I can suggest the following neutral units: Wandering Mage (casts one random destruction spell on the enemy per turn), Condottiero (possesses the deadly strike skill – can eliminate half of a unit with one attack with a 3% chance), Seeker (heals all troops for 50 health), Heretic (immune to fire, attacks with a fire whip).:confused:
The Condottiero you suggested is basically an absolute Death Knight from the existing neutral units in Heroes 5.
