Necromancers and monks don't have any interrupts as much as I know. But maybe with some points in smiting you might be able to use a smite attack to 1 hit kill the nightmare. I think reckless haste would be a bad thing unless you use shield of absorption to be able to take the amount of damage by a lot of squids/ smites.
Well the build would be doable with a 135 monk. The only shame is that the build doesnt have any visages Not a complaint tho, just pointing the hardship the graspings will be then since they drain ur energy :P
wouldn't work, the graspings daze you to dead. (I already tried it right after update )
The power of ss was (with the graspings) that they couldn't interrupt your ss because you casted when outside their aggro, making sure they didn't interrupt you. Now you gotta cast spoil while being attacked by the squids...
