This is for Classic Traveller '77 edition. Many of the weapons do something like this: 3d6-8. But they will always do a minimum of 1 point of damage. So my original macro is this, which can give a negative damage result: &{template:default} {{name=@{selected|token_name} shoots @{Target|character_name} with his body pistol}} {{To Hit roll=[[2d6+0]]}} {{Damage roll=[[3d6-8]]}} I tried searching the forums but hard to pin down exactly how to search for what I wanted. I found a thread that suggested this at the end: &{template:default} {{name=@{selected|token_name} shoots @{Target|character_name} with his body pistol}} {{To Hit roll=[[2d6+0]]}} {{Damage roll=[[3d6-8]]}}kh1 That kh1 doesn't seem to do anything for me. Any suggestions for the above formula and where to add syntax to set a minimum damage of 1, regardless of the negative result? For now, players just read a negative number as 1 but would like it to work correctly :)
