PoE Shield Crush, ShazzamPoe builds

Hey guys, been putting together some thoughts around the new gems now PoB has been updated and ran into an interesting idea I'm trying to build out PoB: The basic idea I'm considering is using Chieftain to power a fully fire converted shield crush which then can trigger a number of different spells from the battlemage. Depending on what spells we might pick here (I've been messing with Reap/Discharge) I think the numbers could be there to make something fun out of this combination of skills although its not going to be a meta kill
