Effect Save Automation

[Stargrove]

I am trying to create an ability for a creature to have an ability to apply the effect Immobilize to a character and automate the characters Save DC roll after it has been applied so they have a chance to get un-Immobilized. I have created the automation on the creature as follows:

"immobilized"|Effect: Immobilized; Frozen in Place, SAVE:Will DC 24 [DC:24]

It gets properly applied to the character when they are targeted and I double click on the effect. Once it is on the character I see the four little buttons as expected and they say ON, ALL, VSBL, START, the text reads, "Immobilized; Frozen in Place, SAVE:Will DC 24, the Duration is set to 0, it shows the DC as 24, and the Init to Adjust On shows 18.

When it gets to that characters turn I had hoped it would automatically roll the Will Save against DC 24 for the player.

Hopefully I just created the effect improperly on the creature.

The DC in an effect is for information only and provides a reference for any manual checks. The exception to this is the flat check for persistent damage (PERS effect).

Immobilized, for example, has this note in the Effects Wiki page: "Handle DC checks for external force moving immobile creature manually."
