I'm at the point in the companions questline where I'm going to meet the circle at the underforge. I remember from previous playthroughs that the werewolf is pretty weak and I'm wondering if there are any mods that buff the werewolf and make is more enjoyable to play as one. Hopefully these mods can be installed now and don't require a character that hasn't started the companions questline yet.

Also should mention I don't have any DLC.

Moonlight tales looks fairly nice. Not sure if it requires dlc though.

the best start to enhance your Werewolf eexperience would indeed be to get Dawnguard. this adds a Werewolf perk tree, and many of the newer (and better) werewolf overhaul mods extend based on that (i.e. they require dawnguard).

i can recommend Moonlight tales, too though, and it doesn't require any of the DLC (though more options become vailable, should the DLC be installed).

Moonlit Tales is practically required if you play Skyrim on PC in my eyes, even if you don't play as a werewolf because of how much it adds to the whole "were-creature" aspect of the game.
