Turns out that booping a dog with the Tractor Canon is really effective...

The number for the nova bomb is 590,602 (without the 25% elemental boost on Raid gear) on a 48x stack.

Haha! Is that the John Deere canon or the Caterpillar canon?

So your cannon just took the shield down, correct?

Nah, the dogs don't have shields. The canon did 32,670 damage and applied the buff which increases Void damage (new with Exotic improvements in S3). So my grenade and nova do way more damage than normal.

Ah! Thanks for explaining!
