@Ifusaso - aBB and P do stack, or rather, they are additive. You can have a Leorone 70% atk buff and a 50% brute elixir buff active at the same time. You can add an Ore for additional boost.

@Mamerge - Ifusaso is right about the crit and spark multipliers though. In your example, the spark multiplier should have been 7.5. That's because the hits that don't spark still get a '1' multiplier. To make this simple to demonstrate, assume Mifune has a base hit of 100. When he sparks, the damage is 150 (1.5x) instead. So, if you get 3 sparks, total dmg will be 750 (100+100+100+150+150+150). The proper way to add this to your formula would be SparkRate% * SparkMultiplier + (1 - SparkRate%).

Lancia, at 6* SBB10 gives a 40% Atk boost, not 120%. The highest atk boost is Michele SBB10 at 85%

Finally, your bb attack booster is incorrect which is messing up your base hit calculation. It should read:

= 2109 * ( 1 + .75 + 0 + .5 + .5 + .5 + .85 + 5) * (.7 * 1.5 + (1 - .7)) * (1.5) * (.5 * 1.5 + (1 - .5))

= 2109 * 9.1 * 1.35 * 1.5 * 1.25

= 48,580
