I am not certain that the vials off the viper pit quartermaster work as stated but a lvl 100 vial can be used with 3 cheap waters and the lvl 90 stuff off the viper pit qautermaster to make gimpy potions. Still, that should allow some to skill from 100 to 135. And I bet it would work with lvl 100 mats (especially the energy concoction mats, they require less stabilizers than healing potions), which means 145 is attainable.

The cost per vial is 5s which is cheap compared to Purified water off the AH (like 20s each or more).

Eventually we should get access to lvl 150 vials which will make getting to 180+ pretty easy.

* The WHITE leeches (not green) which are on the AH are the easiest health pot ingredient to skill up on since they require the least stabilizers to make a solid insta heal potion. For example: the level 60 Clutching horse leeches only need 3 distilled waters (apoth vendor) and make something like a 500 and then 800 hp insta pot (depending on your apoth level). They can be used to skill to 100-105. With a little work you get to 110 and use the next level of leeches, Withered Leeches 110 (Think they take 1 purified and 2 distilled, so these should work with the guild vial 100).

* I am 99% sure the 1.5 s level 50 vial on the viper pit quartermaster is the same as the 30c vial off the regular apothecary vendor.

* The apothecary vials on the viper pit vendor have gone through a number of wierd changes from Mythic, so dont be suprised if they get modified again (originally they were supposed to be 90 and 140, now maybe they will have 50/100/150, but really, who knows)

I have not browsed around IC much. Where is the Guild Merchant?

Thanks for the rest of the info. I had used someones tip (yours?) to raise up my apoth to the 100'ish point farming humans for the leeches and water. Also a good tip for anyone else who is just looking to make cash - leeches and waters fetch a good price at auction house.
