What happens when an Aegis is cast around an exsisting Aegis? (second one is a larger area)
Cast by the same magi?
Cast by different magi?
Higher level than existing?
Lower level than existing?
The general consenses that we're leaning towards is that the 2nd one overlays the 1st but does not remove/supress it. So if you cast a higher level around the 1st it acts like the higher to anyone else.
If Mage B cast it around the original by Mage A. Aegis A is intact, but over layed with the new. So both mage A & B would suffer the aegis while in the center(A from Aegis B and vice versa), if magi B remained outside aegis A he would get the benefit of his aegis (B) while mage A would continue to suffer.
The other view is that the new aegis needs to penetrate the original, so Mage A(original) would be fine as long as he stays inside his Aegis, if he tried to leave he would have to pass through Aegis B and suffer.
