Fortitude Save effect possible

Hi Folks

I'm trying to see if I can figure out how to make a "Gravity Grenade" effect/action that will have the target make a "Fortitude Save".

I've been looking in the wiki and a listing for the three common saves seems to be absent.

Any help would be appreciated.

Thanks,

Reg

Set up an action using the Cast dialog? https://fantasygroundsunity.atlassia...ts#Cast-Dialog

Thanks for that.

I had been trying to do it as a "Damage" or "Effect"
