Just been messing around with the 200% more AOE on Rolling Magma mod. I spent about 30 Div on this build so far and it already does anywhere from 10-20m dps and covers essentially the entire screen. Each Magma ball does about 3m DPS and it hits usually 4-5 times but it actually requires aiming so you can screw up occasionally.

Open to suggestions on how to improve it btw!
