That makes sense, yes, but I feel it might be better to clarify in the text that this is intentional and not an oversight.
Oh, another thing I noticed was in the Advanced Prisms rules, there's no rules for how they act when they're damaged. I assume that for the Prisms that are just basic elemental prisms with an additional effect, they'll lose the +1 but keep the ability to use that element, but will they keep their additional effects? (I assume that the ones that need to be damaged to use their effects can't be damaged again, at least.) And what about the double-elemental ones? (I assume that the non-elemental ones just can't be damaged at all.)
Thanks for your reply!
