Which combinations of these catalysts would get me the most greater/lesser vials?

Uh, how many greater/lesser vials do you want? I don't really need too many so just let me know :)

Oh dear, technically I want as many as I can get my hands on (all of them) but.... 67 lesser and 1 greater...?

Which of the catalysts and how many of each would you want for that?

I already have too many catas so, probably don't need any of them. Also I gave 20 of the lesser to my sister because she needed some.
SO I just gave you 20 of the lesser blood vials? I might need the other ones but probably not xD I will keep it just in case (for now)

Ahh, ok. Do you want anything else for the 20 lessers?

What do you have?

I have a few extra avatar items, which ones are you missing/looking for?

I have no idea; if you tell me which ones you have I can check?

Would you take 10-30 diamonds for a greater vial?

how much do you want for the following catalysts

all 3 Vampiric Morkko catalysts

both Cosmic Witch Qitari catalysts
