I started questioning myself if UWSC even is possible with monks. Because i had nothing better to do i started some investigation. These are some of my conclussions.
A. These Quests need a monk with Spell Breaker because of Interrupts / Enchantments Ripping / Life Stealing. This also means they need a second team mate to make kills. B. These Quests do not need a monk with Spell Breaker. This means these monks can make kills for themselves. C. These Quests do need Spell Breaker but because there is a other monk nearby they can use there Spell Breaker. Clearing the Chamber C. Because everyone will be there until this monk completed the quest. They can easily use Spell Breaker on him. This quest does not neccesarelly have to be done by one monk. The first monk who is aggroing the graspings to open the doors can leave after that for another quest and leave this one to some else (probebly vale monk) Unwanted Guests B. / A. This quest does not need Spell Breaker but it does make i significantly harder. On the other hand taking Spell Breaker making this quest easier does mean you need a partner to make the kills. Escort of Souls B. Excessive Interrupts and energy draining makes SB a must. Imprisoned Spirits B. / A. Life Stealing comes along here but because these excist out of particulair small groups this quest might be completed without a SB monk but it does need "I Am Unstoppable!" for the Terrorwebs in the Quest. The Four Horseman B. This quest needs 2 SB Monk or maybe even 4 because the horseman carry Signet of Humility and therefore SB might not be echoable. Wrathful Spirits A.
So if all my theory crafting is right we would end up something like this.
