Rank 2 Black Spiral Dancer Gift
This Gift grants the ability to burrow through the earth, creating a tunnel roughly the size of the digger’s body, which others can follow through. The werewolf must be in a form possessing claws to use this Gift. Mole-spirits teach this Gift.
System: The player rolls Strength + Athletics against a difficulty depending on the substance to be excavated (4 for loose mud, 9 for solid rock). Some alloyed metals (such as titanium steel) and other reinforced structures will not yield to the werewolf no matter how hard she digs. The character can burrow one yard per turn for each success. After the initial roll, the character doe snot need to roll again to continue at the same speed.

This Gift seems to be mislabeled. The only listing for the gift in the W20 book is for Metis and even in the W20 Book of the Wyrm there is no listing for it at all as being a BSD Gift.
You are correct! No idea how it got tagged as BSD, but it has been updated.
