Hello,&nbsp; I've been making a global macro that utilizes a template (<a href="https://help.roll20.net/hc/en-us/articles/360037257834-D-D-5e-OGL-Roll-Templates#D&amp;D5eOGLRollTemplates-Attack" rel="nofollow">https://help.roll20.net/hc/en-us/articles/360037257834-D-D-5e-OGL-Roll-Templates#D&amp;D5eOGLRollTemplates-Attack</a>). The reason I'm making this macro is so that I can roll different NPCs actions without having to open their sheet. I utilize the @{selected|...} attributes to make their attack actions. My last snag is understanding how roll20 automatically determines critical hit damage dice in character sheets and somehow apply that knowledge into a template (npcaction) I'm using for my global macro.&nbsp; Also, for reference, critical hits in DnD 5e is that all damage dice are doubled. You do not double modifiers to damage. Simply, you double all dice on a crit. I want to know if there is a way to auto-determine what critical damage should be, using a template in a macro. In a template, you fill out parameters to have them roll values. Somehow, the template does &nbsp;know if an attack is a critical success and then adds additional damage ({{crit1}}) to your initial damage roll({{dmg1}}).&nbsp; I know there is a parameter for {{crit1=&lt;dice roll&gt;}}, it's clearly explained that whatever dice I put in this field will be rolled when the damage is crit. But that requires me to determine what dice should be rolled and I know Character Sheets somehow auto determine critical damage with NPC attack actions. The issue I have with this is that I do not&nbsp; For example. Let's say a fighter (16 STR) has a greatsword (2d6 weapon damage).&nbsp; the damage parameter would look like this: {{dmg1=[[2d6+3]]}}, rolling weapon damage and adding 3. The crit1 damage, as per 5E rules, would be an additional 2d6 damage. Is there a way to make the template auto calculate the critical damage from its dmg1 parameter? Is there some helper function I'm missing?&nbsp; Again, I want this global macro to do the calculation so I can use the same global macro and make full use of the @{selected|...} features to get info from the NPC's repeating actions.&nbsp; Hope this makes sense, I've been banging my head against the wall trying to figure it out. Any help would be appreciated. I do not have access to the API, but I assumed bc the character/NPC sheets in roll 20 for 5E have a way to auto calculate critical damage from the single damage parameter given, that the templates would as well.&nbsp; Thanks, Aly
