Luckily for Rin, Stocke's already shaking off intangible edges, solidifying. He'll need to be in a tangible form to "bleed."

There's a few uncertainties here yet - Stocke still doesn't have a good reason to trust Rin, besides words, and there's no saying that Mana's magic will go the way she wants it to. But... though the shade pauses, it's not a long one before he nods sharply. He'd already decided it was worth those risks heading over here.

"How much do you need?" Stocke reaches for one of the glass vials even as he asks, flipping it upside down in his hand. He digs one claw into his opposite arm, making a short, shallow cut, and holds the container over it to catch the dark smoke that spills out.

Charcoal, mist, like something insubstantial. The wispy tendrils have nearly nothing of blood left in them, but that they're coming from an injury; they stop rising only when they hit the upside-down bottom of the vial, curling like true smoke.

Stocke inclines his head, acknowledging; he waits until the smoke in the vial's progressed from a muzzy gray to entirely opaque black, then stoppers it - still upside down - with a finger while he reaches for a cork.

Once it's sealed and flipped right side up, he holds it out to Rin.

He doesn't bother covering his still slowly "bleeding" arm, dropped back down to his side - though without a container holding it in, the smoke dissipates quickly. Maybe there's nothing to do with that but wait? Can't really slap a band-aid on it; that's not airtight.

Stocke's eyes flick sideways to his arm, then back to Rin. "It'll heal," he answers. He doesn't elaborate, but he doesn't seem concerned, either.

He's tried sealing in smoke with bandages before. It... it doesn't work well. In solid form, he can at least cauterize wounds shut - but it's almost a fifty-fifty chance the light and heat required will harm more than it helps. For something this small, it's not worth it.

"What else are you still missing? For Mana."

Hmm. The shade's eyes narrow. "A lich?"

He actually does know what Rin's talking about, though he hasn't met one personally - the ones on the network were pretty noticeable, weren't they? But if any of them mentioned that name, he didn't note it. It's the term "lich" he doesn't recognize.

He can guess Rin means one of the new kinds of monsters, though, and he's... sadly lacking in familiarity with any of those.

"Tell me what to look for, and I'll keep an eye out," the shade offers.

Right. Stocke tucks away the bit about the special item; rotting flesh he'd heard, that he hadn't. It's sure to come in handy. "I'll watch for one."

And... that's it, isn't it? Stocke steps away from the counter, though he does glance back at Rin to make sure the harpy isn't going to stop him for something else. If Rin doesn't, the shade heads to the door.

He doesn't say 'Let me know once you have Mana's spell working,' - he figures that's a given.
