Combat:
Lupins fight in packs, surrounding their quarry and darting in to attack and backing off to allow another member of the pack to attack.  Lupins are commonly found carrying silver weaponry since they are known werewolf hunters.  

Lycanthrope Detection: All lupin are allowed an opposed Wisdom check against a lycanthrope in their demi-human form.  When rolling to see if the lupin detects a werewolf, he gets a +9 bonus to the roll.  Other lycanthropes allow only a +2 bonus to the Will check.  If a werewolf is discovered, the lupin lets out a howl and then attacks without mercy.  Other lycanthropes are attacked depending on their type.  For instance, a werebear or a wereraven may be allowed to pass as long as they do so quickly, but a werefox or wererat would be instantly attacked.  

Allergic to Wolfsbane: Lupin can be turned as undead if wolfsbane is brandished before them.  The ingestion of the herb is deadly to Lupins.

Skills: Lupins receive a +4 bonus to Listen and Spot skill checks.
