This is a thorny issue and honestly, I haven't really sat down and explored the semantic mechanics of it.<br/><br/>Off the top of my head, I was under the impression that you couldn't brew CL4 potions because Brew Potions was for CL3 potions and below?<br/><br/>Regardless, I'll be happy to review the matter, but I sort of feel like you're sort of confusing me more than clarifying things for me.
