I figured this would behave a lot like my awesome [Ohma] build, less efficiently because the Viral damage is higher than Electric, but it's also got crit where [Ohma] doesn't. Not building for the heavy attack energy ball, but in another configuration, I replaced [Blood Rush] and Cond Overload with the Sacrificials, and [Organ Shatter] with the Amalgam version.

Testing it on the SP dailies after ranking and forma'ing it up, it worked just fine. Killed very quickly at higher combo count.
