Macro Help

Here is the macro: [[1d8+@{Dyrk|wisdommod}+floor(?{Spell Slot Level|}-2)d8]] Here is what it outputs: (3) + 5 + floor(4-2) The "d8" just disappears. This is a spell that increases in damage every two levels. I am trying to make it so that I can just put it in the spell level and it will automatically calculate the damage. The macro works fine without "floor()", but once I put that in there the d8 at the end just started to not show up. Any tips?

You can't use any functions for calculating the number of dice to roll. However, the number of dice is automatically rounded to the nearest whole number (0.5 rounds up). If you need floor() functionality, subtract 0.5 from the calculation.

So do -2.5?
