Add Herald of Agony to The Dark Monarch

As per the title.

Herald of Agony is by no means an overpowered minion build. Compared to most other minion builds it requires a lot more investment to even be comparable in damage. The best scaling (increasing maximum Virulence) also makes the downside of losing them faster with higher stacks even more significant.
