Air Dome

[Zeldor]

ano:

Astral window/projection cannot be stopped by domes afaik. So it cannot break them.

About that stacking:
Stacked domes worked earlier, the fix made them not stack. That is if you pass one dome, it shatters and it doesn't check all air domes for same spell. Stacking is good against multiple spells still, but you can no longer get 99,99% protection.
