* The ability to howl, eventually gaining a morale boost buff from it that will increase your damage and regeneration. (Supposedly improves with the Howling subskill, altho the means to level up this subskill consistently and its effects are rather obscure).

* The ability to feed on enemy corpses (currently, no limit to what you can eat, even tornadoes!), gaining a very nice regeneration buff from this, for a duration that will depend on your Beast Metabolism subskill (the more you feed on enemies, the higher this subskill will go).

* Keep in mind that, once you become a werewolf, you'll be especially vulnerable to silver and wolfsbane, both in your humanoid and beast forms. Eating foods that contain wolfsbane, and being hurt by or simply holding a silver weapon on your hand, are sure to cause some serious damage and potentially kill you.
