With the Roll20 D&D 5E sheet, I'm trying to add a special damage modifier to weapons. I created a custom attribute "custom_dmg" that is changed via macro. Currently it is set to 5. The problem is adding @{custom_dmg} to the Damage field on the weapon means on a critical hit custom_dmg is also added to critical damage: 1d8 + 5[custom_dmg] + 3[DEX] plus 1d8 + 5[custom_dmg][CRIT]. Default is only the weapon damage die should be rolled. So I thought adding @{custom_dmg} to the blank field at the end of the weapon would do the trick, however that field only takes a numeric value, example if I add "3" it shows in the chat window as + 3 [MOD] but if I add @{custom_dmg} there is no additional damage. Is there a way to modify the MOD field for weapon damage using a custom attribute? I'm trying to do this while clicking on the weapon(s) instead of another macro writing to a chat template with the result of the attack.
