Because why should Heroes have all the fun?
Here are a few generic Talents that can be assigned to all sorts of monsters. They work much the same way as Hero Talents,
This is a work in progress, and your ideas and input are appreciated.
Clearsight - As per Hero Talent.
Cowardly X - Each time a friendly monster is slain, roll 1D6. On a roll of X or higher, all Cowardly monsters attempt to flee the battle.
Darkseeing - as per Hero Talent.
Demonic - Monster is immune to non-magical damage. Takes double damage from holy attacks.
Double Damage - Inflicts double damage with each successful attack.
Elemental - Monster is immune to non-magical damage. Takes double damage from its opposing element.
Fear X - Monster reduces opponent's Attack Strength by X.
Frenzy X - Each time the monster takes damage, roll 1D6. On a roll of X or higher, the monster gains +1 Attack Strength until the end of combat.
Instant Kill - If the monster rolls a double for its Attack Strength, it kills its opponent instantly.
Leader - Each other monster of the same type in the area receives a +1 bonus to its Attack Strength. This effect is not cumulative.

Monsters could also have Special Skills assigned to them, for those creatures that are particularly good at a certain ability (e.g. Climb, Dodge, Jump, Strength, Swim). A monster only Special Skill could be Flight, where the higher its score, the more agile it is in flight.
