Create an attack action with proficiency bonus damage

I am trying to write a 5.5 version of the Genie Warlock.

For this feature:

Genie's Wrath: Once during each of your turns when you hit with an attack roll, you can deal extra damage to the target equal to your proficiency bonus. The type of this damage is determined by your patron: bludgeoning (dao), thunder (djinni), fire (efreeti), or cold (marid).

I added a class feature called Genie's Wrath, with 4 feature options (one for each genie type).

Each option, like Djinn's wrath for instance, contains an action with the same name:

Action type: General 

Display as attack: Yes

Activation type: Action

Damage Type: Thunder

Display as attack: Yes

Fixed Value: +2 (the base proficiency bonus)

This snippet:

 Once during each of your turns when you hit with an attack roll, you can deal an extra {{proficiency}} damage to the target. The type of this damage is Thunder.

And this description:

 Once during each of your turns when you hit with an attack roll, you can deal an extra {{proficiency}} damage to the target. The type of this damage is Thunder.

Then I added 4 level overrides:

The idea would be to update the +2 proficiency bonus with the correct number at the right level.

This is not working however: The damage bonus in the attacks is stuck at +2 even at level 20. And I tried changing the char level up and down to refresh the page. 

Also while the snippet {{proficiency}} is working in the action snippet, it is not working in the action description, where it appears as {{proficiency}}.

Any tips on how to fix these 2 issues? :)

Snippet code only works in snippet fields. It does not (and is not intended to) work in the description field, which isn't character-specific.

For the other thing, the Fixed Value only works if there's a die roll involved. I think if you add a die type but set the number of dice to 0 (not blank) it'll work.

Ok good to know this thanks :)

Is there anything that works in the Description as well?

 This is weird 

On the action I put down

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

(What does "IS PROFICIENT" do actually?)

But when I save it the action, it only says 0d6, completely omitting the +2 

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

 ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

However, in my level overrides the  calculation appears correctly.

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

And when I update the character sheet, the action displayed under attacks now does not give a number at all. 

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The description field isn't meant to be character-specific. It's the static text that appears in the subclass definition, so it's not supposed to have dynamic stats like that in it. That's what the snippet field is for.

"Is Proficient" means that it'll add the character's proficiency bonus to the attack roll.

As for the rest, if that's not working you may be out of luck, I had heard you could do it this way (with the 0d6 thing) but that was a long time ago.

Yeah, it's broken :p

Thanks for helping anyway.
