Since this post got bumped. I'd like to remind anyone looking to try any of these potions that they can pm me in-game at Kerrlahg if you'd like to give one of them a try. Not many people use these and it's partly because they often aren't available unless you want to buy r1s at a shop someone across the map, and uptier them. Fortunately, I've already taken the liberty of making r7 masters of all of them and can craft 'em, and we could even work out a deal if you need higher ranks (I'm well stocked on materials at all times).
I want more people to try them, it's like an equipment spot that most people leave empty. People spend millions uptiering legendaries but won't spend 25k for 1 hour potion time with a powerful proc. There are some powerful ones that are very seldom used, like the succubus one (vamping is popular still right?)
I highly recommend farming with a potion, if you kill quicker, you reach your goal quicker. And isn't that what we are all trying to do?

Cheers all.
