Half-Lunar Shape-changers

Lunars God-Blooded, be they Beastmen or Half-Castes, will allowed access to Knacks (as their Essence allows).  This however should be a uncommon event, but I am going to allow it.

They however, can only purchase Knacks during Character Creation, and the cost the same as parental Charm.  This would mean only the truly powerful Half-Lunars (those with high Inheritance) will have any real chance of getting powerful knacks.

They can also only pick up knacks their lunar sire possesses.  Thus a Lunar who cannot take the shape of a Horse cannot spawn a Child who can turn into a Horse.  This limitation applies to their Spirit shapes as well.  They can only pick Spirit Shapes of their Lunar Sires.

They also have the same Lunar Tell as their Lunar Sire – perhaps with very minor variation.  Should there be two Lunar sires, they possess the tell of the Lunar from whom they inherited their Spirit Shape.

Once past the character creation stage the Half-Lunar can no longer acquire new knacks or even new Hart-Blood.  Their shape changing capability are forever locked at birth and is not something that can be improved upon.

As a further clarification

The “human” form of a Half-Lunar with knacks is their normal form.  So Half-Lunar Castes are simply their human form, and Beastmen’s are their Beastmen form.  Thus the “human” form of Simian Beastmen of Raksi’s is their Beastmen form.
