This combo nukes bosses. Hazardous propulsion sends out rockets each time you use your class ability and whenever these rockets hit an enemy, you get a 35% damage buff to all your rockets. But it only checks if the weapon deals explosive damage which means things like rocket sidearms can also benefit from the buff. But with grand overture, you can build up your 20 missiles, use a class ability to get the buff, then blow your load to deal and bunch of damage.
