[X] Total the Potency of enemies killed this way, allies of potency equal or less to that amount have their qi fully restored, all traits buffed by 1 for the duration of the scene, and the potency of their next technique is increased by 2
I think this is a very practical option in terms of mass battles. It allows us to drop a qi refresh and scene-long all-around buff on allies of note, plus gives a notable one-off boost to their efforts, which could mean battle-changers of their own. Notably, these buffs aren't limited to offense, or defense, or utility. It's all of their traits and any one of their techniques. Could be an attack, could be planting fortifications, a heal, leadership effect, control effect, etc. The two buffs, traits+ and tech++, should also be additive in their effects. I don't think that means an effective +3 potency for the tech, but traits are the bedrock from which efforts are realized, and that will have an impact on techniques unleashed.
But even on a thematic level, I prefer this option. It really leans into the potential unleashed by Winter's demise. Not just the reemergence of life, but the room and energy to create new things in new ways. I want to enable our allies in that way. I think it cuts closer to the core of Ling Qi's aspirations, in ways that even she doesn't fully realize yet. Can you imagine Zhengui getting supercharged by this? Not just on the elemental level of wood's resonance with Spring, but the thematic resonance of his cycle of Renewal with ours....
To me, that's an amazing prospect. We might get to see that green flame of his again sooner than we expected, this time in the material world.
