I too have a Robot-Dark MM and I chose Musculature because of the damage proc is for all damage that is done to include the pets. I then chose the Reactive to include the Fire-based damage over time, which is also increased due to the Musculature. I went with Mu for the Electric Cages that allowed me to Immobilize a group, hit them with Tar-Patch and then let the pets take them down from there. All in all it has worked for me.

May your days be filled with all the happiness, wonder and joy that bringing miracles into the world can share with you!! Congratulations and Blessed Be!!!!
