suspicious death save

one of my player rolled a custom die for their death save instead of the death save button. When I hover over it, it show this /r 20+1d0cs>0cf>1  is this an attempt to cheat? I am not verse in the macros and custom rolls.

Possibly. Are they using the Beyond20 extension to roll from their character sheet on D&D Beyond? If not, then there’s no reason for a roll like that that I can think of. 

Certainly doesn't look like a macro that uses the Roll20 roller. There's some advanced macro syntaxes that could create that for a valid roll, but they are things that I'd expect the player to clear with their GM first (e.g. I let users in my game use a macro that presents a query that allows the user to enter the result of a physical die instead of rolling with the digital dice). EDIT: And Jarren's also hit a big possibility I hadn't thought of. The Beyond20 roll should still display in the standard roll template though.

Pretty sure that DnD Beyond and Beyond20 would not come up with that either unless they had a big oops.

Or is this something the player would have to have researched and known?

Could you post a screenshot of an example roll that you suspect? With the rollover tooltip showing the roll   And if possible a screenshot from DDB (if you’re also in the same campaign there and can see a history of rolls from the same time).  Gauss said: Yes, that is an attempt to cheat.

This is what it will look like using Beyond20 if 3D dice rolling is turned on for the character on DDB. (With the exception of the /r part)   If this did come from DDB using Beyond20, it shouldn’t have the ‘/r ‘ part, but would come through using the ‘npcaction’ or ‘traits’ template (or the ‘default’ template if you’re not using the ‘D&D 5E by Roll20 character sheet). But if it’s Beyond20 that would be a valid roll if they have the 3D dice turned on in DDB, because what Beyond20 does is take the actual roll that happened on DDB, and then recreates it on Roll20. If 3D dice are turned off then Beyond20 makes the roll directly on Roll20 instead of recreating it.

Guess it is another reason for me to disallow D&DBeyond in my games, will never know if someone is faking the roll except via repetition. 

I think it comes down to two possibilities: If they typed this in manually, they are trying to cheat. If they are using Beyond20, they likely rolled a 20 in that system and this is how it pushes the result to Roll20.  It's likely that the 20 in that expression is the result of random generation in the extension, injected into the chat message.  The +1d0cs>0cf>1 part is how the extension creates the proper coloration for their roll. 2 seems more likely.  If a player really wanted to cheat, there are far less obvious ways to do it.  Nested inline rolls which don't show the math, for example.  I would just ask them about how they generated it, and have them demonstrate it either via a screen share, or by hitting it in rapid succession to prove it's not a static 20.
