It was true. After advancing from Iron, I am not 'stuck' at Jade for the last 7 years, I'm just waiting for an exceptionally large lightning incident to happen, or to meet a strong magical beast with lightning properties. Then, by killing the beast and absorbing its remnant energy into myself, I can fortify my foundation better. I can still advance without any of those, but that'd cause a bit of trouble in the future that I can just ignore by waiting patiently.
