I have 13 Prismatic Philters I don't want or need. I would be willing to trade them for basically anything, but I prefer chocolate coins.
Edit: 10 remaining.
Edit 2: 7 remaining.
Edit 3: back to 10.
Edit 4: 8 remaining.
Edit 5: 1 remaining.

What kind of catalysts would you be looking for?

Any. I only have [Ny'vene] Mountain King, [Kelpari] Cruel Specter, [Zolnixi (Aged)] Frozen Dew, [Sylvorpa] Black Widow, [Luffox] Enchanted Lake, and [Faelora (Aged)] Ghostly Revenant.

In terms of spare reg catas, I have one Haunting Spirit Aurleon, five Pomegranate Bulbori, four Chilly Dawn Draeyl, one Ghostly Faelora, three Plum Faelora, two Enchanted Lake Luffox, one Toxic Cloud Lunemara, seven Pumpkin Lunemara, seven Vampiric Morkko, one Voodoo Nytekrie, one Potion Sylvorpa, and three Ghost Vulnyx. Whichever/however many of those you want for as many prismas as you think is appropriate; I'm doing a max stat project and need a lot of prismas.

Well, I am looking for a variety of materials, so for catalysts only I will give you three prismatic philters. You can decide how many you think that is worth. If you want more than three, I would rather you pay in chocolate coins.

I sent over some catas for the three philters. What price were you thinking in choc coins for the others?

I would like 300 chocolate coins for each, but I'd go for 200-250 each if that seems excessive. So basically, anywhere from 200-300 for each philter. It's up to you what the final price is.

Three more at 250 choc coins each, then, if you please :)
