Domes try to block every spell that targets that province. Even friendly spells. So it works on artillery spells, teleports, cloud trapezes, site search spells etc. Items that have buil-in spells like Gate Stone, Soulstone of Wolves etc also are blocked.
I really don't like some stupid AI decisions. My army would easily kill that mage with couple low-level free spells.
But yeah, 1 VP
12 months till next one, who wants it?
P.S. I am not sure if I really get that part about blood slaves. I like my blood slaves. And who else has them anyway? I know about you and Pythium [gift of kurgi
].
