This damage calculator requires you three things to show the result. They are Level, Strength and foe's Defense.

The damage settles near the upper limit of the random number range (10%). If the damage is at 500, the actual value takes somewhere in a range of 450-500.

Foe's defense is defaulted to 150. This is the average defense of the last dungeon's enemies.

Hassou Tobi is a magic damage with 'Skill' element, so use the Magic Skill Damage Calculator. It cannot be compared to physical damage as the calculation formulas are completely different.

Full moon is for Moonlit Mochi-Making, New moon is for Sneak Attack, and Waxing moons is exclusive to Crescent Slash. Each skill increases the number of attacks for the corresponding moon age.

Loyalty is an item for magic, such as Loyalty Slash, whose power relatedly changes with loyalty. The power is halved for every 1 loyalty level decrease (not damage).

The Sake combobox is for Toasting Strike, Drunken God Kick and Confusing Stumble. There are 12 levels of drunkenness from 0 to 11. Sake showing "Duration: Short" raises the Drunkness level by 1 and "Duration: Long" Sake raises it by 4. Each time you drink it, the power increases by 25, and when it comes to the 10th, the power is 250. Only the final step: 11th is unique and its power is (not 275 but) 255.
