The wine will do nicely. Given who he's trying to talk to, Felix almost wonders if too fine a wine would count against him. The best fruits of summer. Winter is only a time of plenty in the beginning; this seems more the season of working slow as possible through one's stores. But they're not down to the dregs for a while yet.

Troll souls suit him fine too; he might feel a little guilty if they came from creatures he liked. Felix nods and considers Danny: he knows magic involving souls is less... common, perhaps, in other worlds. He's been wondering how his young friend will react as he understands more of what Felix is actually doing. He doesn't seem unnerved at all now, which is good.

Provided he doesn't prove too comfortable with it. But that's a problem for Future Felix.

"Of course." He grins, dark hair falling into his face as he looks up from the gems. Felix brushes it back and points out bottles as he straightens. The potions seem to be color-coded to their purpose as he points them out; perhaps the bottle shape is significant too? It's hard to tell. "Healing, warding the cold away, reinvigoration when you're exhausted- physically, that is. This one restores your mental and magical faculties: excellent if you're doing a lot of spell-slinging, or if you accidentally push yourself too far."

He nods at them all. "Once you show me the shop, you can take your pick." A formality, really: he thinks Danny really does want to see him work, and that precludes cheating him on the workspace. Still. "I'll need some time to prepare the ritual, but as I promised, you're welcome to assist me."
