Well, this has bothered me for a while, but I guess I'll open a discussion on it now. Why is it that a Pillar of a particular element costs 4 Electrum, and yet a Pendulum of that same element costs 16 Electrum? Granted the amount is still much less than that of say a Dragon, but why exactly does it cost 4 times that of a Pillar when it provides nearly the same effect? I could even understand twice the amount due it potentially producing two different types of quanta, but 4 just doesn't make sense to me. Thoughts or explanations anyone?
