Lineage 2 Adena

Lineage 2 Adena
Now, Lineage 2 Adena alchemists can transmute water to air, which is nice to have, as air can be somewhat difficult to farm sometimes. On my server, primal air is the most expensive primal of all, and the least available, likely owing to that it has no particularly awesome farming spot (use my search bar if you're interested, I think I covered good farming spots in another post). Also, the recipe to transmute primal water to primal air is indeed a revered reward from the Lineage 2 Adena Cenarion Expedition, so a huge amount of people aren't going to be doing it.
What it comes down to is patience. The cooldown on transmuting Primals is a long one, so it isn't as though you'll be making a ton of gold a day by doing it. But, you WILL make gold. Primals are one of the most easily sold items, in my opinion. I always sell mine through the trade channel, and they always sell well, if you undercut the AH by a gold or two. Again, the problem is simply time taken to transmute. If anyone wants to try this, my advice is to grab up multiple Primal Waters at the lowest price you can, and keep them in your bag to transmute whenever you can. When you market them in /trade, be sure to give the Lineage 2 Adena option of buying them individually, in case someone doesn't want "10x primal air!".
L2 Adena
L2 Adena Crystal Infused Leather, aside from sounding very cool, is used in most high level Leatherworking recipes. However, it's kind of a specialty item in terms of where it comes from. It sells anywhere from L2 Adena 10-15g per stack on my server, so it's worth it to grind for it. It's not very hard, either!
Head to Hellfire Peninsula, and grind on Quillfang Ravagers. Kill, skin, rinse, repeat! Hold onto the Fel Scales they may drop, and keep your fingers crossed for greens! This is a somewhat L2 Adena out of the way spot (check the map for location), so don't worry about too much competition!
This isn't fancy: skinning is a straightforward deal! File L2 Adena this info away into your list of good gold grinding spots, or for when you roll a Leatherworker.
