3. The Damage Formula
damage = base damage × stale multiplier × charge multiplier × aura multiplier × fatigue multiplier
3.2 Stale Move Multiplier
The formula for the stale move multiplier is
This is explained below, including the definition of s.
In versus mode, for moves affected by stale move decay, this factor is
never 1. If a move is not in the stale move queue before being used, the value of this multiplier is exactly 1.05.
In versus mode, for moves affected by stale move decay, a move is placed in the stale move queue after it is used. The stale move queue contains nine entries, and each entry has a numerical weighting as depicted in the following diagram.
The left of the diagram represents the most recent move to be added to the queue, and the far right represents the oldest move to the added to the queue. Then we have
stale multiplier = 1 – s
where s is the sum of the values of the positions in the queue occupied by the move being used. For example, if the move being used occupies the .1 position, the .06 position, and the .03 position, then the stale multiplier is 1 - (0.1 + 0.06 + 0.03) = 0.81.
