Since they are instantaneous, are Blocking spells exempt from rituals?
Blocking spells have 0 casting time, but that doesn’t exempt them from the ritual requirements for spells. If your level means you need to speak or gesture, and you can’t, then you can’t cast the spell. (Although at skill 9 or less, twice 0 is still 0, so there’s no effect on time.) Assume the words and gestures are very brief; e.g., “Stop!” and a raised hand.
