What about taking it solely for flesh cannon ?.
Never played a Necro so I have no reliable info about flesh cannon usability and use cost.
It could work.

A different playstyle to Sorc2 since you don’t have the command skills. As you can see, he did not even use skeletons here so he is basically playing like a Necro1.
@Ellyr has created a great guide which has covered the discovered mechanics of Featherfoot. Thanks for the work involved. I will post the link onto the top of this thread.
