No, only the element spells can be combined anyway and even then only by certain heroes. My arch wizard and arch mage can't use element spells. The arch mage is a level five elf magician who gets three random elf spells as well and uses Alisa's movement but only defends with one dice.
The two arch magicians definitely make the best use of my progression rules:
Veteran: 2 white shields = keep the spell and can cast the same spell again this turn, 1 skull + 1 white shield = keep the spell, 2 skulls = can discard any of your spells in place of the one cast, 1 black shield + 1 white shield = cast as normal, 1 skull + 1 black shield = the spell fails but is kept, 2 black shields = the spell fails and is discarded.
Master: 2 white shields = keep the spell and can cast again this turn, 1 skull + 1 white shield = keep the spell and can cast the same spell again this turn, 2 skulls = keep the spell, 1 black shield + 1 white shield = can discard any of your spells in place of the one cast, 1 skull + 1 black shield = cast as normal, 2 black shields = the spell fails but is kept.
Legend: 2 white shields = cast without using an action and keep the spell, 1 skull + 1 white shield = keep the spell and can cast again this turn, 2 skulls = keep the spell and can cast the same spell again this turn, 1 black shield + 1 white shield = keep the spell, 1 skull + 1 black shield = can discard any of your spells in place of the one cast, 2 black shields = cast as normal.
