Rules are in ER3145 . . . but I am not sure it has a TM entry though I maybe looking in the wrong version. I am not sure if its like MASC or Supercharger for equipment purposes- built into the chassis or pod-able equipment so Omnis can mount it.
Best to think of it (and it really is) like MASC for your heat sinks. I have yet to have it fail on me, but to be fair I have only gotten to use the Lament once on the table top. No idea if its in MM yet, but its something I hope is working.
