Elemental Favor (Rank 3) Edit
By begging, threatening or cajoling an urban elemental, a Garou can convince the spirit to do her a favor by manipulating or even destroying her earthly shell. Thus, a glass sheet might explode at the Garou's foes; a door might refuse to open, even if unlocked, or a car's brakes might fail. An urban elemental teaches this Gift.
The Red Talon version affects the four classic elements - fire, earth, water and air - and a natural elemental teaches it.
The player rolls Charisma + Subterfuge (difficulty of the spirit's Gnosis). The Storyteller determines the precise effects.
