Dome Question

[Thufir]

In the case where one has multiple domes up, are spells applied on domes sequentially, until one dome is successful in repelling the spell?

If so, is the sequence a stack or a queue? I'd guess stack, both based on what seems intuitively appropriate and Zen's choice in ordering.

Again assuming that domes are ordered as a stack, it makes sense that Zen's ordering has Dome of Flaming Death cast Last, but it the surprises me that Dome of Arcane Warding is cast first. Since DoSA and FD both have a chance of being broken by incoming spells, wouldn't you want to cast DoAW after DoSA and FD? Also, sooner or later you'll have to recast DoAW anyhow, whereupon it would become top of the stack (at which point you might want to recast DoFD, I'd guess).
