Aria seemed fiendishly amused by the idea of dropping the prismatic sphere on the ooze, and grinned. "That sounds more appealing than getting close to it ourselves...especially because, I should say, oozes are one of the most difficult sorts of monsters for me: can't deal precise damage without certain magic like my bracers...and I'm not sure which side would be their 'back' to sneak up on or get around to when they're distracted, you know...maybe I could get ethereally through the column - although that seems risky, I wouldn't want to phase in and be shunted into the surface of the sphere! Or we could use your or our items' dimension-door or teleport magic to go straight inside. The ward over the whole chamber seems constant and steady, but I can't tell what it does - the sight lets me see the presence of aura and their rough level of power, but not understand what they are exactly, the way detect-magic magic does for those more learned at such things. The statue is still magical; in fact it has two auras. And the blob and of course the prismatic sphere are magical."<br/><br/>Kass's spell-knowledge, meanwhile, would deduce that the sphere might or might not drop were the pillar under it destroyed, depending on whether the sphere had been cast on and in effect centered on and 'affixed' to some subject-to-gravity object inside it such as a statue like those on the other pillars, or whether it'd been cast on on some point in space. She would also recall that one of a prismatic wall of sphere's several effects was to destroy objects passing through, and so the sphere did drop onto  the ooze, it might well slay it (as there was a good chance such a spell could slay most anything), but its 'violet' layer also might destroy the encased statue and other objects it touched (whether they passed into it, or anything currently inside it passed out).<br/><br/><br/><br/>The relayed info about PS is just from my own reading and inference, you may correct or infer otherwise from your reading. In other words, if you think I wrote something which contradicts the rules, assume the rules are right, rather than this instance being 'customized' or 'houseruled'. In-character, with Kass's Spellcraft  she recognizes and 'understands' the effect, as she will any nonepic spell effect 20 out of 20s time by by taking 10 on spellcraft (on the "Identify a spell that’s already in place and in effect" at DC 20 + spell level).
