Serious? "They" is referring to SC in that second sentence. Again if you'd use simple context clues it is easy to figure out which I'm referring to but I suppose I have to be very direct in my terminology every sentence or people mistake you for being an idiot who doesn't understand what each resource in this game does -.- I don't play on DMM at all so saying "on Nutaku" is redundant as I'm not confusing things with the DMM side. By SP crystals I obviously mean the Piece of Crystal items used for SP summons and SP summons only that can only be used with Piece of Crystal. Is that clear enough yet?
