Cu-Sidhe

Cu-Sidhe are an elven breed of canine. Their fur is patterned like tree bark, giving them excellent camouflage; so long as one remains still, there is only a 10% chance it will be detected in forest terrain. Even indoors, underground, or in non-preferred terrain they are able to hide such that there is only a 30% chance of detection. They have Darkvision with a 60 foot range, and particularly acute canine senses. As with most canines, they prefer to attack as a pack, and will generally avoid combat if met singly.

Most cu-sidhe are much like other wolf or dog breeds, loyal and obedient pets and working dogs. One in six pups born is a special exception, having human-level intellect and the ability to learn magical skills. These special cu-sidhe can detect magic and detect invisibility at will. A magic-wielding cu-sidhe can cast a form of growth of animals on itself twice per day, lasting up to 1 hour. This also grants a temporary 2d8 bonus hit points while enlarged (as if granted by a potion of heroism). While enlarged, they may be used as mounts by small or medium characters.

Special cu-sidhe are only hit by weapons which are silver or magical; furthermore, so long as one has at least 1 remaining hit point, it is able to regenerate 1 hit point each round. However, if reduced below 1 hp, a cu-sidhe will die like any other creature. They save vs. all magic with a +4 bonus.
