I don't think that the hammer smashes the crystal. I think its' 'striker pin' might be made of some catalyst material that discharges the crystal.

However, Weiss also demonstrated that she can draw energy off of the crystals and that is how she created her platform runes and also cast the fast-run spell on herself. That does suggest something magic-like that is an inherit ability on her part, unless her boots have kinetic energy crystals that she was charging and activating from the energy stored in Myrtenaster.

Similarly, Adam and Blake's fast run spell and Yang's blazing fists and hair also are evidence towards inherit magic of some kind in some of the characters.
