Amarine is a wild horse from the plains of Low'verok. She was tamed by Fianna's mother and given to the young druid on her 14th birthday. Amarine is a deep, rich brown with a black mane and tail, and a feral black stripe down her back. She wears a simple halter and only a blanket on her back instead of a saddle. Amarine isn't trained for combat, but knows the following tricks: Come, Heel, Seek, Seek, Stay, and Work.

Trip (Ex): A wolf that hits with a bite attack can attempt to trip the opponent (+1 check modifier) as a free action without making a touch attack or provoking an attack of opportunity. If the attempt fails, the opponent cannot react to trip the wolf.
Skills: *Wolves have a +4 racial bonus on Survival checks when tracking by scent.
Link (Ex): A druid can handle her animal companion as a free action, or push it as a move action, even if she doesn’t have any ranks in the Handle Animal skill. The druid gains a +4 circumstance bonus on all wild empathy checks and Handle Animal checks made regarding an animal companion.
Share Spells (Ex): At the druid’s option, she may have any spell (but not any spell-like ability) she casts upon herself also affect her animal companion. The animal companion must be within 5 feet of her at the time of casting to receive the benefit. If the spell or effect has a duration other than instantaneous, it stops affecting the animal companion if the companion moves farther than 5 feet away and will not affect the animal again, even if it returns to the druid before the duration expires.
Additionally, the druid may cast a spell with a target of “You” on her animal companion (as a touch range spell) instead of on herself. A druid and her animal companion can share spells even if the spells normally do not affect creatures of the companion’s type (animal).
Tricks: Dorenna knows seven tricks.
Lady Shatterstone, you can pick these tricks from the Handle Animal section of the skills chapter. In addition, there are some more tricks in Masters of the Wild (ask Brother Shatterstone). Also, if you want to make up some tricks, you may, though I would get final approval. I made up some tricks for people's mounts. For example, Honeybee, Jabin's mount, knows the new trick Rescue, in which she takes her rider away from combat. Saku's mount Viper knows a new trick called Savage, in which he attempts to maim an enemy.
