOSS immediately. After then you should go inside and destroy the crystal.
How about the duchess? I have guessed right the immediate slaughter of her after bypassing the little demons.
Just use the same method to deal with the pallid XX and BOSS, even the town master. Remember to destroy the crystals after your slaughter of BOSS.
    We will come to the next step. It is troublesome and nasty to deal with Abomination and skeletons in the front of the dead knight. You are supposed to attack all the little Abomination firstly and then the huge Abomination and BOSS. After the death of BOSS you will come across skeletons and corpses, with little blood while a lot in quantity. For those remitted of team-attack skill it will present them a big trouble. Therefore you should try your best before you attacking the Abomination to guide all the Abomination BOSS to the left side of the dead knight since the skeletons will show up in the right side. After all the successful attack you should right away drink some water and keep on eyes on the things on the floor. Elves can retreat out of others' sight and have some drink. Then since you have be full you can attack skeletons now. Warriors can cleave, windwhirl, and bellow at them.
    By the way, when you have attacked the little Abomination you can go back to get some holy water which will help you to deal with the little demons. It is a prerequisite to kick off all the little demons in time since all of them will come back to blood. You can take medicine liquid with you.
