Can you cast a spell and move in the same turn?

It's static.

Can a mage prematurely interrupt the effect of a spell if he suddenly wants to move from his position? Or does he have to either cast a fire shield on himself or stay put, muttering "This is fine"? If an opponent starts their turn inside a wall of fire, do they take damage when moving to other cells within the wall? Does the opponent take damage for moving through each such fire cell, or is the damage dealt only once, regardless of the number of cells passed through? If a character is pushed into a wall, do they take damage?

How permanent are the Necromancer's transformations? If the transformations are permanent, can a character change their age through transformations and, in essence, not know old age? Can transformation be used to cure chronic (and other) diseases or injuries? Can transformation be used to heal injuries and restore lost limbs? Can transformation be used to restore one lost limb at the cost of another?
