New NIR and optical spectra of the outbursting comet 12P/Pons-Brooks detect crystalline water ice at 140-170 K and gas ratios indicating typical C3 but depleted C2, with outburst kinetic energy of ~8e3 J/kg supporting amorphous ice crystallization as the trigger and a refractory-to-ice mass ratio of
