Free 5E extension to prompt the GM when reaction is triggered.

Hi, great extension!

I have a couple of questions for thing I can't get to work as intended.

- What's the language I need to use for the extension to recognize when a monster/NPC fails a saving throw? The instructions say "The monster or an ally fails a saving throw.", but I've tried several version of this wording to no avail.

- For "a creature (within X feet) of the monster casts a spell", I have managed to get the reaction reminder to pop when I add the monster to the CT, but I can't get it to pop when the action is performed. What do I need to do for FGU to recognize that someone is "casting a spell"?

- Last thing, is it possible for the extension to recognize double conditions, such as "the monster is hit with an attack or fails a saving throw"?

Thanks for the great work!

Hello!

Thank you for the kind words and for your questions!

- Saving throws. The phrasing that the extension is looking for is [ another | other | ally | allies ] ... fails ... saving ... throw. I added an example to the description in Forge and GitHub.

- Spell casting. In my testing and usage it works when I press one of the "Save" "Damage" or "Effect" buttons on the character sheet, see the attached screenshot.

- Multiple conditions. Right now the extension stops matching when it finds one condition. Technically it is possible to continue, but there are some caveats (possible false positives). I will play with this idea and see how it goes, but for now it is not supported.

I hope it helps. If you have further questions or something doesn't work, I will be happy to help.

Cheers!

Thank you for the reply!

I'll test the spell casting option as soon as I'm home.

As for the first bullet point, does that mean that the trigger for the reaction can't be the NPC itself failing a saving throw? Does it have to be another creature?

To be clear, I'd like to know if a wording similar to the one used for AC (for scenarios like the Shield spell, for example) but for saves would be possible. For example, something like "If Monster_name fails a saving throw, it can use a reaction to..."

Cheers!

No, it doesn't have to be another creature. There are two different programmatic triggers and my mind focused on one of them

The words for the creature itself failing saving throw is [monster name] ... fails ... saving ... throw. Typical example would be a legendary resistance, like "When the XX fails a saving throw, it can choose to succeed instead." That should work. If it doesn't - please let me know.

EDIT: this trigger is currently only works in monster traits not in reactions section, because I originally made it to handle legendary resistances which are always in traits section.

Oh, ok. That explains why it wasn't working for me.

Thank you for the update!
