NPC Spell Save (2024 rules), what's the trick?

[Hjorimir]

I can't seem to get FGU to see what stat is used for determining the DC of spells on the NPC entry. I have the following verbiage:

The illusionist is a 6th-level spellcaster. Its spellcasting ability is Intelligence (spell save DC 13, +5 to hit with spell attacks). The illusionist has the following wizard spells prepared:

But when I cast a spell from the NPC statblock, the spell save DC is 0.

The easiest way is to copy the text of an existing NPC from the Monster Manual (2014) and just change the spellcasting ability used.
The trait name must be Spellcasting; and it must include the text "spellcasting ability is <ability>".

The actual 2024 MM uses a different format for the Spellcasting trait.

There are actually two different sets of wording that can be used now depending on whether you add Spellcasting as a trait or as an Action. Both forms of words are detailed here. https://fantasygroundsunity.atlassian.net/wiki/spaces/FGCP/pages/996641934/5E+NPCs+and+Encounters#NPC-Traits

As Moon Wizard says the trait or action must be called Spellcasting.

Thank you both. I got it working. For anybody else who may see this, it's because I had my Spellcasting entry under the SPELLS header instead of under the TRAITS header. Once I changed where that was everything worked fine. Thanks again for the support!
