OVER 300K DAMAGE - Infinity Spearzon

Greetings to all! Not long ago I was dealing with the issue of a perfectly balanced build for the Infinity Spearzon. What I was able to do in the end, BUT then I thought, how much damage can I squeeze out of this character? - I got well over 300k!!!
I would like to share my concepts with you in video below ( just search it on Youtube ):

What were the maximum damage figures you achieved?
