Hello Masters,
this is my first public project and the first time I use GitHub so forgive me if I have made any mistakes.
There isn't much to say, as the title suggested this is yet another tool to calculate the damage of a servant's noble phantasm.
Now I can explain some of the UI components.
This is the main window where all the numeric values are inserted and the damage is displayed.
The first two fields are self-explanatory.
Buttons for the selection of Np type with the associated Card Damage Modifiers (i.e. buster 150%)
Fields for Attack Buffs 
and Attack Debuffs 
on the servant.
Fields for Card Buffs 
and Card Debuffs 
on the servant.
The Card Weakness Debuffs 
and Card Resist Buffs 
on the enemy go here, the former in the first field and the latter in the second field.
Fields for Np Ddamage Buffs 
and Np Damage Debuffs 
on the servant.
Fields for Special Attack Buffs 
(i.e. bonus damage against [dragon]) on the servant and Special Defence Buffs 
(i.e. defence against [dragon]) on the enemy.
Fields for Flat Damage Buffs 
(i.e. divinity) on the servant and Defence Cut Buffs 
on the enemy.
Fields for Defence Debuffs 
and Defence Buffs 
on the enemy.
Fields for NP Extra Damage of the servant (i.e. Beast Nero bonus np damage against the main 7 classes) and Damage reduction 
on the enemy.
Drop-down lists for the selection of the servant's class damage modifier (i.e. Saber is 1.0x), advantage modifier (i.e. 2x if the enemy is weak to the servant's class) and attribute modifier (man, earth, sky, etc.)
Buttons to calculate the Noble Phantasm's damage and to reset all the fields.
Fields where the damage is displayed.
Field for the Enemy's HP you want to test the damage against. The button 
is to refresh the display after the value in the field is modified.
