In vanilla Skyrim, equipping the ring will instantly start the transformation, while with the Dawnguard DLC wearing the ring of Hircine will give you a power to transform unlimited amounts of time. The ring of Hircine is a ring you can get in the quest " Ill Met by Moonlight" by siding with Sinding and will allow you unlimited transformations for Werewolf Form. This however can be a problem if fighting enemies whose corpses cannot be fed on. In order to stall the inevitable transformation back into a human for roughly two minutes, the player can feed on the corpses of its victims in order to remain in Beast Form. Roaring or howling can also be used to scare certain enemies away in order to make defeating a larger group easier. Attacking while sprinting is one of the most powerful attacks in the game, as your werewolf slashes their claws at high speeds. Power attacks as a Werewolf are used to stun enemies and send them flying. Your claws are your only weapon yet they are extremely useful (although in some kill animations, your mouth can be seen eating the enemy). As a Werewolf, sprinting is much faster, stamina is greatly increased, and attacks do much more damage. Once you become a werewolf, you can never gain rested bonuses from sleep unless you find a cure. The Beast Form power can be used once a day unless you have the Ring of Hircine, and is used just like a shout.
