$$damage = base \cdot (1 - accs) \cdot (1 - type - dr) \cdot \begin{cases} 1.1 & \text{if in Appeal Chance} \\ 1 & \text{otherwise} \end{cases}$$

$base$: Base Note Damage

$accs$: Sum of damage-reducing Accessory effects (Necklaces)

$type$: Gd-type bonus/penalty from active Strategy

$dr$: Sum of effects of active Damage Reduction skills

To do: Damage is floored. But in which order?
