Maybe, I just want to iron out those rules. We have had A LOT of discussions regarding matrix rules, and I am pretty confident in them by now. Magic is foreign to me yet. Until proven otherwise, I'd like to set the rule and keep to it in future encounters.
I've asked a quick question on the rule subforum, and the quick answer so far is in favor of blocking dual creatures by the mana barrier.
To me the matter isn't yet clear, but we can proceed with temporary verdict.
Netz, I assume that you think that mana barrier should block physical movement of dual being creature, as well as for example an astrally perceiving mage. I also assume that you Larz think the same.
