I'm trying to make a Macro for DnD 3.5 where a skillcheck results in adding additional damage dice to an attack. I have the Macro set up, but the problem is that for the rules, the extra dice only goes up to a maximum of an additional 9d6. This is the table for the rules
10—14 +1d6
15—19 +2d6
20—24 +3d6
25—29 +4d6
30—34 +5d6
35—39 +6d6
40—44 +7d6
45—49 +8d6
50—∞ +9d6 (maximum)
And this is the Macro I have so far, since the amount of d6 goes up by one for every value of 5, I just used a floor for the total and divided the whole thing by 5.
{{Iaijutsu Focus= [[[[floor( ( [[1d20+@{cha-mod}+((@{level}+3)*2))/5)-1}}]]d6]]}}
I am going to put this macro into a weapon attack as a dropdown so it just automatically does it when the bonus applies, and I can turn it off but still attack with the same button if it doesn't. Any help would be greatly appreciated.
