Tree Feller Scorpion

Large construct, unaligned
Constructed by Wegler from parts found in an ancient D’Aroine spire, the Tree Feller scorpion is a formidable opponent, especially for foes relying on energy damage. Within its body are eight complicated metal cylinders, each engraved with arcane runes. These cylinders provide it with its immunities.
While it is clearly a working machine, it moves with a certain grace and odd delicacy—something common to most D’Aroine constructs. Unlike a living scorpion, the tree feller lacks a stinger. In its place, it has a buzz saw designed to cut down a tree quickly and precisely. It also works quite well against flesh and bone, causing horrific wounds. While the scorpion was not built for combat, it is intelligent enough to fight with basic tactics—although this mostly involves the same approach it takes to trees: grab and saw.
It can be revived with Welger's Wrench. 
If a PC is attuned to Welger's Amulet of Command when the scorpion is revived, it will not attack and can be commanded by the PC. If it is revived and no one is attuned to the amulet, the scorpion will remain dormant.
