New to the game: questions/comments

Yep, understood. No problem about that... just release ehhehe (kidding)

The quests are easy enough to do with sneaking and not obfuscate.

There are several clans and bloodlines that have Obfuscate as a clan discipline, it's not unique like Serpentis, Protean or Obtenebration.

It's a discipline which affects perception, something the Malkavians are also quite adept with.

Dementation, Quietus, Thaumaturgy, Necromancy, Thanatosis, Melpomene, Mortis...

Obfuscate is, in the basic clans, a discipline of Malkies, Nossies, City Gangrels and Assamites (some of them, the most physical)
It's an innate discipline, therefore it's quite commun

My list wasn't meant to be exhaustive

And a couple of those ones aren't restricted to one clan/bloodline either. Mortis doesn't exist in modern nights instead existing as Thanatosis and Necromancy.

I really need to prod my RP group to play a vampire game again, I never got to finish my last one.
