I'm trying to create an ability similar to a Dragonborn's breathe attack. The enemy would need to make an Intelligence Saving throw. The DC would be 8 + int mod + proficiency bonus.

I can get the DC to display properly in the snippet/description of the attack but on its action section (where you roll the damage). It displays the dc without the proficiency bonus. 

Anyone know what I need to do? I've tried copying the breathe weapon from dragonborns to the letter but I can't figure it out.

 
{{savedc:int}}

is it possible to add the {{modifier}} to the {{scalevalue}} is it something like {{scalevalue+modifier:wis#unsigned}}

Maybe. Try {{(scalevalue+modifier:wis)#unsigned}} instead though.

Is it possible to change a feature trait? For example I want to change a Monk's Unarmored Defense from 10+DEX+WIS to 10+STR+WIS.

 Not with snippets; they don't actually do anything other than display helpful information about a feature or trait. You could ask in the Homebrew Forum in general about adding a special Unarmored Defense AC calculation as part of a subclass feature or feat, but we regular users aren't able to replace the base features of a class.

How do you use classlevel to specify a specific class?

The classlevel snippet only works in sub-class features (or sub-class feature actions), so it always uses the level of the class that it is attached to.

I'm trying to add {{(classlevel/2)@rounddown}} and, no matter where I put it in the ability, it either does not show up at all, or it shows the actual code text and not the calculated number. 

Does anyone know why this is?

You can only use it in the “Snippet” fields attached to subclass features and their attached Actions. 

Well, I put it everywhere to test it, and it's not appearing in the snippit at all. 

After you add anything to, change anything on, or remove anything from any homebrew you MUST re-save the entire thing using the main [SAVE CHANGES] button under Basic Information or the system won’t pick up your changes. After that it can sometimes take up to 20 minutes for those changes to push through to the character builder/sheet.

These will be useful! I made the mistake first thinking I could use them in description text, but I get it now. 

Is there a similar method to have dynamic effects like this in description text?

No. Description fields are only for the full explanation so everyone knows exactly what causes the calculations. The Snippet fields are only for display on character sheets and are intended to utilize these dynamic calculations to simplify and abridge those full descriptions for display purposes.

Thank you, IamSposta, you've been very helpful! I eventually realized this on my own lol... I also figured out that if I go in and manually switch to an different patron, it instantly updates the homebrew patron I'm working on, without having to wait for the sever to update or whatever it's doing. 

so i want to make a feature that scales when you level a number of hit die equal to half your level rounded down plus your spellcasting modifier how would i formulate a snippet for that?

Example when you cast sleep you can add an additional warlock Hit die equal to half your warlock level rounded down minimum of 1 plus your charisma modifier

so what I want to happen is that at level 1 they can add an additional d8+charisma mod to the roll of the spell that scales as they level up

so lvl 4 thats 2hitdie level 6 3hitdie, level 8 4hitdie

Is it specifically for a Warlock subclass? If so then I believe you would use the following snippet:

{{(classlevel/2)@min:1}}<strong>d8</strong>{{modifier:cha@min:1}}

Thank you for the info

Happy to help.

I'm not sure if this is the place to ask, but is there anything like this for things that aren't snippets? specifically, I'm trying to make a racial ability that lets you use the charm person spell with the save being 8+cha. there's a line for changing the DC, but it seems like you can only put a fixed value in instead of an equation.

This isn't really snippet related; but to change the calculation to be Charisma based you want to set the Ability Score to CHA on the Spell entry, however this will result in a calculation of 8 + CHA + proficiency not just 8 + CHA.
