A defensive build for [Ash]. Lull's augment can be triggered by bladestorm attacks as well as manually or with [Fatal Teleport]. All you have to do is put enemies to sleep and every so often cast bladestorm on one of them. Any new enemies in the area will be hit with [Endless Lullaby] and supposedly everyone can be kept asleep for over 40 seconds on one initial cast of lull. This build is almost entirely for solo play as any allies you have will shoot and thus wake up or kill any of the enemies you have sleeping, meaning you can't use the augment. You can use pretty much any melee you want as you really only need bladestorm for the [Endless Lullaby] procs. Personally, I keep a [Sancti Magistar] around on this build to heal defense targets when needed.
