Video

@reedpipes

Thanks for the reply, first thing I would like to say is that I have uploaded this video on basil on behalf of my friend/guildie.
The first three comments were already mentioned by the author in youtube description, so I won't comment more on that.

The 4th comment is a very good point, and I will make sure he comments (depends on screen res of course). 5th point emphasise on the characteristic of dual blade, a fair statement to leave.

About the last points I will make sure my friend to make a comment about it (include in description most likely, not optimal but completes the video I guess if the video and description were to be combined), he kills oz with pb first as he can eliminate her VERY fast and is of the only annoyance for db on v2, besides mihile's dr, which he won't cast until he is damaged a fair bit (70%). The next question intuitively would probably be, how does he do other 3 bosses before mihile lol, and I'll have my friend to comment on it again.

Again, thanks for the feedback.

empress as a db is ridiculously easy.

In general, you should try to never let empress face to the left, since if she does so, she can use tornado and phoenix, whereas if she faces the right, she can't use either. Tornado and phoenix do a set amount of damage each, and although i've never been hit by tornado, phoenix makes a section of the ground burn for a couple of seconds, and if you go into the area while it's burning, you receive 7k damage per second.

If you use CoH when any monster is in DR, you won't take any damage. Damage dealt by CoH, however, will be 1 for all lines when the monster is in DR. When the monster is out of DR, CoH's damage will be normal. Thus, CoH is useful to let a db know when the monster has DR on or not.

Oh also, don't forget to mention that empress has a damage reflect that lasts for 20 seconds and has a cooldown of 80 seconds (after dr ends, empress will dr again in 60 seconds). Also, cooldown for mihile's dr is 70 seconds, not 60 seconds. Mihile usually casts damage reflect immediately after the 70 seconds are up but empress likes to take her time once her cooldown is up. Empress usually casts dr after 80-90 seconds are up.

Also, it's hard to determine where 70% of mihile's hp is, so what I do is that I mark the place a little left of the seventh buff of my buff. (my screen resolution is the smaller one, the 8XX by 6XX pixel one.)

key: [buff#]

[9][8][7][6][5][4][3][2][1]

right here is where 70% of mihile's hp is.

also, assuming you have a lot of avoid stat (I have 7k, and if you're going to attempt empress at all you should have a lot of luk and a lot of avoid), db's should never get hit by empress. Even when empress potential locks me, and reduces my avoid to 2k (b/c of the luk% and luk deficit), I still rarely get hit.

Because of db's godmode, stun from irena and web from ickhart shouldn't matter at all, since you have to take damage in order for stun and web to work. db's should only worry about mihile's dr and oz's skill lock.

In order to only attack oz, irena, hawkeye and eckhart, you have to wait until mihile separates from the pack and then you have to use flying assaulter and/or tornado spin to push mihile away from the rest. Then, use mirrored target on mihile to make mihile stay at one side of the map and push the rest of the bosses to the other end. Then use blade fury to kill the four. Once you move onto mihile, it's much easier since you don't CoH any other boss and only CoH mihile to see if mihile's dr went away or not.

you left out a lt of things lol.
