hi there

i got a question guys i hope someone can help me with. as the titles says. i would like to know how to reset knowledges' ranks that are non-ecology types? cause i recently got the tranan underfoe treasure chest (or something like this) knowledge from the blacksmith in velia and got it with rank "c". and i want to have it at max rank so with "s". i know how to reset ecology/monster knowledges but do not know how to reset these type of knowledges. does anyone know? :)

thanks in advance my friends and sorry for my bad english

Would that be the Tranan Lead Shot Chest in the Trade->Munitions of Balenos category?

I dont think it can be deleted. Maybe it was possible with elixir of oblivion but that item has been removed from the game.

The rank on all the trade item knowledges are at least very irrelevant to the game atm cuz trading with trade goods is very dead and in dire need of an update.

Is it not possible to raise the knowledge of trade goods by right-clicking them again?

No, it says you already have the knowledge.
