ok i play a lvl 85 blademaster probobly with some crappy gear and a happy smile now i finished ultimate with killing end boss without dying once ( must be proud for something i guess) as my weapon is kinda crappy i checked out what i could find saw something interesting with a insect name mad Queen rash…something >< and saw that she exclusivly droped a nice blade so i happy whent after her in ultimate ready for some nice play…oh boy did i chew on a stick to large for me haha kicked her down to about 96% att best Before weaking upp in heaven like 15 times 
i mean end boss wasent even a mob compared to this one. i have like 11.7k hp dps att 22k and i couldent scratch her ? yeah i know there are some wisecrackers who will say ohh i just killed her in 10 sec flat without a sweat sure nice for you . but i am out of luck as a meele charachter i cant kill on range and this bug actually drop a desent weapon for once “thanks for that developers most gratefull for your humor” actually i have some nice hoard with legendarys like 130 different do i have something from the deathwisper or a nice sword a blademaster can use nope
i just wish i hade made Another choise in charachter blademaster is just a bust. R.I.P my poor blademaster:cry:
Run away when she does her red aura. That will save you a lot of trouble.
Like the poster above said, always run from her when she has the red aura. If you hit her while she has it, the aura will shoot life reduction projectiles which can drain you health in a split second.
She has very similar stats to a Nemesis. Heck, she’s pretty much the Beast faction Nemesis now that i think about it.
Insectoid…she is an insectoid, not a beast ! A giant EARWIG to be more precise.
Anyway, to the OP: as a blademaster your best strategies are:
- Eat an Aether Cluster;
- Avoid the Queen while the red aura is on;
- Stack Deflect Chance (this is one of the reasons ppl love Saboteurs).
Alternative strategy:
Get a 2h rifle called the Gutripper and one called the Scarlet Marksmen. Equip Vileblood mantle. Mad Queen should be dead in about 20-30 sec.
yeah i know about the aura it is a Death sentence to attack her only problem it is upp almost all the time all my kiting have just resulted in Death >< tried gutripper with the other stuff only one thing to say i am a meele charachter using a gun was a fun way to go about it but pointless anyway she heals faster then i can do range damage …using eather clusters helps for 8 sec then i have to wait 90 more for next use kinda worthless when Life expectansy for me is 10 sec perhaps 1 min if i do my best kiting and almost 0 damage. i can just kiss that piece of loot godbye
The problem you are experiencing is a common one for melee blademasters - or even just melee characters in general. Sense you can’t do (reasonable) damage from ranged either your gear is good enough to wade into melee and take her down or you get destroyed (or you tank her, but your DPS is so low she can health through it, also an option I suppose but more seen by shield users). Anyways it sounds like you just need better gear and/or build to take her down.
What about stacking Life Leech Resistance?
Also debuffing her could make a difference.
yeas i am frustrated because she holds a nice piece of Equipment that i would very mutch have my greedy hands on …not on the monster herself but i am frustrated by the fact the only mob in grim dawn i dont stand a single chanse against actually can have a chanse to drop a sword i need (any other boss drop more or less random loot witch Always is crap for me or usable by Another charachter ) that fact is making me angry not the fact i die and got to eat grapes with the angels…so my only option is a ranged character who is very favo with the game machanic of grim dawn. thanks for all the imput and sugestions 
She’s a DPS check so make sure you can not only survive her attacks, but also do a substantial amount of damage in her downtime (i.e. when her red aura is off).
What damage type do you focus on? Do you reduce resistances?
I find that respecing a blademaster to maximum 26/16 blade spirit with the pierce reduction constellation/aura will work just fine… assuming you have a lot of pierce/bleed damage. If you have a Belgothian’s Carnage relic you can actually call out a LOT of spirits since there is no summon limit. Just make sure you kite at a moderate distance since the spirits will not attack if you are too far from her.
Every now if you feel like it, then just blitz/shadow strike in to deal bleed (don’t try to execute her or hit her with multiple hits since that’s just a good way to get killed) and then blade barrier when things get hairy. She should bleed to death eventually.
I officially gave up on killing her last week… way too stressful and frustrating experience… She is pretty much impossible to take down with most melee builds, but is ridiculously easy and safe for casters, which is another reason why this boss is total bullshit…
It’s the only boss in the WHOLE GAME that I can’t kill with my commando… if you can kill ultimate Log and even a nemesis such as fabius, but you can’t kill this single boss alone, then yeah, no way in hell the problem is with your build.
Simply put, the Mad Queen is not worth the hassle, and if you want her weapon, just roll a caster and roflstomp her easily.
You can try Ulo devotion. You can nullify her aura.
