- The box surrounding the result should be green or red if there was a critical I believe so unless your inline includes multiple dice rolls, any green box would be natural 20 and any red box would mean natural 1 . I believe if there are multiple crits or varied nature, the box is blue, not sure. - Criticals in Next are mostly used for combat, ie: attack rolls. Calculating damage from critical is very easy since you just need to add the maximum value of the damage dice. Therefore, something like this: /em ?{Attack emote|attacks!} (ATK: [[?{Attack dice number|1}d20?{drop or keep}+@{CharacterName|TOHIT}+?{other bonus|0}]] / DMG: [[@{CharacterName|DAMAGE}+?{other bonus|0}]]) This macro assumes an attribute on the CharacterName sheet for TOHIT (which can be for melee attacks in the 1st field, and ranged attack for the second field, in which case, just add |max) and another with DAMAGE (which includes the dice number for damage as well as bonus to damage, such as 1d8+2) When you run this, you'll have various prompt box appearing. Most of the time, these prompts can be defaulted and you just press enter, enter, etc. However, you can work customize the emote attack, then the dice numbers (for advantage and disavantage attacks), then decide if which you keep (just use "dl1" for advantage and "dh1" for disadvantage roll), then add whatever other bonus from context you need (can be another dice and whatnot, for example if your sword is on fire for one round, just type 1d4), then the same for damage. If the attack roll is a crit (green box around it), just double check quickly to make sure it's a natural 20 by hovering over it, then add the max damage to the damage roll (for example, if you do 1d8+3, just add 8 to the damage). Been using this macro for couple sessions and it works fine, especially if you like keeping things clean in the chat, while being able to quickly type in emotes when you attack.
