I don't know what do you mean about "mix of attacks".In tbe first phase of an attack you can't use regular attack. You only can use ranged / siege attacks (or niether one), it depends upon how fortified your enimies are.
Regarding the 1st phase of attack:
-If enemy isn't fortified, you can combine ranged + siege attacks.
-If enemy is fortified (because the symbol on his token or because the site his belong) you can only use siege attacks.
-If his is DOUBLE fortified (because he has the symbol and his is on a fortified site) you can't hurt him.
For example, cities , mage towers and stronghold are fortified places.
I hope that helps. :)
