So I had a fun idea...in the levels before you reach Basil in each tier there's a small chance you could get a level where you have to save/escort him. Perhaps in so much time, mini boss fight, or through a puzzle more complicated then most I've come across thus far...if you can call them puzzles. Anyways you have to save or escort him to the elevator and then when you reach Basil in that tier anyone who particpated can get a small discount or perhaps a few more choices in his recipes for sale.

Oh also to prevent abuse the level is locked no one can enter...so like player X can't boot players A,B,C from his party to invite his friends W, Y, and Z. ANd the other thing is that if you get the level to get the discount/bonus choices you have to finish that tier up to Basil without leaving to go back to Haven, or say to jump from your current party and go play with another.

Basicly it all prevents abuse and a huge economic shift (I think/hope). But could potentially make recipe hunting for players a little easier if they are looking for a particular recipe and don't wanna pay 2k plus extra to buy it from the AH. Also it could be a nice way to say you finally get the recipe you have been looking for but you only have 9000cr and you need 10k with the discount you could perhaps afford it.

NOTE I'M NOT SAY IT SHOULD BE A 10% DISCOUNT THIS IS STRICKLY AN EXAMPLE.
