You got me close enough that I figured it out anyway.
Even though it was no joy on the final result.
In the end, the script was:
Code:
doneif (tagis[Helper.Disable] <> 0)
~find every spell with the ritual tag
foreach pick in hero from BaseSpell where "Helper.RitualSpel"
~set the name to be the name & ritual
eachpick.field[CustDesc].text = eachpick.field[descript].text & " *ritual*"
