Rank 2 Planetary Gift (Shantar)
The Garou can figure out what’s wrong with a device and make on-the-spot repairs which allow the item to run or function for a short time.
System: The player Intelligence + Repair (difficulty 7). One success allows the character to repair the targeted item so that it runs for one turn. Two successes enable the item to work for one scene while three successes or more indicate that the item has been permanently repaired, barring excessive use or subsequent damage. Failure means the character cannot repair the item, while a botch renders the device unable to be repaired by anyone — ever.
