Well that wasn’t as hard as I expected. One Meta-Event run this morning and I completed my Leystone Light Armor – except for the helm.
As it turns out, after the Meta Event, Noxious Pods show up in all the camps, and the Way Points are active, so you can port between them and collect more than 20 pods for about 40 Crystalline Ore. This morning in one run, I got a Leystone Boot Box and enough Ore to buy Gloves. So with what I got yesterday, I now have a complete set except for the helm.
Here are some shots of where the Noxious Pods are around the camp, for an example. They are not that hard to find if you hold the CTRL key down while you pan around.
