Combat Protocol: 

Civilian Intel:

• I don’t have Knull or Scream ranked so I used Medusa. She worked well

• I've had great success using CGR against Jack. I don't have Knull and none of my 7-star options came anywhere close to the 30 to 40 bars CGR got consistently.

• Scream does incredible against Jack, I was averaging 50 bars just by getting the sp1 fervor and nuking him with sp2

• Medusa’s decent against Jack, but avoid sp1. Once he’s armor broken, you can’t inflict any more and you stop building furies

• Knull is by far the best option. Just spam SP1 and he destroys. R2 unboosted did ~100 bars

• Knull cleans up Jack, I highly recommend. 

• Scream does incredible against Jack, I was averaging 50 bars just by getting the sp1 fervor and nuking him with sp2

• Medusa’s decent against Jack, but avoid sp1. Once he’s armor broken, you can’t inflict any more and you stop building furies
