Diarmi, a bit too focused with the sword flying at his face, had managed to miss the moment of the lightning bolt - not its existence, fully, [i]something else[/i] had distacted katana-guy after all, but he hadn't seen what it was. A blade being pulled with the intention of cutting off one's face had a way of focusing one's attention like that. He practically held his breath as the spores began to take effect, making the young man stumble and swap. When he finally collapsed, Diarmi was quick to catch him before he cracked his head on the rooftop, then finished setting him down.

Well. Best to disarm him. As he grabbed at the katana's sheath, he asked aloud, "So what was that?"

"The spores of a mushroom from my time. They have magical effects."

"They do?" The sheath came loose with another tug. Diarmi thought about it, and then fiddled with the necklaces around the young man's throat. Hey, something let him summon and control those bird-monsters. He didn't know what, but magic charm or magic sword seemed like the best bet, and he wasn't sure what was enchanted. 

"Yes. For some, the mushrooms force them to sleep. For others, they bring them into the berserker's rage."

"They [i]what[/i]?" Diarmi's voice cracked. "I coulda had that guy go into a fit of rage at me? He was kinda already in one!" Rage squared, he supposed. But that was beside the point.

"Hardly. But, I will tell you, a berserker is immune to the power of metal and fire. Unless he used his sword like a club, he would not have been able to harm you."

Oh, this was not a train of thought Diarmi had ever anticipated. But here he was, wondering at what point being bludgeoned would be worse than being sliced or pierced. Maybe it was best to let that train go on its own, and he'd re-board it later, figure out the answer. For now, a drizzle had started and he'd heard the sound of broken pottery. The katana and possible charms secured on his person, he jumped, caught a lamp post, and slid downwards. Thank god(s?) he wasn't climbing up in the rain.

"Hey, hey, that was awesome!" He ran towards the knight girl, holding his hand up for a high five. "We gotta check on bear-hand lady, I know, but-?" He gestured with his free hand. "High five?"
