It's going to be broken by the Advantage/Disadvantage query, unfortunately. The sheet has the required code in the sheetworkers for Reliable Talent, and I did make a request for that to be made available to the user (like @{rtype}, but an @{rtypeRT} which has the necessary leading { brace inserted dynamically so the user can use grouped rolls etc.), but it was ignored. You could try again over in the 5e sheet thread, but I've given up. What kind of game are you in? Is API available? The most straight-forward method is to use !chatSetAttr to make these changes: You'd need a custom @{rtype} based on your preferred advantage rolling type - I'll use Query Advantage as an example, as it's the most complicated one. Your clockwork soul version would look like this: {{query=1}} ?{Advantage?|Normal Roll,&#123&#123normal=1&#125&#125 &#123&#123r2=[[0d20|Advantage,&#123&#123advantage=1&#125&#125 &#123&#123r2=[[@{d20CSnest}|Disadvantage,&#123&#123disadvantage=1&#125&#125 &#123&#123r2=[[@{d20CSnest}} You also need to edit both the core d20, and the @{d20CSnest} we've referenced above. @{d20} becomes this: {1d20cs20,1d0cs0cf0+10}k1 while @{d20CSnest} becomes this: {1d20cs20,1d0cs0cf0+10}k1 the "cs0cf0" is optional, it gives it a blue colour which isn't used much, a nice reminder that Clockwork Soul has kicked in. I prefer the 1d0 + 10 to the 10d1 which Aaron had above, just because it makes a bit less mess in the tooltip. With no API, it becomes much more tedious to implement. You can manually paste all of the above into the Attributes on the sheet, which has the advantage of working with all the sheet rolls. The obvious disadvantage is the amount of busywork for a 1 minute ability. Touching anything on the sheet that triggers a related sheetworker will also kill your changes. If you find that you're mostly just attacking while the ability is up, you can save the @{rtype} above as @{rtypeCS}, and the core die rolls as @{d20CS} and @{d20CSnest}, then make a new version of your core attacks referencing those 3 Attributes instead of the default sheet ones: always reference @{d20CS} from base macros, @{d20nest} from within a Query (like the advantage query). You've then got permanent Attributes that the sheet won't touch, but you'll need custom macros for any ability check/attack/save which you want to function with it. If you use "always roll advantage", you don't need the second, HTML-escaped die roll Attribute, and it's a little simpler. Again, tedious stuff, made more irritating by the fact that sheetworkers exist which do all the work we need, and throw it together for Reliable Talent rolls, but we don't have access to it.
