Without a doubt this is *the* fantasy animal. Only females can tame and ride Unicorns. Males can not tame or ride Unicorns, but can have them transferred. Mana and hit points appear to be similar to that of a Ki-Rin (300-330 hit points and about 200 mana) When wild, they will attack ANY creature with negative karma, including humans and tamed pets. When tamed, they will not attack humans or tamed creatures, but will attack anything else with negative karma.
Like the Kirin, the Unicorn has a special ability to help it's master when in trouble. If the rider becomes poisoned and their health drops below a certain point(40HP), the Unicorn will attempt to cast cure on them using it's magery skill. Once it succesfully cures the rider it cannot attempt to cure them for another hour.
In addition to this the Unicorn is also completely immune to poison.
Originally the Unicorns special ability was to open a gate to safety for it's rider, but due to some problems with that ability and the no gate/recall nature of Ilshenar, it was changed to the poison immunity and curing ability.
