I am using a Rapid Strike Style Urshifu from the new DLC. What I want to know is how much damage Surging Strikes would do while holding a Sea Incense with 383 atk. I'm sorry I do not understand the calculation method.
damage = ((((2 + (2 * level / 5)) * power * attack) / (defense * 50)) + 2) * modifier * random Power is 25 * 1.2 because it's holding a sea incense. Modifier is STAB * critical, which is 1.5 * 1.5. Random is between 0.85 and 1. damage > ((((2 + (2 * 100 / 5)) * 25 * 1.2 * 383) / (250 * 50)) + 2) * 1.5 * 1.5 * 0.85 = 77 damage < ((((2 + (2 * 100 / 5)) * 25 * 1.2 * 383) / (250 * 50)) + 2) * 1.5 * 1.5 = 92 source
