Dome of Arcan Warding blocks own mages teleports?

[stecal]

My own Dome of Arcan Warding caused of my mages teleport spells to the home castle to fail. Is this right? Will it block ALL spells 50%?

[Taqwus]

Yup.

Well, not all; if memory serves, domes don't stop spells originating from the same province. But otherwise, they don't discriminate. The same holds for automatic counterattacks by Domes of Flaming Death and so forth.
