Need help with GM only rolls for fresh Waterdeep campaign

Hey Mike S. -  What character sheet are you using for this game? You should be able to update this in your Game Settings page under the section titled Default Sheet Settings . Once you update things in that section, make sure to load back into the game, go to the Settings tab, and under the section titled Experimental Features , click the button called  Apply Default Settings . This will push the settings update you made to all the sheets in your game, so be careful.
