With dragon claws coming soon, there should be a mechanism to convert our Head scales to Weapon crystals. Something simple, maybe using our unused mastery of Dragon ingenuity (at 10/level).
The current system takes a full scale slot (head scale), but when Claw slots are functional, it would be MUCH better to use a technique space on a scale slot rather than a full scale slot (as in socketing a talisman in a claw versus foregoing a teched head scale).
I'd rather not be at the whim of biped talisman makers, but could be done.
Anyway, the head scale formulas will generally be worthless when claw slots allow weapon crystals. So some content adjustment will be needed by the Kirascent researcher.
