Water 9 Blessing

[Mardagg]

Hi all.
What exactly does quickness do?
I just started playing dominions again after a several years break and i seem to renember from Dominions 2 those quickened Priests,that were able to cast smite 2 times per turn.But in my current SP game,my atlantian level 3 priest only cast it once per turn,every turn?!?
Did it change somehow?
What about sacred melee units?

Thanks in advance.

Btw, i love most of the changes from dom 2 to dom 3.
A great game became even greater!
