Three questions regarding sacreds.

[Mind Elemental]

Yikes, that sounds pretty bad for the stealth units...

Are there any stealthy astral mages, as someone suggested upthread? Even then, your raiding squad would be vulnerable to e.g. fire spells, and it might just be worth pulling the trigger if the raiders were high-value units such as Vanir.

Back on the original topic, has anyone ever tried powerblessing with Tir na Nog? They resemble Vanheim enough that this might be viable.
