For every fired bullet formula, damage per hit is decreased by 10% for every bullet that hits the enemy after the first shot. (e.g. firing a 3-hit bullet formula will damage the Aragami at 100%, 90% and 80% respectively).
For each bullet formula fired, if three instances of bullets hit the same part at the same time, damage calculation for the 3rd bullet will be significantly reduced.
Status ailment attribute does not damage the Aragami but is accumulated to a certain counter which determines whether the Aragami will be inflicted by the status ailment or not.
Recovery bullet attributes are fixed.
The type of Gun used does not directly affect the damage a bullet does.
