The thing that staggers out of the forest, arms wide and head sweeping back and forth in a desperate search, is about the size and shape of a human child, but with purple-black, blistered and cracked skin over every inch of its body. Green eyes betray what it is, beneath the mask that looks like a constantly-moving swarm of beetles, but such a small, lost thing can hardly be a threat, right?

Its eyes meet Kuai's before he can try to freeze it in place and for a moment he's elsewhere, surrounded by the sounds and smells of something nostalgic, making him both happy and sad at the same time. Home, in a brief moment of peace. Hanzo.

But it's fleeting, thanks to the potion and Kuai lays down a jet of icy shards that race along the ground to trap the spirit in place before it can get any closer - because it sure looks like it's about to sprint right for him. Trap it he does, but in response the spirit's insect swarm floods (mostly) off its face, leaving only a few dancing over its features as the rest race toward Kuai on the ground and through the air. Walls and darts and icy terrain stops them all - or so he thought.

One slips past unseen. It lands on his back and seeks bare skin, and delivers a bite which blossoms with pain. Kuai finds the thing and smashes it instantly, but the venom is swift. Blisters sprout and burst across the surface of his skin as he's seared with an acidic burn that ultimately covers nearly a quarter of his body.

He'll recover in a week's time, thanks to the healing salves and potions, but until then movement is likely to be extremely painful as the tender, blistered skin bleeds at the drop of a hat until it's fully healed.

Meanwhile, the spirit seems solidly frozen in place despite its struggles to break free - so Kuai is free to get his revenge, or have a friend help out given the intense pain he's currently in.
