Automatic Regeneration for token when at half hp?

Im running DnD 5e and have a monster that regenerates 10 HP if they are below half HP. I'm using the OnMyTurn API script to add the HP through tokenmod automatically. Right now for the OnMyTurm ability I have below: !token-mod  --api-as -<MYDM#> --ids @{selected|character_id} --set bar3_value|+10 This works except it adds 10 HP at at the start of each of the monsters turns. I tried to create a query as below ?{Half HP?|Yes,!token-mod  --api-as <MYDM#> --ids @{selected|character_id} --set bar3_value|+10 | No, } This fails and pipes the text of the command into chat. What am I doing wrong?

When OnMyTurn triggers, it is the API that is running the ability - the API has no way to select a result from a query.  I havent used OnMyTurn, but you might be able to whisper a button into chat that you can manually click to run that command.

Thanks! Sending a button to chat worked.

Great!
