I don't want to be misleading. I had Grok 3 try to figure this out. It's proved to be obviously beyond me. Grok 3 with a little help from me on how to write to the NPC Character sheet directly got farther than I could. But it couldn't quite complete the process despite my best effort/thoughts on what flags we were missing to clue Roll20 into the fact that our attack block was an attack block. Basically, the insertion of the attack into the NPC character sheet is not recognized as an attack in Roll20. Despite my best efforts, I cannot figure out what the UI manipulates to flag an attack block on the NPC character sheet as a clickable attack block with a functional cog. Hence my desperate appeal to the forum. I can write in the block, but can't make it work. The red outline around my created block also seems to indicate Roll20 is quite aware I have done it incorrectly. But, with a little Grok 3 assistance, here is as far as I got. This is as far as I was able to get testing how to insert a block under actions as a melee attack into the NPC sheet from the API. I am not posting the rest of my actual script for the spell implementation as it's not relevant. Happy to share it though if someone wants it. Everything works with the token creation and chat log output in that script. It's just writing to the NPC Character sheet (specifically in the actions block, I can write to HP and AC as intended) that I am too inept to sort out. on("chat:message", function(msg) {
