Henrix said:Marginally different.
A spell taking a full rouind action does not come inte effect until the start of the mage's next round.
Henrix said:That's interesting.
I am afraid that the only thng I can find regarding this is in PHB, p.148, "A spell that takes 1 full round to cast is a full round action. It comes into effect just before the beginning of your turn...", which implies that there is no such distinction.
And no, nothing in the FAQ or errata, either, as far as I can see.
