[Question]Item selling with a token as currency

I know that this has been asked for many times before.. but I can't seem to find it..
My server has a problem with the Tier4-6 vendors.. they give the items for free.. but the tokens still drop from the bosses.. so.. I ask you.. how could I add the token request to the items?

i got the same would be nice if i did get any answers

are the tier 4-6 using the ascent gmisland.sql? if so they should have to be used by tokens
