sure m8
when in a battle press alt
then u see healthbars and there is a number on them
that number indicates who is first
1-9
when in a turn
for example
your horseman
have 1 this indicates they are first
now when u press the wait button(it will be at last, the horseman can move and u can press wait). so this unit will now be the last one to act
now when he is able to to be again u can use him again to attack or something
wait is very important in this game
furthermore casting scrolls doesn't cost mana
instead
as a warrior u may only cast once a turn
now when u have casted at the beginning of the turn you won't be able to cast this turn again
you have to wait until the last unit has done it's move for example last unit was 9
then the new turn begins with the unit that has highest initiative
now u can cast again
or wait for a better time to cast again this turn
for a a mage he has the ability to cast twice a turn
but that is another story
