Like, apparently I shouldn't have let Adam have Tenebrous Veil, since it's actually "only known by anarchs, who will only teach it to other anarchs."
Wolf's Lament is in either Libellus Sanguinis vol 4, where it costs 7 exp, or Players Guide to the Low Clans, where it says it costs 14.
Wolf’s Lament (Dark Ages)
Animalism 1, Obfuscate 2
Description: In ancient times, the wolf’s howl echoed across the forests and mountains, communicating with its far-flung brethren. The Nosferatu and Gangrel living among the wilds of northern Europe learned how to do the same, resulting in Wolf’s Lament. This gift enables the vampire to howl a message out into the open, where it carries for miles. Additionally, any wolf hearing the wail supports it using its own voice. If done properly, a chain of wolves can sustain the lament across dozens and even hundreds of miles.
Anyone listening merely hears an eerie keening that pierces the air and settles across the land. Those with Feral Speech, however, hear a voice carried within the howl. The content is brief, but it imparts emotional imperative and a general missive. It can warn of danger, summon a specific individual, grieve for someone’s death or carry any other quick and simple messages. Wolf’s Lament can vocalize roughly two simple sentences.
System Description: To use this Discipline, the player relates the simple message and the Storyteller judges wheter or not it is too complex (saying it in one breath is a good rull of thumb). The player then rolls Manipulation + Animal Ken (difficulty 6) and the vampire sends out his instructions in a howl; the successes indicate the distance the message travels on the voices of wolves (see below). A failure simply means there are no packs in the area (or they fail to pick up the message), while a botch indicates that the caller attracts unwanted attention.
Successes / Distance
1 success: five miles
2 successes: 10 miles
3 successes: 50 miles
4 successes: 100 miles
5 successes: 250 miles
