It is daunting, there is a simplified Pathfinder sheet without as many choices. but the whole party has to use it. For witch hexes I use the Abilities list for my Shaman (which uses witch hexes) . but you can see the dropdowns to set Su, and use Int for the ability, and i think it's 1/2 level as the "spell/ability" level which gets you 1/2 level + Int for DCs. You have to write the type of save in the "Save" field (will, fort, etc) so the DC will print when you click on the button to "roll" Then for "Range" put "number" and 30 for the feet, and in short description you can write rolls like [[1d8]] or whatever
