Initially I did this with 4 Drillarm1s for my personal challenge, but a friend convinced me that with enough boosts, 2 DrillArm3s could work as well.
At 3+ columns, Drillarm hits 2x with a knockback to back column.
At only 1 column, Drillarm will hit 3x.
At 2 columns, if attacking from the front, Drillarm will hit 4x.
With Fan, Drillarm can steal an extra hit in as Knightman gets pulled up once more.
Thus, with perfect timing, Drillarm can hit up to 5x.
[(80)*2 + 40] * 5 hits = 1000 dmg
80*2 * 5 hits = 800 dmg
Total = 1800 dmg
