According the topic
Armor sets (DKS), the Wild Dwellers Cuirass is also in one of the chests near where you first teleport to on Sentinel Island (across from the one containing the Blood Echelon Cuirass).
The Wild Dweller Leggings are in the Temple of Doom in the bandit camp (you can only go through it once), at the end of the lava section. Depending on your level and health, it may be difficult to reach. Jump so you land in front of (and below) the chest (no need to try to get onto the rock it is on). After that maybe pause to give you time to move the camera focus so you can open the chest, then do a back flip out, possibly landing in the water behind you and stopping the fire damage.

Help/Tips/Tricks forum), below the banner and text menu, above the list of topics, there is a 'New Topic' button (left of the 'Forum Options').
