USE REST AND [Rage] DAMAGE ASPECT, NOT THE SLEEP ONE
Can replace [Augur Reach] for [Primed Flow] if prefered
duration and calm and frenzy to increase the rate at which enemies die and how much you need to recast. Str isn't essential as mallet scales based on enemy damage, and range isn't a must cz enemies need to get close to the mallet to hit it and with too much range they cannot do this.
Another subsume option is breach surge. There is no need for survivability as you will stay invisible at all times
