Hello, I was wondering if there's a way to count how many instances do exist in a given list without Pro subscription. Example: a spell list, let's say level 3. I know that right call is to be made this way: repeating_spellbooklvl3_$0_spellcast counting from 0 onwards (using 5eDefault), but how do I know how many $X there are inside my list? I'd like not to modify it every time the PC gets a new slot.
