For aura(s) in line of sight, make spellcraft checks to determine school. Magic areas, multiple types or strong local emanations may distort or conceal weaker auras.What happens if the invisible creature moves depends, at least partially, on where it moves. If it moves out of the cone, clearly, the detecting creature must re-direct the cone and start again at step one. If the invisible creature moves to another point within the cone, then:Round 1: no changeRound 2: potential for change based on the previous round (1) if there was no aura but there now is oneRound 3: potential for change based on the previous round (2) and current one, based on change in number of auras and possibly the strength of the most powerful in round 2 being different to the strength of the most powerful in round 3So if an invisible creature stays within (or enters) the cone in or before round 2 and moves but stays within (or if it enters) the effect in round 3, you detect that there's an illusion in round 3 and, depending on the number of auras you detected in round 2 and the number you detect in round 3, and on the possible change in strength of the most powerful aura you detect from round 2 to 3, you might be able to deduce that there's an invisible creature in the cone. If you do, you'll know what square it's in, that round. Any subsequent rounds that it moves within the cone you're concentrating on will make it fairly obvious that there's a mobile invisible entity there and you'll know what square it's moved into.Basically, from the third round of concentration onwards, I'd rule that magic auras that move within the cone are automatically located - but with the caveat already mentioned that multiple auras can distort or conceal weaker auras.</blockquote>
