This was just a random idea that I tried to flesh out today, but it still needs some work. I really would like some feedback. Thanks!
The Wizard Duel
If an enemy wizard is in LoS of your wizard and within 12 inches, you may challenge them to a wizard’s duel.
If the enemy wizard accepts the challenge, both wizards roll Will. The wizard with the higher result has taunted his/her opponent more effectively and all figures (except the wizard) in the winning wizard’s warband receive a +1 to Fight and Speed until the end of the Wizard Duel.
If the enemy wizard declines the challenge, both wizards roll Will. If the wizard that was challenged rolls lower, all figures (including the wizard) in his/her warband are demoralized and suffer -1 to Fight and Speed for the rest of battle.
Rules of The Wizard Duel:
No group activation during the Wizard Phase.
The wizards must move towards no another until they are at least 6 inches from one another.
Weapons are not allowed unless the wizard has cast a spell to enchant them himself.
No other figures can attack these wizard, except for wandering creatures.
The winning wizard may choose to either learn one spell from the loser's spell-list or pilfer the loser's body for one item.
