I used your excellent guide for most of my trades kills over the last several years, thanks Kitty.
It's worth mentioning that it's no longer necessary to subject yourself to the mind-numbing grind for deep water inks for Alchemy and you can now achieve skill 350!
In February 2015,
Philter of Concealment was changed to 350 trivial. It costs more per combine (approx 9-10pp but the result sells for 3pp so ~7pp net cost) but the lootable ingredient is exceptional shissar blood, which is extremely abundant in shadow haven (50% off trash, 75% off bosses), which is far more common than deep water inks. In a single clearance of sirens you can maybe get 20 inks. In the same time you can easily get 60+ bloods (and the zone is so much easier to navigate). As an added bonus, xp is way better and you get some drops if you do the bosses. Plus loads of radiant crystals of course.
I'm now Alchemy 316 and rising, from around 290, after only 3-4 very short farming sessions in SH. So much better than deep water inks and gets you using the custom content at the same time (thanks BTW Lillu).
PS this also means we don't have to bug you to do our 3.0 combines this time
