Checkbox modify Attributes

Hello, sorry if this question already exits, but i did not find anything with the search function. I'd a checkbox section to my custom character sheet for wounds on specific hitzones. When there is a wound specific attribute is lowered. e.g. if there is a head wound the attributes MU/KL/IN lowered by 2 and the INI attribute is lowered by2d6 This goes up to a maximum of 3 wound per hit zone so there would be 3 checkboxes for it

When you set the value attribute of a checkbox input to 1, the value of the attribute associated with that checkbox will be either 0 or 1. You can multiply that with numbers in a roll to turn parts of a roll on or off. For example: @{ini} - @{head-wound-1} * 2d6 That would give you the "ini" attribute when the "head-wound-1" checkbox is unchecked, and would give you ini - 2d6 when head-wound-1 is checked. It can make for some ugly macros, but it does work.

just works as i want it, thanks
